MEASURING PAPER FOG
I was recently asked to test some Kentmere paper for fogging. A friend had shut down his wet darkroom and had several packages of paper he wanted to sell, but wanted to know if it was still useable. I agreed to test for him and if you wonder how to check for paper fog, here is the process I use.
Begin by cutting off a strip of the paper to be tested in very subdued safelight to total darkness. Since the paper I was testing was 16×20, I cut off a strip across the short side about two inches wide. I then cut the strip in half. This gave me two pieces of paper 2×8 inches. On the back of the paper I mark one with the letter ‘F’ and the other with the letter ‘D’ and place the latter into a light-tight box.
The strip marked ‘F’ is placed into a tray of fresh fixer and agitated for five minutes. Then it is placed in a tray of running water. Next the strip marked ‘D’ is placed into a tray of developer, agitated for two minutes. . . stop for thirty seconds. . . and fixed for five minutes. I use my standard print developing chemicals and the normal times. If you use different materials, use your normal times. Once both strips are in the wash tray, turn on the lights and wash for thirty minutes. Remove the test strips and dry as usual.
What has happened here is I have cleared the test strip marked with the ‘F’ which stands for fixed only and I have developed the strip marked ‘D’ for developer as usual. All that is needed now is to measure the reflected difference. I used an X-Rite 810 densitometer to measure the difference and found it to only be about 0.003, which is nothing to worry about. Keep in mind that all light sensitive materials, film or paper, will have some amount of base fog when developed.
Fortunately I was able to report to my friend that his paper was in excellent condition and he was happy to be able to sell it to another photographer. Hopefully this batch of paper will live on to produce some beautiful prints.
Also keep in mind that you do not need a densitometer to run this test. If you cannot see any appreciable difference in the two test strips, you can assume the paper is in good condition. If you have some old paper that shows signs of fogging, you can experiment with adding a restrainer, like Benzotriazol, to your developer to see if it will help. Never throw out printing paper just because you have had it on the shelf for some time. Test it first. . . you may be surprised to find that it is in good condition and useable.

DFW LF GROUP, WET PLATE CAMERAS WITH TY GUILLORY, Saturday, August 20, 2011
On Saturday, August 20 we will head east to meet Ty Guillory on his ranch in Mineola, Texas. Ty is one of only two craftsmen still handcrafting traditional wet plate cameras. Although there will not be time to see him mix the chemicals and prepare the plates, we will see how the camera is used to capture a couple of images and how the plates are then developed and varnished.
Once the demo is done, we will spend time in the workshop learning about the wet plate camera, we will enjoy burgers and hot dogs, and then have an opportunity to photograph on Ty’s 25 acre property. Ty would love some of us to photograph his family on Large Format as this has never been done before. Consider this our contribution to a fun-filled outing.
Ty’s cameras are historically correct, built from plans from the George Eastman House Museum of Photography. Many of us saw the story a few months ago about Ty and his studio on Texas Country Reporter and this should be a very interesting trip.
Mineola is about 2-1/4 hours east of Fort Worth, 1-1/2 hours from Dallas on US 80. We are limited to 12 photographers due to the size of the studio where Ty builds his cameras. Please RSVP by e-mailing Michael directly at: michael@kan.com.
As soon as we reach 12 participants, he will place additional names on a waiting list in case there are any cancellations. Again, RSVP only through e-mail! Directions (and caravan point of departure for those who want to ride in a group) will be e-mailed to you closer to August 20th.
Here are some great videos of photographer Luther Gerlach practicing the art of wet plate photography:

Looking forward to another great outing!

DFW LF GROUP, MUSEUM OF THE AMERICAN RAILROAD GATHERING, Saturday, July 02, 2011
Though not exactly posted here in order, the D/FW LF Group, by popular request, has added more summer events. The Dallas Museum of the American Railroad, located in Fair Park, will open their doors a bit early this July 2nd morning to allow our big cameras in for some peaceful photography. Once the doors open at 10, we will still be able to take our time to take photos, but there might be foot traffic between you and your object!
The museum is located at Gate 3 in Fair Park. We can begin entering the premises at 9AM.
A couple of things to consider:
1. Everyone will need to sign a standard waiver stating that the photos will not be used for commercial purposes.
2. There is a $7 admission fee. Since they are opening the doors a bit early and have additional costs involved with this, We am asking you to make an additional contribution to the museum. This can be any amount you feel comfortable with; it is just a friendly gesture of thanks to the museum.
We are planning to have lunch at an old Dallas Deep Ellum restaurant after the shoot, so save your appetite for more good food. Adairs has been around for a long time and has a great rustic(?) ambience.
For more continuing information, drop by the Large Format Photography Forum.
See you on July 2. . . and. . . do not forget we are heading to Pilot Point July 30th.

DFW LF GROUP, PILOT POINT GATHERING, Saturday, July 30, 2011
Here we go again! Our informal LF Photography Group is holding another outing, and even braving the heat of summer in Texas.
Visit historic downtown Pilot Point for some great photo opportunities; both architectural as well as close-up detail of antiques and antique fixtures.
Since it is the midst of summer, we will meet early in the morning – 7:30AM. Color film photographers might want to be there even earlier! Sunrise will be at 6:39! Complete side lighting right down W. Main Street will be at 9:17AM. This might provide for some interesting shadows! There are some wonderful murals to photograph also. Google “Bare Nekkid Ladies in Pilot Point” to read up on the most controversial mural in town! The bank building, just off the square, was used in the movie “Bonnie & Clyde.” Many photographic opportunities are within 2 blocks on each side of the town square.
We will end with brunch at the local greasy-spoon on the town square between 10:30 and 11. This should help us beat the worst summer heat and humidity!
Estimated drive times from:
Ft. Worth: 1 hr, 10 min
Dallas: 1 hr, 15 min.
Carrollton – 55 min.
We invite everyone interested in LF & ULF photography to join us for some serious discussion and fun. Also, if you are a working photographer, please bring a few photos to share with everyone.

Hope to see you July 30th in Pilot Point!

D/FW LF GROUP & TCC GATHERING. . . A GREAT TIME!
What a great time we had Saturday with the D/FW LF Group & Tarrant County College, Exposure Photo Club gathering at the TCC N/E Campus. We had about 25 enthusiastic participants, ranging from beginners to somewhat seasoned photographer-types in attendance, and everyone had a great time sharing stories, showing off their equipment, and photographs. The weather cooperated, it was dry, cloudy, and the temperature was pleasant.
We packed up our outing on the campus grounds after a lot of looking, touching, and photographic talk, then continued with more discussion over BBQ at North Main BBQ in Euless. The truth of the matter is, for those that are interested, you just can’t get enough photography! And, there is a rumor that the D/FW LF Group is planning more outings for the rest of this year and into next year.
Stay tuned here for more announcements and to keep up with the local happenings. Our goal is to promote film photography, in any and all formats. . . though our main focus is LF and ULF, if you shoot film of any size, or if you are interested in film, please join us to learn more. Everyone is welcome. Our goal is to promote photography, in any and all forms, and to dispelled the myth that film is dead.
We would like to thank all of those involved in the planning of this event and an even bigger THANK YOU to those that attended. We are looking forward to seeing everyone again soon.
