Your web browser uses another rendering engine than Photoshop. This might be why you see differences. Can you show us what's happening in PS?

It’s Lucida Grande.
This is how it renders on mine (Mac):

The extra weight in Jan's image is due to a rendering bug in Firefox (?) when rendering light text on a dark background.

Yep, that was Firefox. But it doesn’t look that much different in Safari:

But you can fix that with some CSS, but we are veering off topic :)

Hi guys this is what I had in photoshop (the bottom one) without any antialiasing.

But I think I have worked it out, as soon as I tried this with (sharp) antialiasing, its pretty much identical to what I see in the webpage, so as Frode Frank says I guess what this is telling me is that there is some slight rending going on in my browser, and that it's not just a pixel font.

I guess I've got to research some more about webpage font rendering/@fontface clear type, that sort of thing.

Set the type in the browser. Screen shot. Paste into PhotoShop.

also guys talking about Lucida Grande, what version of the font is this?

It's slightly different to the Lucida Grande I have, and I have tried back to backing Lucida Sans Unicode and plain Lucida Sans.

Whatever this version is it seems a little bit more open and smoother, simpler in its forms. The M has a wider base, e and a's are more rounded and open.

Any help would be great

don't worry worked it out, it was Myriad I was after.
