ASP colour profiles less bright than B5

[ferdinand-paris]

I started to do a major project in ASP and stopped because of the tiling bugs. I reverted to B5. I had to redo a number of images, and I noticed how much brighter they were at default settings in B5 than in ASP. A lot of the discussion about the new colour profiles has been the improvements in colour for Canon cameras. I'm using a Nikon (D700), and what I notice most of all is the change in average brightness. It varies from image to image, but for some images the difference is quite marked. The B5 rendition is a lot brighter. Anyone else noticed this?

Yes, all cameras got reprofiled for ASP, so that is to be expected. personally, my Canon 7d is now spot on with what the in camera processing gives. B5 was always slightly brighter

[ferdinand-paris]

I know all cameras were reprofiled. That's required by a new CMS. I guess I was expecting the main impact to be colour rendition, rather than the tone curve. That said, I have commented in the past that I felt that B5 was bright, and didn't get a lot of support on the forum, so I thought it was just me and my camera.

I'm still interested in hearing from Nikon owners about their impressions. I wouldn't use the term "slightly brighter" for many of my images in B5 compared with ASP.

p.s. This is not a complaint about ASP - I'm just looking to understand the new profiles better.

ASP feels slightly brighter than B5 for my D700 stuff.
Also my Oly XZ-1

Same with my D700's. However, I noticed that all the data in the high-lights are there. Nothing being clipped. Of course, this is considering that the camera's CSM are tuned for a nice medium gray (we are all aware that this body's meter is not factory calibrated for 18% gray but overexposes quite a lot).
I find ASP doing a good job with high-lights. But it's true that I must tweak a little bit more the curves in ASP than in B5 for a good tone balance.

Cheers.

It wasn't clear whether tundraquad is saying the same as me or as afx, but given the flow in the forum I suspect that he meant the same as afx. This really stumps me as to why different examples of the same camera behave so differently. I keep rechecking this on sample images in a large batch I'm processing at present, and B5 is consistently brighter.

I have exactly the opposite problem than ferdinand-paris': I see myself reaching more for the exposure and HR sliders, principally when I process pictures that have been shoot on overcast days with my Sony A700.

Also, I see over-saturation when opening JPEG files both from Konica-Minolta's Maxxum 5D and Sony A700 - up to the point that I have to turn the saturation slider in these cases to -30 in order to obtain a "normal" look.

Hi ferdinand-paris,

Sorry for my bad explanation. I meant B5 brighter that ASP in general. However, the distribution of the medium-light tones is stronger in ASP. Conversely, the high end of the high-lights has more details in ASP than B5 (=> easier to recover the h-lgts with ASP than with B5). By saying such, let's be aware that I do not come down to a strict conclusion, since B5 has several look profiles that we were used to play with. And they make a noticeable difference.

Cheers.
