The removable dust/hot mirror protector on all Sigma dslr models is a great feature for IR shooters. I'm wondering if that feature will be possible with shorter flange on the upcoming ff model. -Gary

My pet peeve is pedestrians and licence plates. In a busy venue like this, it's difficult to get any clear shot of car, but sometimes it works, sometimes it doesn't.

The FS-converted DP1 and DP1x, that I once had, produced the best FS colors, and were just a lot of fun to use. Most of the SOOC jpeg's looked great, without any editing. Man-made blue or red ...

Blacks and contrast are a tricky thing in bw processing. For bw IR, I prefer darker, but not absolute black in the sky, while retaining the snow white qualities of the trees and foliage. For me ...

I gave color/AWB/Ntrl a try today, but I don't I don't see any appreciable difference between a color processed to bw or Monochrome mode. I also took some shots with the Monochrome mode 'Filtering ...

The one thing that I hadn't tried, was to adjust the sliders in the sdQ 'Monochrome' menu, as mentioned in the Tim Shoebridge article. As soon as I made the adjustments, the whites were brighter, ...

Thanks Laurence...I think I've figured it out to some degree... -Gary
