I have setup my camera to take snapshots but today I notice that there are one digit, that is different on the filename, what does it tell me?

I think you can figure it out yourself when you look at the overlay numbers on the image

Ash... I didn't realize that it was exact the same time... so that's why there are 0 and 1 on the end!?

Possibly Substream and Mainstream captures?

 

[JGr!]

Nope, both have same resolution.

Maybe you setup your camera to take 2 snapshots or you manually click snapshot twice very fast. And since you can't have a file with the same name, therefore it adds a 1 for the second picture?
