I've been doing some tests for about two years now... mostly with Kodak with some Fuji for comparison... Grain at pushed speeds depends on your treatment of the film.. exposure and processing time. I have found much success at EI2000 and pushed 2 stops in processor (Hope C-0508V, Kodak C-41 chems)... times in dev as follows: +1 Stops---> 262 sec. +2 Stops---> 363 sec. At higher speeds the film will tend to lose some actuance... and will react adversely under fluorescent and incandecent light... but that's where we like to shoot it, right?... so... I've been using the Ektamax B/W paper in our RA machine with favorable results... Although it isn't a 'true' black and white paper or process, it uses all of the information on the neg to turn colors into tones. This also works with Panalure, tray process B/W paper balanced for CLR negs. (neither offer extensive tonal control over +/- 1 to 1 1/2 grades contrast) I have also color corrected for the red/yellow shift under incand. with marginal results at EI2000.. better results at EI1200 (not 1600). Same results from fluorescent. Please keep in mind that OVER exposure and slight OVER development of CLR Neg. helps to control grain.. as the exposure/dev helps blend the dye together while dropping out silver, thus reducing grain. As for scans: Pushed EI2000 and EI1200 may show a green cast in shadow areas. This may be compensated for in PS by despeckling the Green layer or by curving out the green layer, thus reducing the green. Color balancing should be done with as much care as possible as to not remove any information from the file: such as using Levels or slight curve adjustments to each layer and not the color balance tool. Desaturating the green is another option, selection of the offending green portions of the photo and desaturating using Hue/Saturation or Selective color. Selective color will give more control over the amount of total colors in once channel (RGB or CYMK) thus may give a more natural looking color balance beyond basic Levels and Curves. The key is exposure and development... it may be difficult to find custom labs willing to process at certain times or temps.. but you can still control the exposure if you're going to scan or print at home... so get friendly with some lab rats and expose according to the best results from their +1 or +2 development times.. you may only realistically get +1 1/2 or +1 development from a commercial lab... results may vary.... or better yet.. buddy up with PJ type w/' access to C-41 custom processing! hope this helps!!!
