I'm just starting out with stacking in DSS and am a bit unsure about what is really happening with regard to file size. My .CR2 files are around 19Mb and 4752 x 3163 pixels. Considering the stack of ~8 images is still roughly the same pixel size, I would have thought that it is simply storing new pixel values representing the stacked values, hence the file should not be significantly larger, but the saved .tif file out of DSS is ~90Mb. It seems like the cell values aren't really merging, but being retained as a stack of separate values, hence multiplying the file size? (I realise .CR2 and .tif are different formats but I doubt they should differ by that much). Formats aside, I'm left with a 90Mb .tif which turns to absolute garbage trying to get it down to 200kb to post here. I've tried the "save to web" option that others have suggested but the quality is very poor. The closest I've got to 200kb is if I do a "print screen" and then resize the screen grab. What am I doing wrong? So many of you post images that contain such detail; even at 200kb, so I'm keen to learn how it is done.

Comments welcome,
