Changing image size

[treeman]

Ok So I was asked to provide an A6 advert. So I started with a new PS file sized to A6 then added layers of text and images. Now I'm told they want it A4 too, so I just change the document size to A4, and was expecting the quality to be awful, but it wasn't, no discernible difference :shrug:

Surely it should be rubbish, I've even done an A4 print to check and it looks fine :shrug:

I'm not complaining as it's made by life a lot easier, just curious how that is?

If you did the A6 file at 300dpi
When you increase the file size to A4 it will have probably changed the dpi to around 70-80 ish. Still useable but I would recommend doing it at 300dpi especially if it's being printed

That's what I thought, but the A6 was at 240 dpi and so is the A4 :shrug:

Newer versions of photoshop are VERY good at scaling up images, and text you added (as long as it was still a text layer) I believe will resize fine as it just increases the font size.

It was the original Tiff file with text layers that I upsized, and I'm using CS5 so maybe that's it, awesome!!
