Upsize (Contrain Proportions)

[R Hardman]

I have checked the threads on upsizing and I'm left with one question. I'm using PS5.0 and will be upsizing in 5% increments. Do I add 5% to each width and height with Contrain Proportions OFF -OR- Adding 5% to the width and checking "Contrain Proportions" ON, be better? The final dimesions are different on the height between the two so I assume there is some distortion. Any help would be great. Thanks.

Yes, constrain proportions. You want the same aspect ratio when you're done. I'd also do 10% increments, which has been excellent from my tests - though I've never tried 5% so this is a guess.

I saw your info here: http://photography-on-the.net/forum/showthread.php?t=37151 and it works quite well. I also read somewhere that someone got positive results in 1% steps. It's pretty easy to create an action that does it so I'll give it a go. My computing power is good so it should take only a few minutes to run through. Thanks for the tips!
