Thanks for the info, I'll keep that in mind next time I submit a print of the "red channel" for a galleries show. I suspect galleries will start hanging "red channel" shots right after they begin accepting DxO curve prints.This is very wide claim that can be viewed from different angles of view. From what I´ve seen, there is SOME noise in this part, but also it is clearly able (or my eye if I look at the output) to differentiate noise and detail. There is lots of detail there.
Well it's a claim supported by a grey gradation of the red channel that starts to fall apart at 36%.
Personally, I think the Canon red channel is horrible frankly. Losing detail that early in the tonal range is not acceptable to me.
If you're ok with that then that's fine. I've put the info up there, and that's all I can do.
Seriously, all of your Guitar shots look pretty nice and all seem to be acceptable -- I understand the nit picking and the relentless drive toward perfection but you have to admit that thousands of commercial photographers shoot this sort of thing day-in and day-out and somehow make nice images. This whole discussion seems a bit silly IMO.
