Scaling way down

[rogertb]

Hi chaps - newbie here ... I am working on a button for my web site and have a pretty simple round button with some highlight etc. I've been working at 300ppi with an image size of 400px square (in Pshop) but when I scale down to 72ppi and 30px square the quality is pretty poor. When I import it into my site it seems to have a few extra pixels at the bottom (ie the anti aliasing has compromised somewhere) so it doesn't look like a circle any more. Any advice please - maybe pref settings (currently bicubic) or any other advice greatly received. Many thanks Roger

if your button has text on it , which im guessing it does, if the layers are merged the text will become pixelated because you have to actually reduce the text size and not reduce it when its merged with the other layers

hi,
something to think about......
dpi itself you basically changing the distance between pixals!!
if you leave the resample box checked....... and change the dpi... you'll be adding or subtracting pixals.. because it will try to maintain the doument size..!! .... note: you'll also see the files size changes because it adding or subtracing pixals....

now if all you want to do is just change the dpi and not the pixal deminsions... then uncheck the resample box ......!! see if that works for you.....

He's already said he wants to scale down to 30px and 72ppi - I think that rules out this option.

Rogertb, when you're making images for the web it's best to create them at the actual size you want, instead of creating them way too big and then resizing. For the best results I'd advise you to go back to the drawing board an create your button at 30px. If you can't do this then you'll have to touch up your resized button manually or look for a reducing plugin that will do a better job of it than Photoshop.

No text bambam but thanks for your response and to you jerryb - and rach I think you're probably right about working at the final size (can you imagine trying to draw the smiley things you used in your post at their published size) ? I'll look out for a plug-in - I thought photoshop did it pretty well, obviously not.

So again good of you all to help me out here. Roger
