Am working my way through the Richard Harrington tutorials and find them really helpful. There's one where he's working with adjusting the levels of a picture. I can find the levels adjustment, but I can't for love nor money find the 'adjustments' or 'masks' tab. Where do I find these?!
I've got the 'layers, channels, paths' box - and the 'colour, swatches, styles' box. But not the 'masks, adjustments' box. I can't seem to find any option which allows you to view these either.
