No presoak, no stop? = No more answers to futile questions when things don't come out consistently!
How can I get a balanced photo with good whites if the borders are not pristine? The 70 degree tray method is producing pristine white borders. Something is causing it.
There is also something else going on here. I found something interesting last night while comparing the "pro lab" print to mine. I can NEVER get my whites as white as the pro lab.....the border is not as white on my prints!!! I turned over the pro lab print and it is the SAME paper! Fuji crystal archive. All of my prints just have a slightly darker border. My easel masked it but the process is doing something. It is on all dozen or so prints. Slightly beige. THEN, I said to myself..what is with this tray processing I hear about...never did it with color? So I attempted to try that at 70 degrees. I did 2 prints....one at 2 minute, and one at 3 minute because I was not sure what the dev time should be. The results where nearly identical....really, really close to the point it was a non issue. So I used the 2 minute developing time. BUT GUESS WHAT? All borders on the tray prints at low developing temp where pristine virgin white! Same paper! And it is brand new. I wonder if it is the process...the tray was developer to blix...that's it... JOBO is 100 degree 30 second prewash then 1 min dev, then 30 second Kodak indicator stop bath then 30 second wash, and 1 minute blix. all solutions in tray are 500ml, jobo I use 200ml in the tank that is meant for 1 11x14 or 2 8x10, but I only do 1 8x10 at a time right now. I am an electronics engineer so I know the importance of consistency. All jobo temps are 100 degrees 1 minute and drain last 10 seconds.
I like the tray processing since borders are ultra white. One thing I noticed is that my colors don't seem to pop. They always seem like they are a bit old and dull. everything is new.
- lab vs. own prints: lab prints from scans are usually boosted in color before printing, so they do not make a good reference point
Some food for thoughts:
- general: 60s @100 F is out of spec for RA4; spec is 45s @ 95 F, better stick too it; also, make sure you understand how temperature control works on the CPE2: Your actual processing temperature is the stabilized temperature of the processing liquids in the small clear plastic graduates; the temperature of either the water jacket, the 600ml storage bottles or the temp setting of the knob on the control panel can be several degrees off your actual processing temperature and is irrelevant; adequate pre-heat of the drum is of course necessary
- borders: you might have some sort very subtle light induced or paper age related fogging problem that does not show in tray processing because you are underdeveloping ever so slightly (without knowing), but shows when you "overdevelop" in the Jobo for 60s @100 F
- borders: I assume the tray vs. drum comparison wasn't done on the same day, so again look for any differences in outside factors that may have contributed
- borders: Kodak EP paper has slightly duller whites than Fuji CA, so do not compare different brands of paper
- lab vs. own prints: There are several varities of Fuji CA, the one you use might not be the same as the one your lab uses
- lab vs. own prints: lab prints from scans are usually boosted in color before printing, so they do not make a good reference point
