Files for testing color profiles

I managed to get these files shot today. Not comprehensive color targets but the different lighting with the same subject is useful for testing targets. All the images shown here where done with M8 generic in C1 PRO as that's the baseline for C1 ICC profiles. One thing positive about the generic profile is it gave good results with all the files despite wildly different lighting.

 

I shot 2 with 5200K light, one with soft, flat lighting the other with more contrasty lighting. The one shot at 3200K has the kind of extreme lighting you might find by candlelight, bars, and various dimly light available light venues.

 

I'll get the DNG's on sendit over the weekend for anyone who wants to use them and post the address here.

For white balance I entered 5200K in the M8 for the strobes. Broncolor strobes are balanced for 5300K but diffusers and light modifiers usually knock them down to 5100-5200K. The 3200K image was using just the modeling light from a fresnel spot with grid which is 3200K. Those settings got me within 100K of the actual (looking at the colorchecker and WhiBal for reference). To bad I sold my Broncolor FCM color meter on eBay. I could use it now.

Here's the link to the files. There are 2 versions of the soft/flat lighting and the high contrast lighting. The difference is about a 1/2 stop of exposure. The high contrast image is just about at the limit of the sensors range. 1/2 stop one way and it was clipping highlights 1/2 the other and the shadows were clipped.
