Thanks Chris & Sarah. That's very good news, saves a bit of re sizing time 

Yes good news on the quality front if you want to sell. Presumably the POE mechanisn for shrinking the images for web use will still care of themselves and create small files to view keeping the large file for sale purposes. The larger the iimage file theoretically the better the image quality, although that does work converesly as well, a large file of a poor image will just show up the imperfections more. So make sure your sensors are clean and there is no dust on the lens. Also use a lens hood wherever possible .. they do make a difference ...that is why lens manufacturers make them!!

Not at all Martin, a good 'small' image will sell over a 'mediocre' large image 9 times out of ten. I asked a similar question of Chris and Sarah over the weekend and they told that previously many images around the 2-3mb sold very well. As I indicted above theoretically a large image should mean better quality,  but not always. But at the end of the day if you have what the buyer is looking for you are in with a good chance.Big isnt always better, I feel it would depend on what use the buyer is looking to put the image. If they are looking to make a small brochure of some sort then the smaller image is ideal, if they simply like a picture and want to frame it for hanging on their wall then a larger one would be preferential.

Oh .. ok .. thanks for that info Dave .. much appreciated
