Digital is much more convenient and instantaneous than traditional film in a multitude of ways and one such convenience is the ability to adjust your light sensitivity on the fly, I'm referring to ISO. With film you purchase film stock based on your needs and hope that it will work for the lighting conditions during your session.
I have shot several rolls of Black and White film and pushed them by two or three stops above their rated value, but wasn't happy with the results, too grainy and contrasty, which was caused by the developer and developing process ( See above to photos).
Recently I purchased Adox Rodinal and went back to Stainless Steel tanks and reels to utilize and older process known as Stand Development. The usual development method I to continuously invert the tank slowly the first minute and then 10 seconds every minute until the recommended time is achieved.
With Stand Development, I pre-wash the film, then once the developer is poured in continuously invert or 30 seconds and let is stand for 15 to 30 minutes, depending on the number of stops the film was pushed and the ratio of develop to distilled water, invert four times and then let stand until the recommended time is reached. The rest of the process remains the same.
As you can see, there's a huge difference in the quality of the image. Both Color Negative (C-41) film and Slide film(E-6) can be Pushed, but the process involves only extending the development time based on the number of stops. Please see my previous post where I pushed CineStill 800 to ISO 3200 Funding Film
