On What is equivalence and why should I care? article (2062 comments in total)

Sorry but you guys botched a bunch of this. :sigh:

"Total light" is completely unimportant. Yes, there is less light hitting a smaller sensor, but it doesn't matter because its a smaller total area. Light PER SENSEL is the same.

And lenses don't matter at all. Given a frame-filling grey card (as an example) a 50mm f/4 and 100mm f/4 will give exactly the same 18% grey image on any sensor size. If lenses didn't work that way, you couldn't have external light meters.

Larger digital formats aren't less noisy because they are larger so they collect more light, its because they can have a lower sensel density. In the film days, it was because you didn't have to enlarge so much with a bigger negative.

smdh...and I'm only on page 2.

On Service lets you order prints of any Facebook photo post (115 comments in total)

Eleson: Weird discussion.
Who are you all accusing of breaking copyrights?
- The person on fb that orders a print of a picture that you have agreed to share to them?
- Or the print service company that offers the service to print a provided picture on an item?

Think before you share. Or just be happy that someone liked a picture you took anough to spend some cash on printing it.

No. I'm not happy that photos I upload, which are my copyrighted IP, are being exploited by some unauthorized service so they can compete with me and sell prints. I sell prints myself and a third party does NOT have my permission to do so.

If this company was selling coffee mugs with Disney characters on them, you better believe they would be sued into oblivion.

Seriously? This is idiotic. The images are nothing alike.

On The 15 Minute Makeover: Photoshop Beauty Retouching article (169 comments in total)
In reply to:

Dirk Jan: Thanks for the write up! Learned a new trick after using PS professionally for a year or ten, hehe. Then again, I don't do much skin retouching.
Only one thing didn't work for me in CS5; copying the red channel and pasting it as a new layer through the the channel list. I did it exactly how you described (clicking to activate red channel only, ctr+c, clicking RGB channel -> ctrl+v), yet it only wants to copy all channels at once it seems. Through the Image menu it worked fine though.

I'm 47 and would put my work up against most of those posting on this board. Photoshop is a tool, used right it can make you images sparkle. I use a similar technique and get great results.
