Mamiya C330f, Kodak TX 400, Diafine 3+3, 120 Film, V500, Red Filter,
Okay I got a roll of Kodak TX 400 to spool in my Patterson plastic reel. Here it is!!
I don’t really like the results so far. But… There is a couple of things going on here that could have influenced the results I got.
First, its hella grainy!! I take back what I said about HP5+, this is way more grainy than that stuff. I cringe to put this up on Flickr because of how much sharpening they apply to the resized images. I’m sure it will look awful unless you click through to the large size. This is medium format for gods sake I should hardly be able to see any grain. I would not complain if it was a frame of 35mm but this big a negative, c’mon!
But wait a minute. I shot this at an EI of 1600! Pretty cool huh?. Geez you could probably shot this stuff at that speed in a night club with some fast glass. For an EI of 1600 I think this is more than acceptable. Although I have seen 35mm scans of TX at 1600 souped in Diafine and they were almost grainless.
Now here is the rub, I rated this at 1600 and shot with a red filter on, hence the cool contrast in the sky. The filter I was using had a 8x filter factor which I believe is 3 stops(please correct me if I’m wrong). So I set my ISO on my meter at 200. 3 stops brighter than 1600. My negatives are very dark and that means that the image when inverted in the computer will be very light. So right now with out further testing I have to assume that something is not right with using the filters recommended compensation factor with this film. On a side not my math work out wonderfully with HP5. In Diafine Hp5 has an exposure index of 800, and that means set your meters ISO to 100 using this filter (correct?). And it worked more than well. I barely had to touch the files after scanning. Now I admit that I don’t have the best scanner in the world (Epson V500) and I have not shot a lot of 400 speed film but I have seen what can be done and this result is far from it. I have also scanned 100 speed film and processed it with fairly poor post processing sharpening and still had a grain less film and retained the wonderful dimensionality that film offers. Besides I have shot 400 speed 35mm color film and there is less grain in it than this. I firmly believe its because I had to mess with the file too much in post to get it to the levels I want it.
HP5 may be my goto film for the red filter, thought I will try the TX at an EI of say 800 or maybe even 1600 for a shot just to see how it reacts with Diafine. Seems to me that the image is over exposed (correct?). A dense neg = over exposure, I believe. Would love to know what anyone else thinks. I am also going to have to try some FP4 with the red filter and also all of these with some Ilfosol 3 as well.
