Here is our current calendar of upcoming events.  More information available by clicking on the event below.  We invite everyone interested in film photography to join us, though we specialize in LF and ULF, we love all film.  Hope to see you at one of our gatherings!



For one day the studio space at DCP will be stuffed full of photo gear for you to buy or trade. Expect to find the usual and the very unusual on 24 tables of cameras, lenses, lighting, bags, doodads. . . we’re not sure what will show up! If you’ve never been to a photo swap meet then you’ve been missing out!

DCP is hosting this event with help from Don’s Camera, the best used camera store in the region.

Whether you’re a professional dealer, full time photographer or just a hobbyist with a spending habit and a closet full of stuff to get rid of then rent a table and come be a vendor. If you just want to sell or trade a few items you can buy a ticket and see what kind of deal you can make with one of the vendors.

Doors open at 10am and close at 4pm. Entry is $5 cash at the door. Kids 12 and under get in free.



We have arranged for DFW area photographers to have a meet up and print share at a space in the Deep Ellum area of Dallas.

We will meet Saturday August 1st (2015) at 11:00 AM at;


2614 Elm St. Suite #120

Dallas, TX. 75226

… then go to lunch afterwards somewhere in the area.

As we’ve done before, lets’ start with bringing as many prints as you like (or none), but let’s limit our presentations to 4-6 photographs and 5-10 minutes time, depending on how many we have. We want to make this a monthly thing, and now that we have a space (always the problem before) we are in a better position.

Thanks to Augusto Schillaci for arranging the space!!!

Hope a large group can make it. Come whether you have anything to show or not. See you there!



We have just updated the FORMULAS area here on the BLOG (click the link at top of the page).  What you will see is mostly cosmetic with a few corrections here and there.  The formatting of the older area was made of screen grabs of notes and was not that well organized.  Hopefully it is now a little more tidy.

Very little changes in the realm of the wet darkroom and film photography.  There are no fads. . . no here today, gone tomorrow. . . no high-tech gadgets. . . no amazing updates.  Traditional film photography is a craft you learn; fine tune; then use.  The bottom line is the finished fine print.  Traditional film photography is very old fashion and grounded in down-to-earth proven techniques, that once learned are the backbone of the art form.  Bottom line; not a lot to stand in line or camp on the street to be the first for some new-fangled gadget or upgrade.  Once you master the technique, there are no excuses not to produce finished work.  Film photography is a craft; you learn it; then you use it; for the rest of your life; and you pass on what you have learned.

In our Formulas area you will find the mixtures we use.  Nothing very special about anything we do, and it would be a good assumption you will see little new there.  Take what you can make work for you; leave anything else for the next interested photographer.



Numbers can not quantify a feeling. . .

A fine photograph has A LOOK; A FEEL; A PRESENCE; there are qualities that cannot be measured or codified.  They are seen and felt, yet have no tangible attributes. . . some things are impossible to put into words.  You can run tests, plot curves, generate computer models, but the emotional response, if any, to a photograph is an experience and not a quantifiable known.

In the process of making the fine photograph there are subtle adjustments that the photographer literally pours into the image.  These fine adjustments may actually not even be perceivable to the viewer, but they make or break the finished image.

In the creative process of making a finished print, there are no hard and fast rules.  There are photographs that take on a completely different atmosphere than may have been seen or felt at the time the film was exposed.  These are those “happy little accidents” as the painter Bob Ross would say.  You may follow one direction you believe will make the image speak when in the field, which is totally abandoned in the darkroom at the time of printing.  You make your best estimate as to what you believe you will eventually end up with, but you will not absolutely KNOW for sure what a film, paper, developer combination is really doing until you make a real photograph.  It is all about that feeling.  Do not allow yourself to get locked into any preconception.  Allow your creativity to guide you.  Do not get hung up on numbers or any hard and fast rules.

I keep coming back to the same point; you can not calculate feeling.  There are some things that just exist and are not possible to be explained by a mathematical expression. . . they are emotional expressions. . . emotional responses. . . subject to any number of personal preferences of the individual. . . these preferences are the product of what make each person an individual. . .  you cannot measure these things. . . they are subjective.    Think about it. . . can art really be created and expressed by numbers???

It is about personal taste. . . Ford or Chevy. . . Coke or Pepsi. . . red or blue. . . one size does not fit all.  What you may find perfectly acceptable in a film developer combination may not suit my taste at all.  My father used to say, “that is why they paint cars different colors.”

Keep in mind that any hard rules or numbers are only a starting point. . . only a suggestion.  Creativity comes from reaching far beyond hard figures and rules.  The creative spark reveals the inner feeling by stirring the imagination with creativity.



