resizing question

[lucid image]

A very simple question that I am sure will beg a very simple

answer. If one of my wedding clients wanted a low-res disc of

images, do I simply interpolate them down to around 500ppi on the

short end, save them as a jpg and that is it. Will this prevent them

from upsizing again without losing quality, or am I going about it

the wrong way?

 

Thanks

Yeah, that's pretty much it. You probably want to do a slight sharpening to give the image a good appearance after a significant downsize. For web-size/on-screen display, you could probably go to 500-600 pixels on the long side, actually.

 

Some people claim they can print at 180ppi and get ok results, which would make a 600 pixel image a little over 3 inches. You could make a 4x6 that would satisfy some people without high standards, but that's about the risk level.

I have an action, where I run all images down to 600x600 (that is, it's never greater than 600 -- 600x400 or 400x600), run a smart-sharpen at I think 80%/.8/gausian, then throw on a visible watermark. They've already been renamed, so there's no need for that step. Saved as JPG level 7.

 

The PPI does not matter, but I always adjust it to 72 DPI anyway, mostly for S&Gs. 600 px is 600 px.

You should download "Dr Brown's Image Processor" action. Works GREAT and there is a

tutorial online (all free).
