How curious! It's as if it's camera takes long exposure photos with an ND filter; it looks very much so from the waterfall photo and from the fact that you have to stay still.
I didn't know the GB Camera could be used in the Transfer Pak to put photos into Mario Artist! I know one of them had a 'capture card' that could be used to screenshot videos and use them in-game, but I didn't know about the GB Camera compatibility. That's really cool.
The background blur on the acorn photo looks amazing! My FD75 is not that good in this aspect, probably because it doesn't have enough image resolution. But I love how all Mavicas do depth of field.
