Below you can see a pretty self-explanatory chart. Everything was done in Photoshop based on a still frame taken from the video. Things are divided as follows:
- GoPro 3 Black vs GoPro 3+ Black
- 100% versus 200% zoom
- "Raw"/cineform out-of-the-camera vs color graded (sharpen and curves)
If it is difficult to figure out which side is the 3 and which side is the 3+, congratulations - you just came to the same conclusion I did.
If you do look closer, there are some very subtle differences that most people (myself included) won't notice or care about. The GoPro 3+ IS a little less sharp than the GoPro 3. Personally, I don't think it is too noticeable even when you zoom in to 200%. White balance seems a little more accurate and less muddy with the GoPro 3+. Also seems like the exposure is up just a tad on the GoPro 3+. Not sure if this is necessarily a good thing if it is across the board because you might get some blown highlights.
