Adobe has provided a public beta of the upcoming online image-editing platform “Photoshop Express”. It can be tested for free on the official website:
Photoshop Express offers standard image-editing operations like transform, rotate, sharpen, white balance and effects like hue, tint, sketch and even a distort-effect. The operations can be applied through presets or a slider which goes very nice. The whole system works well and is a nice tool for quick-editing images on the fly.
