It is most definitely understaturated, but not too bad compared with sRGB (larger everywhere except on the yellow side of things). I think the M8 is going to be a perfect match for it, once the colour response of the camera is figured outīut I think the whole problem here is that you've been looking at the V1 profile while in conversations with Asher in other places I've been using something called the "chrome" profile.Īnd thanks very much for your clarification your analysis of blue vs blue-green response in the original V1 profile, compared with aRGB-along with limited red curve-is exactly what I'd expect from that initial profile, and exactly what I see from PM5 graphs too.īut this reflects more on my ability to create C1 profiles than on the camera or sensor response, I thinkĪs some background, that JHR V1 M8 profile was just a ridiculously fast attempt to 1) correct the (IMO) awful original C1 M8 profile in terms of LAB values for the test patches I could measure, and under tungsten light to boot 2) Map out the magenta cast to black synthetic as an immediate workaround. It's the most promising RAW converter I've seen to date (though I'd kill to have a way to quickly set BP and WP like a curves / levels control-as well as the zone control for fine tuning).
What the 2d plot doesn't show is that at certain points the aRGB profile is actually larger-it's not completely contained.įirst-thanks a million for LightZone. As I think Michael Reichmann said in his review, this probably doesn't really mean that much, but here it is FWIW. Then I soft-proofed the results to sRGB in Photoshop, and almost half the file-all saturated reds and blues-were outside of sRGB gamut.Įven more certainly, the profile isn't clipping the camera response! Gretag Macbeth Profile Maker 5 reports that the resulting tweaked profile I've been using is actually actually bigger than Adobe RGB-let alone sRGB-particularly in saturated blues. Just to test this, I developed a couple of shots from my last engagement shoot with C1 and the chrome profile I've been playing with. Again, blues are a dead giveaway in my experience. Having said all that, I don't think shots I've been taking fall within sRGB for the most part. We need new profiles to go with the IR filters, is my feeling. So I don't have any sense whatever about the resulting colour gamut of tweaked profiles + IR cut filters.
So far, the profiles I've tweaked are meant to work around NOT having filters, which, since I can't find them anywhere to buy, I don't have anyway right now.
There are no profiles, to my knowledge, that take advantage of the IR filters yet. What is the repected RAW developer saying? That the C1 profiles are doing this? Or that the IR filters are doing this? I'd love to know the gist of what he or she means by this. That's very odd-my feel for this is that sRGB isn't nearly capable of handling the calculated color gamut, though I'd truly bow to other's expertise here.
