    For LF, specially for 8x10, it's interesting controlling well your process.

    I'd suggest you next books: Darkroom Cookbook , Beyond the Zone System, very cheap used.

    I'd also suggest you practice with roll film, you will learn easier (and cheaper) to meter from bracketings. All this would help you to progress faster both in analog process and in LF.


    IMHO mastering all that it's about learning some theory and practicing. The theory vs practice balance is a personal choice, but sure that learning well the basic theory helps the practical learning.

    Re: help developing problems 8x10 - WITH PICTURES.

    There's a lot going on here. I'll try to take it in order.

    Exposure: your negatives look underexposed. If you made a 10 second exposure and didn't adjust for reciprocity failure, you'd have underexposed your negatives. Ilford has charts in their tech sheets with all the info you need. Do your homework. Also check your metering, film speed setting, etc.

    Negative development: Use a standard developer with the manufacturer's recommended time for the film you are using for a starting point. Be careful and precise mixing chemicals. If you are not 100% familiar with the whole process from beginning to end and the specifics of the chemistry you are using, read up. Do make sure you fix properly.

    Print development: 30-50 seconds is on the short side even for RC paper. Again read up... Your prints look underexposed and underdeveloped.

    Here's a good and low-tech process check. Print a negative (make a test strip) so that the clear area on the negative is just barely distinguishable from maximum paper black (paper exposed to room light and developed for the proper time in properly-mixed fresh chemistry will give you a base line). Then, make a whole print of a negative at the exposure that gives you the black you want. This is a "proper proof." Evaluating it will tell you what's wrong with your process. No shadow detail in the print = underexposed negative. Not enough contrast in the print = underdeveloped negative. And vice-versa for both the above.

    Bottom line: it seems you need to learn a bit more and become more familiar with the process in general and what you are trying to do in particular. It's not rocket science, but you do have to embrace the learning curve and pay your dues (and read the instructions...).

    Best,

    These responses are incredible. I meant 30-50 seconds for developing the negative and I agree the water could've and should've been warmer. Will purchase the used books mentioned and run some specific tests before developing the next round of film. ... I think having accidentally burned the first two actual pieces of film black by thinking I could work in safelight (having been many years since in darkrooms), I was terrified to destroy any more photos "overprocessing." Better to have a light image than none at all. As recommended, a lot of careful testing / approach is in order.

    These responses are all very clear and amazing. Unexpected. Thank you all... over the world.

    Are you both referring to negative or print? The negative is definitely very thin. Ty.

    Negative or print? Thank you.

    The most important thing I think is the failure in developing the negative... possibly the reciprocity failure, noone mentioned I'm using the wrong chemicals so I suppose they are good. Will be purchasing the books and some negative film solely to learn.

    It's the time for developing a Ilford Delta 100 negative in Rodinal/R09 1+50

    No much reciprocity failure in your case, but remember that Rodinal is not a full speed developer, you have an speed loss of 1/3 to 2/3 stop.

    Perhaps it's better to start with D-76 or Xtol, because you have full box speed and some compensating effect. Then in the future you may try with other developers to find what you like. You may want the Rodinal character, but I'd I start with D-76 or Xtol, or with ilford equivalents, some are liquid and convenient.

    Read Horenstein on Basic Photography and learn to tell the difference in underexposure compared to underdevelopment. This will help a lot as you move forward.
