Camera Profiling with ColorEyes

Camera Profiling with ColorEyes,

I'm thinking of using this software to make a few profiles for the M8 but, before I buy and try the software has anyone tried it and if so what results were gained?

Did it work with outdoor lighting in the 4500-6500K range and what about the studio 5500k strobe lighting?

Also, would you say you had the same amount of color correction work in processioning for the final print except that the Magenta Cast had been pre removed but that some color casts were still present....or were the images pretty much color cast free?

Cheers
Barry

Personally, I don't think CameraEyes is up to profiling the M8. I've used it and it's just not neutral or sophisticated enough.

The target is extremely glossy, and hard to shoot. They insist you use one light, but even in a typical soft-box copy stand arrangement it's a trick.

I find the photoshop plugin also hard to work with, and the resulting profile is nowhere near where it should be; it's posterized and magenta-shifted.

So I'd save your money on that one, if I were you!

Thanks for the 411 I was always told that camera profiling was tricked up but I though after reading there HYPE that maybe it would really relieve the magenta shift and that would be one less thing to have to correct.

They maintain on their web site that one light source is the way to shoot the target as it is not influenced by other sources. Also that the target source is best shot with out refelection. then they end their on line instructions and leave you hangging. this is when I started to doubt the credibility of the software because they dont tell you the whole story.

Barry,

I have been shooting targets for camera profiling since about 1998, in pretty much all cases its safe to say that this is NOT a exact science. all of these targets have some shortcommings, I personally find making a RGB curve correction from a Kodak step wedge or the Gretag macbeth grey targets is about as reliable. requires no software only a bit of experience from the user.

Keep in mind that profiles practically changes every time anything in your shooting enviroment changes and in turn affects the color balance of the light in this enviroment, this is little things like one strobe being warmer than another one and so on.. But its easy to create a saved photoshop curve which is a "general" fit for your studio or say tungsten stage lighting. then just batch.. I generally run a action which stops and wait for me to press OK for each image giving me the option to make a general density addjustment on the fly if I want to.
