See how one of the best photo retouch studios works in Photoshop.

Photographic retouching studios that work in fashion and editorial are usually cagey about the work they get up to. While car and beer brands are usually happy for studios to show the craftsmanship that goes into compositing elements together for a billboard or magazine spread, the fashion industry likes to pretend that those shots you see were created in-camera – not Photoshop.

So it's great to see these four videos from New York-based Rare, whose clients include luxury lifestyle magazines and brands from Vogue and Harper's Bazaar to Tiffany and Tom Ford.

Of course, the work these time-lapse videos feature by Rare's founder Elizabeth Moss aren't likely to be from big brand campaigns – but the work on show is impressively crafted. The video above shows the most in-depth work – six hours of retouching condensed to 90 seconds – with the videos below showing 90 minutes and four hours work, plus a montage of different projects.
