The magic wand tool really is magic, when you know how to use it. You shoot a model against a white background so you can cut them out but the quick selection is struggling even with its refine edge, try the magic wand tool to select the white background and then inverse the image. Tutorial here .
Just watched a video testing the Nikon D800 as it is claimed to have the best 36m sensor on the market so to really push it they tested it with a Hasselblad H4D 40 40m pixel camera. To be fair the Nikon is about £2,500 and the Hasselblad £16,000.
The result in a pro studio the Hasselblad is clearly better, closer to real colours, more tones, sharpness you name it the Hasselblad won it, but not by huge margins. Out of the studio it was closer with the Nikon winning anything with higher ISO.
The Nikon is sure to be a huge sucess.
Welcome to my blog. My photography is on a tight budget like so many others out there, but through this blog I hope to show that great photographs can be achieved by all.
