Halation can be a good thing.
Wayne,
Imagine three or four of those film hangers in the picture nested on top of each other laying in a tray. Pick them all up, shuffle order, put the stack back in the tray. You get all the agitation and sloshing action in the shuffle. The film is secure in each hanger with a separation between each sheet about the thickness of the hanger... I can try to put together a picture or two if it would help.

As addition i might say that actually anti-hallation backing was also made before invention of film, on glass plates. However it was quite expensive in comparition.
No problem! Thanks!Quote:

Fuzzy edges or entire rings around very light objects. If you type "halation" in google images you will get some nice examples.Quote:

Of course nowdays people shoot IR and getting it back :)
This end of my project is near....

Student Portraits Exhibit Poster by Lee Smathers, on Flickr
Congratz, Lee :) Well done.
Looks great Lee! A big project for sure! I know students you may be busy for a lifetime. Good job!
Thanks guys. I haven't been posting here because I've been doing (I just counted 55) portraits. It's been a 30 hour a week part-time job for the past 4 months. Developing in trays was nuts. I finally took Jim's advice and got 3 tanks and 8 hangars. It works perfectly. 8 negatives (two batches of 4) is great for the 1 gallon of Rodinal 1:50. After that my images start to loose contrast. I should probably get another gallon tank or two for pre wash and rinse. Right now I'm using plastic kimchee tupperwares. It's perfect width but too long. It holds probably 3 gallons of water. But it works.
These are 15 of the better ones. 55 portraits! That was a hellofa project. I won't be doing this again in this magnitude. Perhaps only one class of 20-30 students vs. 50-60 students. I'll post some pictures of the gallery set up. 50 8x10 contact prints and 4 super sized 1 meter x 1.2 meter enlargements of the best of the best just to see how well these things enlarge with my digital work flow capabilities. I may do xray landscapes with 7x17 or 8x10 which will most likely be digital output.
Great photos!Quote:

Lee, Congratulations! Great project and I'm glad you got the tanks and made your life easier!I have not forgotten you. Just been very busy. Eventually you will have something to show your students.
I do think tanks may be the best.
Tonight I will try 8X10 tanks for the first time. Been practicing film hanger loading, I expect scratches...
My 4X5 tank set up is wonderful, but obviously 1/4 scale and so much easier in every way. Loading, and unloading zone...Fireside Theatre, for those that remember.
Lee: Great project, excellent poster, best of luck with the exhibit! While slightly off topic, the poster proves to me the truth in a trite stereotype: to most of us, the "other" looks very much alike. Because you have made each portrait similar in lighting, pose, and scale, my first response was "wow, at least three or four of your students look so similar that I would confuse them in real life."
Alan, It's green sensitive xray.
Jim, awesome!!!
Randy, they're super easy with a safelight. I haven't gotten any scratches, but sometimes a little bit over developing in the areas that hold the film. Usually it's where the unexposed area is from the film holder, so it's no big deal. I can see it in some of my contact prints. I think it's part of the process that makes it so imperfect and more "truthful" than digital photography. I can't imagine doing tanks and hangars for panchromatic film though.
Peter, I have students that are watching me in the darkroom and say "oh it's me" or "it's xxxx" and I'm like, "no it's xxxx." Haha. Our TA, Changhwan, also said "Koreans are too similar". I used to think that way too, but after living here 12 years, I am able to see everyone is different. Black and white helps to really uniform the faces more and perhaps blend them.
I started this project to get my students interested in analog again, experimenting with other mediums (xray, Rodinal, Foma papers, homemade developers and toners), and large format. Many of my students buy an EOS 5 or other automatic film camera to use with their DSLR lenses so the look of the photography is similar. Many don't use prime lenses and only zooms. If I was doing photography like that, I'd get bored of analog and not see any advantages over digital. There is a wealth of history with analog cameras. My 100 year old Korona and 100 year old Dagor 12" give surprisingly great results to them. The students also only know Kodak films, D-76 and Dektol, and Ilford papers. Even some have asked, "does Ilford still make film?"
I came to this university hoping to teach digital and portrait photography, but those classes were already taken. When I was assigned to teach B&W and Editorial I was determined that I would make them my classes. I'm really glad they assigned me these classes! I've finally been able to find photography I enjoy again! That's really important to me. I don't want to be a zombie photographer.
So there's no hidden meaning to the photography. I'm just taking pictures. Others can evaluate it all they want.
Nice post Lee.
Yes, under safe light even I can load 8X10, but I am hoping to do 'real' film also. Kidding about 'real'.
I like your project!
Well done! We look forward to a digital gallery image.
Six sheets or so into the Agfa SG

