I used the photoshop express program available on the IOS system to modify a photo I took exactly one year ago. The photo was already of a weird quality due to it being taken with a 3DS, so modifying the photo proved to be a rather odd exercise. I changed the detail by sharpening it to the highest level. I then oversaturated it with red and blue to make the purple strong but to not make it look quite so solid. The fact that it was such a simple photo made it a very good choice, little to no difficulties with maintaining lighting stability or anything.
p.s. I was trying to go for a miami 80s art direction.
