Lightroom’s great, but sometimes you just want a slimline app to quickly view folders of images. If you’re an Apple user then Lyn is a great option. It supports JPEG, TIFF, JPEG 2000, PNG, TGA, RAW, HDR, OpenEXR, PPM, WebP, animated GIF and has an integrated movie player for video. It also has basic photo editing tools, geotagging capabilities and enables you to share your images on Facebook, Flickr, Dropbox, SmugMug, 500px and Picasa.
