Grocery market http://www.pbase.com/miljenko/image/37400285 shot with very sharp Sigma 15 mm fisheye and saved as RAW. Read with 6 different RAW converters: Nikon Capture Editor v4.1.3, Adobe Photoshop CS with Adobe Camera Raw v2.3, Phase One C1 LE v3.5.2, Bibble Labs Bibble Lite v4.1, Raw Magick Lite v0.935 Beta and DxO Optics Pro. All set to default values, with sharpness (where adjustable) set to min. Pics imported into Photoshop CS as 16-bit tiff or psd, white balance and dinamic response tailored using the same grey point reference spot, cropped and sharpened with plain sharpen filter.
Findings: NCE and Raw Magick have the most accurate colours (I've being there, so I know!), C1 and Raw Magick are the sharpest. Other conclusions are up to you....
Let me hear your thoughts!
