I am processing this morning shoot and playing around with different canned prifiles in C1. I did WB these thn tried the leica M8 profile that is in C1 . Than i tried the Epson RD1-s profile . Look at the difference. Oh and these are with the IR cut filter 50 lux here

 

1 M8 profile

2 RD1s Profile

Now Jamies is not working because it is not profiled for the IR cut filter , so we can eliminate that but the M8 with the IR filter has a overall yellow /cyan cast , But the RD1s and the Leica R9 profile bring back the blue sky very well and the skin tones are getting a little more neutral.

 

I think folks should try this on a couple images and see what you think. Now I have said all along and Sean has too we need a new profile with the IR filters but in the mean time this maybe not to bad to try out and see. The never ending battle for color management and you guys thought digital was easy stuff:D

Reality is they have purple on . The blue sky is better in the RD1s and R9, Now I just think maybe a touch to yellow in the M8 , that is the one that is bugging me to tame down some

Now went back to the M8 profile and pulled the saturation slider down -20 and it looks pretty good. Off to bed and will try some more of this tomorrow but maybe some folks can play around a little and see if this is working

Yes the do , I think the RD1s maybe the one and add just a touch of saturation. I added 10 point here on the RD1s

Interesting comparison here, Guy. Another good example of the complex "art" of profile making. Kind of like taking the same scene with several different film types.

 

On my screen here, I think I prefer the skin tones in the slightly desaturated M8 profile on this image, but I'd sure like to see more. In a portrait like this I can see room for several artistic interpretations. I myself am a bit (too much of) a tweaker in C1, depending on the image series. Even with the DMR profile, which is pretty good, I will play around slightly with the color.

 

By the way, did your clients know about the M8's IR issue when they picked out all those shades of magenta and purple to wear, just to mess with you??? :)

Yes I told them to wear magenta

 

Here is one from Raw Developer.Need to play with this program, which has some great controls

RAW developer is an excellent converter.This picture look very promising: did you use some specific profile or just the standard one?

 

Did you try to convert a non-filtered leica image that had some magenta cast on it?

 

Another interesting software is lightzone 2. I use it all the time. Since I don t have a M8 and cannot check them with that camera. You can get a fully operational Demo of Lightzone 2 which accepts DNG file and I guess Leica M8. Enjoy and keep us posted.

This one was out of raw dev M8 profile , I did lower the saturation just a little but that was it. I may run out and shoot some shots of a little cowboy town after another family pic. Not a big fan of this type of work but there friends so what are you going to do. More testing subject:D :D :D

Guy:

 

Were the baby's velvet top and the grand-ma's jacket both maroon or were they black? How about the squares on the grand-dad's sweater -- looks like they might have been a combo of maroon and black or dark gray.

 

Without knowing the answer, it looks to me like if those were all maroon, the R9 profile seems decent with a saturation tweak.

 

If those were all blacks then Jamie's is the only one even close, but needs added saturation, a touch of yellow and maybe a little less cyan.

 

Tough call without being at your monitor with you...

Yea I know they all wore purple outfits so the colors are pretty accurate on that with the M8 profile and even the R9 so yes there really is not any IR stuff going on since I had the filter on. More looking at sky and skin tones here but I may find a shot that is easier to see what may work. I just shot a family in white so that would be better to judge

Customers , all I told them was to avoid white. LOL

 

Seriously I hate to see if i shot this without the filter , God knows what would have happened . Were talking real purple color here , like a NBA purple

IMO only, but ignoring the clothing and looking at sky, skin and the greens and yellows in the cacti, none of them are very good on all counts. Raw developer conversion is probably the best compromise, but skin is too yellow and sky is too cyan.

 

I'm 100% with you Jack. The RAW Developer conversion is the best, but sky & skin are off. Yellow & Cyan in the sky, and yellow in the flesh tones....
