High Dynamic Range (HDR)

Just a quick reminder to all the imagers who struggle with the low dynamic range of the video cameras we typically use for planetary images: Adobe Photoshop CS2 and CS3 have an HDR function which allows the merging of multiple images of varying exposures in order to get a single image that captures detail at both ends of the EV range. I have just begun experimenting with this and you can visit my website for a brief tutorial and example.

There are also HDR software packages available that work independantly of Photoshop. One of these is called Photomatix. It has more user controllable features for fine tuning the final image.

Cheers,
