Re: Rodenstock 28mm HR VS Schneider Super Digitar 28XL
So a little workaround since I shot kind of early in the morning the LCC are very warm and hard to tell the magenta cast in the SK and Banding in the Rodie. So I corrected one of the LCC and copied the WB settings than went back reset it and applied the correct WB numbers to all the LCC and applied and that is what you will see here. Once i correct each LCC those same numbers will be applied to the image. This trick was for you to be able to see the falloff and color casts in each setting. I also applied a small watermark to each so we know exactly which is which. NOW the GOOD news here and this was from the other day and i want to make this very clear again. The tech. analyze tool in C1 corrected every setting perfectly even on a 20mm movement which was riddled with a magenta cast. Before this new tool was made you could not fix that. This is great news since basically for IQ 160 users we can maybe get away without a CF filter. On IQ 180 which we all know is worse on the 5.2 micron sensor and the extreme pixel angle the magenta cast bleeds much worse. What the IQ 180 users need to figure out here first of all which one is best for you and do you need a CF. I think the answer will be Rodie and CF and we can certainly talk about this but for instance this magenta cast on the SK will be much worse on the IQ 180 given each movement and it will put more strain on the LCC correction to make the LCC settings applied to the image to be on target. IQ 160 and most Leaf backs may not have this issue and we will see if the corrected LCC are good through the whole frame and see if we need a CF or not with the SK 28. So these are things we need to look at going in this test.
The issue here with putting strain on the LCC to correct heavy falloff is it can introduce noise in the corners of the frame since it maybe correcting several stops of exposure. If this happens within the 7 or 8mm of rise that we speculate here on this lens with movements than you will need a Center Filter. So lets see what happens here.
