Thanks. I was to shoot folks at the event today and planned to use different filters to experiment, but being outdoors - whole thing was canned due people being scared of wee bit of chill.. meh.. :( But i remember about request and will try to do it at some point, at least for deep green/orange/light yellow-green and of course without.

(didnt get to experiment on this one, b/c getting my mother in front of camera is whole adventure and then i couldnt really tell her "oh , by the way, let me check it out how all those guys will work on you and post it on web" - she would kill me :))

I have a box of the Fuji HR-T but only developed two sheets so far. I am wondering about Diafine with this film but it has been so grey in Tennessee that the sun hardly comes out. Both of your portraits show great detail. Anyway, thanks to all sharing their findings.

That portrait of Marsha is cool. Love the tree limbs' focus at the top. I assume this is Rodinal also?

Thanks,
Mark

Yep... I am simple man and sticking to single developer - Rodinal formula at different dillutions :) Tried to wade away with other ones, but kinda didnt like results all that much with ID11 and others, on other films.. So i am just sticking to one.. (that said i still got unopened pack of HC110 :)).

Oh I dont get all bitchy about critique either, Mark, no worries.. I am always trying to learn things from people, and this forum is great wealth of information . I never been truly trained on whole dark room part of photography - back in days i didnt have much choice for film and developers nor money to experiment. Now that i am coming back after years of shooting and processing in lab or just shooting digital - i do discover new chemicals and whole bunch of tricks that people use, and i am just in awe of people who can actually figure this stuff out :)

This was actually shot on overcast day, so sky here were gray as it gets at 11am-12pm on typical rainy day in texas. So it might be point of reference, kinda.

Btw, what makes me curious is if there is different response in Fuji and Kodak films..

Kodal Mammography film in a mammography cassette

135KV / 3ma 4 seconds ;)

Impatient man that I am (The thought of processing one sheet at a time in order to minimize scratching makes me cringe) I made some spacers out of a thin plastic mesh material to lay in between 4 sheets of 8X10 Xray film processed in a 10X12" tray. I normally process 4 to 6 sheets at a time using the shuffle method of agitation. This time I just rocked the tray, alternating from each side.
Anyway...it didn't work. I did minimize the scratching, but the trade off was some nasty uneven development in the areas where the film contacted the spacers :(

Randy, tanks and four at a time. It is a wonderful thing.

I bet. Just trying to work with what I have at the moment. Just don't want to (read - can't afford to) spend the money on tanks and hangers. Guess I could make a tank...?

I did try processing in a Unicolor drum recently - 2 8X10 sheets at a time. Used very little chems (150ml) and minimal scratching. That is an option.

Randy, what happened to the emulsion on the other side when developing in a tank?

depends on tank, afaik

In jobo print ones it goes dead. In unidrum ribs are present that do lift film a bit from walls , so both side on negative do develop in full.

Andreios, you mean drum? I have not processed in a dip & dunk tank, just tray and rottery drum, and as Sergie said, my drums have ribs but they had very little if any effect on the image processing. The film seems to process evenly on both sides.

Great idea, as one who has baulked at the price of 8x10 B+W, I may well give it a go, Some of the above don't look different to results I'm getting with Fomapan 100 in 8x10
