Didn't we just went through this already for using raw files to measure flash speed and not jpegs?

IMO zipping wouldn't make a difference, since one has to unzip them first back to the original format before the program (ie NikonView or a Photoshop plug-in) can decode them... Some pro dSLRs do compress their raw file , but at the expense of a longer extra step for a smaller file size... either way the original raw data monochrome reading from the CCD has to be decompressed again or preserved to complete the interpolation to a full color pixel. For example adjacent pixels are usually not in-line when data is shifted out from the CCD, but are on the N-1, and the N+1 line, and the consecutive pixels are usually of a different color R, G, or B making any compression not very effective...