Had an interesting discussion the other day with a group of photographers about the Thomas Duplex Super-Safelight.  This is one of the best safelights you can own.  They are bright, powerful and will fog your paper before you can say Look Out!  Honestly, these things are designed to light a very large darkroom, I would say, far beyond the size that most of us are accustomed to having the privilege of owning.  They come with several glass-mounted filters that are designed for different darkroom uses, but there seems to be a lot of confusion as to what filters to use and how this all works.

So, let’s begin by trying to better understand just how the Thomas Duplex Super-Safelight works.  This is really an ingenious device that uses technology designed for something completely different.  If you have ever looked inside of the unit you will see a strange looking glass lamp.  This is the heart of the Super-Safelight. . . a Low Pressure Sodium lamp. . . designated in the industry as an SOX lamp.  Without getting into a lot of very technical talk, this SOX lamp is an extremely bright light producing device. . . you get a lot of light per watt of electricity used.  But there is a trade-off. . . the spectral output of the lamp is extremely narrow.  In the simplest terms, there is a lot of light, but it is just one color.  How this narrowband light is generated and the details of the lamp itself are way too complicated for this discussion.  For the photographer, how to use the lamp is much more important.  You do not need to know how to build a car from a block of metal to drive it.  If you are really. . . really. . . really. . . interested in the technical stuff, here is a LINK.  Also an Internet search will turn up even more technical info.


Electromagnetic Spectrum


Low Pressure Sodium Lamp

What we photographers are really interested in is the spectral output of the lamp.  The SOX lamp produces a virtually monochromatic light, averaging about 589.3nm wavelength.  I know, more of that technical talk.  What is important to know is that this wavelength of light from the SOX lamp is outside the main spectral sensitivity of B&W printing papers.  This is what makes the Super-Safelight unique.

So, roughly speaking, we can say that graded papers are mostly blue sensitive, and VC papers are mostly sensitive to blue and green light.  Again, roughly speaking, graded papers are mostly sensitive to about 450-500nm wavelengths.  While VC papers are roughly most sensitive to about 400-570nm wavelengths.

Now with a rudimentary understanding of the SOX lamp spectral output, it becomes obvious that it is well suited for use in a photographic safelight.  The thing is, these lamps put out so much light that they are a danger to photographic printing papers.  If you look at the spectrum, you will also notice there are other wavelengths in the blue and near green that can cause fog.  A proper cutoff filter will remove them.

SOX Lamp Spectrum

Spectral output of SOX Lamp

Even with the greatest spectral output beyond the main sensitivity range of the papers, if you expose the paper to too much light you will get fog.  You have to attenuate the SOX lamp output even further.  I have made my own filters for my Thomas Duplex Super-Safelight and it is not that difficult, nor is it expensive.  I have another post on this BLOG that deals with the proper cutoff filter and using ND filters to tame down the light output.  You will find the post titled, “THOMAS DUPLEX SUPER SAFELIGHT FILTERS” contains the details of how to make your own B&W filters.

You will also note in this previous post that I have replaced the lamp in the Super-Safelight we use.  The stock unit comes with a 35 watt (SOX35) lamp, which in reality is way too much light for the small darkroom.  The thing is just way too bright for our darkroom which is 9 1/2 x 16 feet.  Realize that there is no practical way to electrically dim the lamp.  So, I did what I usually do with most everything around here; I looked to modify how it works.

Doing a little research I found that the smallest SOX lamp available was 18watts (SOX18).  That is what I wanted; less wattage; less light!  If you choose to do this, keep in mind that the ballast and capacitor are specific to the lamp.  If you want to change the lamp wattage, you have to purchase the appropriate ballast and capacitor.  If you are not comfortable working with electricity, please ask for help, or do not attempt this.  But, if you decided to move to the lower power lamp, there isn’t much to it.  You simply swap out the ballast, the capacitor and the lamp.

Ballast & Cap

SOX Magnetic Ballast & Capacitor

Using the SOX18 lamp will greatly decrease the light output of the Super-Safelight.  This coupled with the use of the proper cutoff filter and ND filters will allow you to tame the light output to a manageable level in the smaller darkroom.

NOTE:  One more thing; the stock Thomas Duplex Super-Safelight uses the older magnetic ballast and external capacitor.  This is what I used and this was near 20 years ago.  Now you can purchase an electronic version of the ballast but I have absolutely no experience with them, so you are on your own there.

Now you know how the Thomas Duplex Super-Safelight works, and hopefully how to best use it in your darkroom.  Do Not Forget to TEST to be sure your safelight is SAFE!