Having some fun with a big ole Bausch and Lomb soft focus dialed full fuzz. 16" f/4.5 wide open.
Charming shot. And the model is quite a charmer too.Quote:

Experimenting with light and filters with this single sided kodak film. This is with a green and a yellow filter.
that reminds me .. i need to order new supply of film soon, so it would arrive when i am back to Dallas ;)
What ISO speed are you rating this film?
I was unaware of this film.
Thanks!

I found a couple sources, it is more than double the price of Kodak double side CSG.
I am going to get a box.
Single sided will be better, i am a bit rough with my film, scratches...
Thanks for the tip!

I have been using Kodak CSG.

11x14 Giclee print, printed on Epson Hot press paper and toned to matched my Platinum print so I called Platinum Giclee print.
The 18 In Verito was used here , 2 stop down for exposure.
Hope you like it!

Randy, come on now! Slow down and be careful. You can see in the red light. Don't drag the film over the flap when you load and unload and just be careful. Save the money! I hope you don't scratch regular traditional film?
Thanks Gents, I'm glad that you liked it.
Jim, KIIS is the way to go. I wonder if people have ever noticed that 90% of my image posted here for all this time are Xray film using straight D76 as the developer.
Yes Jim!
And, you are correct the scratches come from the flap of the holder. Took me awhile to figure that out. :)
I don't scratch normal film.
My DIY 11X14 holder is very gentle, with it's acrylic slots and no flap. Studio only.
Jim, have you tried the high priced SS X-Ray? It even has a notch!

You are quite welcome Randy. I didn't know that you are also looking for some recipe too .
I have 300 sheets and I have only just begun...
Today I am going to buy a new chest freezer.
I see TT buys only enough for 2 years, so he does not need to preserve it.
But I am sure we all are worried about the demise of X-Ray film...

I just received a box of 5x7 today and the film is just a tiny bit too large to fit properly in my holder (this is for a thus far infrequently used pinhole camera, so yes, I only have one holder!). The holder is a older Lisco one and I am wondering if this just happens to be an example with a tighter fit.
Does anyone have any experience to suggest I should just take a chance and purchase another 5x7 holder, or if I need a 13x18cm holder. My only local source has no holder of these sizes, otherwise I'd check it out firsthand. Thanks.
8x10 an 11X14 X RAY film is 1/16 shorter than nominal in both directions and fits regular holders.
.
Measure your film and see if it is 1/16 short, but I doubt it.
It's most likely not your holders, but the film.
Very carefully and gently cut it to fit. Under red light.
Good luck!

I have used Fuji 8x10 and it fit fine in my 8x10 holders. The 5x7 is rebranded Agfa I believe.
I guess I can either trim it every time I load it or hunt for a 13x18 holder.
Since 5x7 inches is 12.7cm x 17.78, a 13x18 holder would work, right? Or are they slightly smaller too?
I don't know anything about the actual size of 13X18.

I just got in some 8x10 blue-sensitive to cut down to 4x5 and whole plate. Can I just use scissors to cut it? I have a rotary- you're trimmer that I use to cut paper but I am scared that the pressure exerted by the trimmer to hold the film in place will scratch it. Also, any tools on losing threes film? Besides, of course, not dragging it along the flap :)
Could you please tell us which film you are using and the exact dimensions?
I would love to find X RAY 5X7 that fits regular holders.
