I would appreciate suggestions on lighting for macro work. Do have Nikkor 105 micro lense but when I use the flash the contrast to too extreme. Light is just too harsh and distracts from main subject. Any suggestions or reference to books or articles will be appreciated.
from what i have read it is a by guess and by gosh process. bracketting exposures +/- 2 stops either way is advisable. the first thing i would do is make sure your processor will do it for you. some may not for fear of contamination.
It also depends on the film you are using and the chemical you are using. I was told by my photo lab the fuji and kodak c-41 chemicals will do different things to different films.
The only real way to know is to experiment. For $15 investiment you might get some great pictures or maybe not. Either way you will learn something.
The most common use of cross processing is developing slide film as a negative. It can lead to some very dramatic prints, or projection transparancies in negative format.Overexposing slightly will give more dramatic (saturated) results.
Processing print film as a slide--E6-- is not as effective since the orange mask is built onto the film base. It will however, make some stunning prints.In this case, slight underexposure will give better saturation, just as in actual slide film.
P.S. If you have some slide film that is cross processed, and wish to make "normal" prints, I recommend that you scan the "negs" as a positive, and then reverse it in Photoshop.
I have experience of doing cross processing from Fuji Sensia II 100 to negatives. I rate it at 50 iso and still not enough because the drastic increase in contrast make my subjects hidden in shadows.
