By default, it just rips the embedded JPEG out of the RAW file. You can set an option for it to use Canon's conversion .dll, which has no options, and probably converts like FVU with the default options. I tried it once and it was *extremely* slow. I use Irfanview to cull my RAW images, but by reading the embedded JPEGs.

There is a functional free mode. http://digitcamera.tripod.com/#slr Adobe Camera RAW & DNG Converter (both v3.3) > Adobe Camera RAW & DNG Converter (both v3.3) Free indeed, but not standalone - they need a paid-for product to work with. >> Adobe Camera RAW & DNG Converter (both v3.3) >> > Free indeed, but not standalone - they need a paid-for product to work > with. Yes and no. You can convert to *.DNG then rename to *.TIF if you're desperate. >Pixmantec RawShooter essentials >IchiKawa SilkyPix >Canon Digital Photo Professional >Is there anything else, excluding timed trials? >http://digitcamera.tripod.com/#slr There is IRIS (http://www.astrosurf.com/buil), which doesn't really give normal conversion; it just (optionally) interpolates the RAW data in three separate color channels, and doesn't use any color profiling or true RGB conversion but it can be useful for examining RAW data, as it displays the actual values under the cursor. You can also make very good B&W images with it, by not converting to color, and "binning" the RAW data at 2x2 pixels. What you wind up with is a 50% resized B&W image with excellent contrast, at 14 bits. You can also output the three-color image and use a channel-mixer in greyscale mode in an image-processing program for better B&W. Regular color conversion really ruins images somewhat for use as B&W. The difference is like real B&W film vs B&Ws made from color negatives. There is also DCRAW, a command-line converter with many output options. Its free source code is the foundation of many other RAW converters, or was so in their earlier incarnations.

Interesting tool. > There is also DCRAW, a command-line converter with many output options. > Its free source code is the foundation of many other RAW converters, or > was so in their earlier incarnations. This can be useful. It gives a sharper conversion but with more jaggies, less anti-aliasing filter and a very high gamut output, and a few extra pizels around the edge!

It gives a sharper conversion but with more > jaggies, That was the case with the VNG (Variable Number of Gradients) interpolation method when high contrast edges/lines were involved, but is solved since August 2005 by the more recent (default) AHD (Adaptive Homogeneity-directed Demosaicing) algorithm: <http://www.accidentalmark.com/research/papers/Hirakawa05MNdemosaicTIP.pdf> <http://www.accidentalmark.com/research/papers/Hirakawa03MNdemosaicICIP.pdf> <http://www.accidentalmark.com/research/papers/Gunturk05Demosaic.pdf> Bart > SNIP > [quoted text clipped - 11 lines] > <http://www.accidentalmark.com/research/papers/Hirakawa03MNdemosaicICIP.pdf> > <http://www.accidentalmark.com/research/papers/Gunturk05Demosaic.pdf> Hmm, I found the new version but it's converting to a different RGB profile now?? http://www.insflug.org/raw/ these are the parameters I used with the feb 2005 version: dcraw -v -b 4 -3 -w myfile.nef SNIP > Hmm, I found the new version but it's converting to a different RGB > profile now?? http://www.insflug.org/raw/ The new version 8.03 apparently traded the -m parameter for an -o parameter (Output colorspace), which allows to select between Raw, sRGB, Adobe RGB, Wide or XYZ encoded data. > these are the parameters I used with the feb 2005 version: > dcraw -v -b 4 -3 -w myfile.nef Try adding an -o 1 or an -o 2 parameter for sRGB or Adobe RGB, depending on what your workflow uses. Bart Thanks, wide gamut d65 color space is what I wanted. -o 3 One thing I use it for is reclaiming blown highlights, I stumbled across this version that produces linear conversion useful for that: DCRaw -n -b 0.25 -m -3 -o 3 myfile.nef > SNIP > [quoted text clipped - 12 lines] > > Bart SignaturePaul Furman http://www.edgehill.net/1 Bay Natives http://www.baynatives.com > Thanks, wide gamut d65 color space is what I wanted. -o 3 > One thing I use it for is reclaiming blown highlights, I stumbled > across this version that produces linear conversion useful for that: > > DCRaw -n -b 0.25 -m -3 -o 3 myfile.nef Looks like it should do that with a -b 0.25 an an -n, however I doubt if the -m parameter still does anything (the -m option is no longer mentioned on the list). A small word of caution with respect to too wide a gamut. Upon conversion to a much smaller gamut, posterization can occur.