Lighted Easel

We work very hard out in the field exposing film to interesting and inspiring subjects that we believe we can turn into an acceptable finished photograph.  Next we hold our breath as we get a first look at the negative. . . same thing when we get a peek at the proof and later the first work print.  This continues through all of the refinements until we finally end up with a finished photograph.  Next we live with this image. . . and when we are finally satisfied with what we have created, it is time to show the print.

We love to show our finished photographs. . . to anyone that is willing to look.  The thing is, in order to really view a fine photograph, you have to light it correctly.  Looking at prints in a dark room, gathered around a table in a restaurant, or anywhere there is insufficient light, is not what should be done.  The problem is there is no easy way to properly light a photograph without hauling your own light.  This has been one of those things I have pondered for years.  The best I have ever done is to use an easel and a spotlight on a stand to illuminate sufficiently the photographs to be shown.  Even Edward Weston would get out his light when he showed his prints.  This is the correct way to show your photography.

The proper lighting of finished fine prints has been something I have agonized over for years.     As usual, when I am faced with trying to design something from scratch, I take a nap.  I do my best thinking when I am asleep.  This one took more than a nap.  I pondered this for quite a while, off and on for months.  Then one night I had a dream. . . there it was!

Bringing an idea to reality is not always an easy task.  Fortunately, I have been doing this for years and I have found that if I can imagine it, I can eventually build it.  The interesting thing about this project was I had most everything I needed laying around.  It was just a matter of putting it all together and making it work.

So, what am I talking about?  What I wanted was a simple, easy to transport, easy to assemble display easel with integrated light.  A single unit so I do not have to carry a wooden easel and a light with a separate stand.

As I said, we had most everything needed laying around the house.  We have several of these really nice aluminum tabletop easels.  There are several light stands in the closet, along with light fixtures and even a Manfrotto SuperClamp.  These items made up most of what I needed.

The bulk of the project required that I make a boom to hold the light fixture and come up with a way to mount the easel to the SuperClamp.  I machined a block of aluminum to hold the easel at a convenient angle and attach it to the SuperClamp.  I spun out a simple boom with a counterweight that attaches to the top of the light stand and is fully adjustable.  The SuperClamp, with mounted easel, is easily attached to the stand at any convenient height.  All that is needed is electricity for the lamp.  Presto. . . a complete, self-contained, lighted display easel.

The last piece of the puzzle was coming up with some convenient way to store and transport the lighted easel and its assorted parts.  There wasn’t much we could find off-the-shelf, so it was off to the garage to build a wooden carrying case.  Fortunately, there was enough scrap plywood on hand and it was just a matter of building the case and fitting the parts inside.  A little sanding, a few quick coats of varnish, some felt padding, hinge, handle, latches and the whole thing is ready for the road.

Now all we need is a captive audience!



SimplicitySeems everyone has their favorite method for exposing and developing film. You do shoot film, don’t you?  If not, you should!  But I digress for sure. . .  There are as many ways of working with film as there are opinions. . . maybe more.  None are better or worse than any other, if they work; if they give you the results you insist on within your own vision, then you are already there.    But, in this day and age there are a lot of people coming into photography and just now discovering film and the traditional darkroom.  In the beginning film is a mystery and requires some time to begin to master.  Of course, the most important thing is that you shoot film and make finished photographs.  How you get there is a very personal thing and you need to choose what works best for you.  But, you have to start somewhere.

For me, I prefer simplicity when I am out making photographs.  I do not want to get bogged down with a lot of complexity.  I struggled with film exposure and development, like I would speculate that most everyone has when they first start out trying to understand film photography.  It was way back in the mid 1970’s when I realized I could process and print my own photographs.  This was a big deal for me.  It started a lifetime involvement with photography and the wet darkroom.

I stumbled around, trying this and that looking for that magic technique that would give me a negative that would print what I saw in my mind’s eye in the finished print.  I read everything I could find on the subject.  I even toyed with the idea of becoming a strict Zone System practitioner.  Thing was, everything I looked into was just way too complicated.  There had to be a simpler way. . . at least, that is what I thought.

Somewhere in the 1980’s I discovered Fred Picker and his “Zone VI Workshop” book.  This was exactly what I was looking for.  It made sense and contained a simple approach that I found worked!  Having found someone that was also into simplicity, I subscribed to the Zone VI Newsletter.  I remember really getting excited when I discovered the latest issue in the mailbox.  Plenty of opinion and advice that really made sense.  To this day I still have my complete set of these newsletters.  About 25 years ago when I seriously decided to start working with large format photography, I read the entire set again. . . three times. . . every issue, #1 through #83.


