Hmm tricky...I wouldn't take my chances on this technique. With portraits I would never use it and if your composition has a higher dynamic range it wouldn't always mean the more signal the better (for instance silhouette shots or landscapes, perhaps you select a photo wityh a lot of detail in the foreground while actually you want detail in the background etc etc). Furthermore if settings are the same, it could be done, but I like more safety when sorting my photos. To be honest it doesn't take to much time downloading them all to a pc and loading them into Lightroom or whatever program you use and deleting the bad ones.


And if settings aren't the same same, forget about this technique. Higher ISO also means bigger files and a higher ISO isn't always preferable.


Anyway I like taking a little more time (only a little) and be safe and in control, but if it works for you be my guest [H]
