My Canon is only 12 megapixels, but i've learned that good lighting is almost as important as the camera itself. I take my pictures right next to a window, against a white wall and on a white piece of cardboard.
Regarding the United line, I only have Jazz and Megatron because they looked so much better than the regular releases.
Most of the time I prefer the U.S. figures because I'm not a big fan of metallized paint apps (I don't mind if the plastic is actually cast with a bit of glitter in it but Takara tends to overdo it).
At the moment I'm on the fence about getting the HA wreckers... They don't look bad on their own but it seems that they aren't as good as say Barricade or Jazz from the previous line.
The Ark playset I'm definitely going to get, and I'm really looking forward to the Movie Masterpieces of Sentinel Prime and Ironhide. If Takara comes up with something as good as Starscream and Buster Prime, those guys are gonna kick some serious a$$ !
Classics-wise, I'm pretty sure I'm gonna get the G1 SDCC re-issues of Soundwave and Blaster. Gotta love the boxy look !
I've also checked out your collection topic, you've got a ton of stuff! Amazing. That reminds me I need to get the Starscream Masterpiece as well. If only I had more $$$ to buy 'em all!
