Naturally, I started with Super Junior. I looked for the sharpest photos of them that I had taken during their concerts and tried to clean them up a bit and generally make the photos look nicer. They aren't perfect, but at any rate I think they look better than the original. Here are the before and afters for comparison.

This is Siwon. I cleaned up the background and followed the tips in the article to get the retro look with curves. The next photo also uses this method, but I think the effect is less obvious.

Yesung, singing. I edited out the extra guys in the background (Kyuhyun and Leeteuk, I think?) and cleaned up the noise. Actually, I cleaned up the noise in all the photos.

The noise was especially bad in this one, because I was using an older camera (this was taken during Super Show 2, unlike the rest which were taken during SS3) but I was proud of myself for managing to take this relatively sharp picture. If you full view it you can see that the edited one is blur in some parts to get rid of the noise, but the edges are relatively intact -- another useful trick I learnt from the article. By the way, this is Eunhyuk, in his Chu~ outfit.

And here's my favourite. It's Sungmin, suspended by balloons (but actually wires) and throwing confetti into the air. It was quite a pain to edit out the background but I'm quite happy with the result. I might be thinking of incorporating this photo into my coursework because of the balloons (which in my mind somehow relates to the cliche 'flying colours') but in case it doesn't really, I think the time spent on this was still worth it.
That's it for now!
P.S. To those Suju fangirls who read this (I know you're there), if for some reason you want a higher resolution of the pictures, just leave me a comment! :D
