With all the pictures I take, the camera photo count rolls over. Sure would be nice if Canon expanded the file count. would also benefit people wanting to know how my shutter releases have taken place??
Since getting the 5diii, I've been able to "customize" names (ie/ pictures from India became IND_xxxx) but this still has some limitations. A file name that routinely embeds the time and date would be nicer so I could just get that info from the title without opening up the file for more EXIF details.
Using a batch renamer app after copying the files off the card opens up many possibilities. I organize files in Aperture by date, and and with geotagging and face detection I can easily find images I want.
