Baseline query when saving images

Post by Mountain Goat »

Could anyone explain the difference between saving as Baseline Standard or Baseline Optimised or Progressive when saving images (to be used as 50k files for AdWord Images)? I'm using Photoshop Elements.

Thanks.

Use Baseline optimised...

Progressive gives a "fading in " effect as it downloads in scans - which looks a bit ropey and is less efficient in terms of filesize.

Baseline standard is only necessary if you need your pics to be visible on very, very old browsers. It's pretty specialist these days. Optimised will give you much the best results.

Most important thing is to convert the colour profiles to sRGB to keep the colours bright...

Mmm, thanks Firebug.

I don't think Elements has anything to convert the colour profiles. I've wound up P'shop 7 - may I ask where it is?

If I pick out an image it appears to be 'titled' by default as:

image.jpg 33.3% RGB

Or if I look in Colour Settings I can change my RGB working space to sRGB IED and a load of figs. Is that it? Out of my depth here.

Yeah, Elements might not have it.

That's it though - if you're working primarily online, you should always use sRGB, which was developed for monitor display.

Any images that aren't already in this can be changed via Edit > Convert to profile. The 'Save to Web' function will do this for you, but you'll get better results by doing it within PS first.

It doesn't show in the title bar - you'll be able to see it in the bottom left hand corner of the document - there's a percentage, then some text and an arrow. Click the arrow, you'll see the word "Show >" click this arrow and select "Document profile" to see the profile displayed there. Or you can configure the Info palette to show it, too.

My head's buzzing, but thanks, Firebug, will give it a go.

heheh, it's not as bad as it sounds!

Once you've set it up, you shouldn't need to do it again. To set it up, go to colour settings (for me, these are in Edit at the bottom)

Make sure your working space for RGB is set to sRGB
Don't worry about the other working spaces

Colour Management Policy -
RGB - Convert to Working RGB
Don't worry about the others, again

Profile mismatches - check "ask when opening" if you want it to give you a choice, or just leave unchecked for it to convert every RGB file for you automatically.

And that's it - all your RGB images will be in sRGB from now on.