I had experimented previously with what Fred called MPD (Maximum Printable Density) back in my early days in photography.  I had very good results, but I drifted away from the darkroom for a while to concentrate on a career.  When I moved back into photography after a brief hiatus,   I dove right into large format.  I needed to relearn my darkroom skills, at least to the point where I had left off and establish a sound working technique.

MPD is such a simple approach to exposing film that most think it will not work.  It is deceptively simple for sure!  I did some experimenting to get back into the groove and continue my experiments with simplicity.  I found that MPD was just what it claims to be. . . SIMPLE. . . and well-suited for any film format!   I am a big fan of ‘simple’ for sure.  As with anything, it is ludicrous to use something that does not work.  Why make it worse on yourself.  I approached MPD with the idea, that as long as it works, I will use it.

It is funny how there are things that just seem to fit you and continue to do so.  It has been over 25 years now and I still use MPD. Why?  Because it works!  My wife uses it and she is sold on the idea of simplicity also.  If you have seen any of our original prints from LF negatives, you have seen film exposed using MPD.

Oh, guess I forgot to mention exactly how simple MPD is in practical use.  Here goes, don’t blink;  1. Find your subject, compose as you wish.  Not much new there.  But, here it comes.  2. Meter the area you wish to render as a Zone VIII.  White painted wall, snow, sand. . . whatever you wish to print as finely textured white (Zone VIII).  Meter that area.  3. Open up three stops, or place the reading on Zone VIII if your meter has a Zone Dial.  4. Set your exposure and expose the film.

It is actually even easier than that;
1.  Meter
2.  Place VIII
3.  Expose. . .  DONE!

Now, don’t believe this is a haphazard way of working.  First, you must do your film testing.  You need to establish your working EI (Exposure Index) and your normal (N) developing time.  You need to establish a proper proofing regiment.  Your proper proofs are your control.  They tell you just how you are doing with film exposure and developing.  Study your proper proofs and make fine adjustments on the fly.  Thing is, once you find a starting point, things get much easier.  You do not have to engage in never-ending testing.  Test once. . . find that starting point.  As Fred Picker said, “Get one foot on a rock.”  Then you use your proper proofs for fine tuning and a constant check on how you are doing.  Simple!

The Film Exposure Work Book

Are you interested in making really good negatives?  Want to understand proper proofing,   personal film speed and developing times?  How about getting started using MPD?  Interested in getting the technical stuff behind you?

I was asked how to use MPD and what testing was necessary years ago.  I wrote “THE FILM EXPOSURE WORK BOOK” specifically for those interested in learning where to start.  This 44 page book is now available for download in e-book format from our online store.  You will learn how to establish your working EI.  Determine your N and N+1 1/2 developing times.  Proper Proofing is covered and much more.  You will also get a printable 12 page Work Sheet to record your testing results.

Is MPD right for you?  If you are just starting out with film, it just might be if you are interested in a simple, reliable method for making the best possible negatives.  Fred Picker had a large rubber stamp that said TRY IT.  He used it to answer letters people wrote to him asking questions.  You will only know if you TRY IT.  It has worked well here for over 25 years!

It has been a very busy start to 2015 for us here at Harlin Photography World Headquarters.  We returned from our annual trip out West the first week of January and have not had time to look up since.  We had a lot of film to process and thankfully, that is about done now.  Susan is already printing new film and JB is almost done proofing and filing.

One project we have wanted to tackle for several years now has been an upgrade to a more user-friendly, modern-look for our web site.    The site has been in continuous operation since 1999 and has gone through numerous upgrades over the years.  We have continually added more and more content, so it is no small task to rebuild a site that has this much subject matter, but it needed to be done.

We really wanted to start on this last year, but there just wasn’t enough time.  This year the web site project was moved to near the top of the list and it is finally a done deal!  JB has been hacking on WordPress code, off and on, since early January and has finally finished the site with a completely new look.  We have even moved to new web hosting for the delivery of the updated web site.

We have rebuilt all of the Snapshot Albums.  The Cole Weston Workshop album was completely rebuilt and the original photographs have all been rescanned.  The Articles and View Camera Project areas have been updated and revised.  JB and Susan each have new areas with updated galleries of their work.  We have updated the menu structure for easier navigation and access to content.  The entire site has a new look using a customized theme that we feel is much more pleasing, up to date and much easier to navigate.

We would like to invite everyone to stop by and take a look at our new web site. .

Always, thanks for your support!

JB & Susan
