I have been using DPP's Quick Check - Full screen for years. RawTherapee can be invoked from the command line with the image file and processing script, so the same `xarg' approach can leverage your cores. Even inefficient `dcraw' can go fast if you light enough cores under it: ls *.nef | xargs -n 1 -P 32 dcrawįor the above, my 16C/32HT Linux box can convert seven 24MP NEF files per second. Multi-core and SSE boost the processing speed. Key features include 32-bit floating point values per channel and associated curves tool. I've watched this utility for some time and it finally looks mature. The underlying decoder is Dave Coffin's `dcraw', but interpolation and image processing is built on top. RawTherapee is probably the top contender for performace and, being GPL, is available at no cost with source. However, it is not good for viewing heaps of thumbnails at one time. It's histograms are for the raw data and show the data values of the pixels to give you a better idea of wiggle-room for adjustments. Raw Digger is worth a look too, especially for analysing the raw data. I can't imagine any significant reason for Lr and others not importing several images at once, instead of one after the other, but it doesn't happen. The only way to speed things up appreciably is to make intelligent use of multi-threaded programming, and people who do that will not want to give it away freely while the big-boys who charge money can't match it. Get used to the fact that raw processing takes time and you cannot eliminate spending that time if you want to see what you really captured, and even more time if you want to apply adjustments needed to present the huge dynamic range that can be captured by some of the modern cameras. You have to press A to look at the actual pixels, or else it will show you the built-in thumbnails (which will have in-camera adjustments that you may not want). CTRL-1 displays 1:1 (100%).įastStone Image Viewer is great but it does not convert raw files routinely. That display is really the only way to cull files that have optimum exposure but is not good enough to cull files for critical sharpness or noise, You can hit the J key and FRV will quickly display the embedded jpeg file which can be used for sharpness culling. I looked at the FastStone web site and it seems to use the jpeg file to present the histogram too.įRV is very fast, shows a low res raw conversion with a true raw histogram. Why this error is not corrected by camera manufacturers, Adobe LR, Adobe PS, Capture One, etc, etc, is a mystery to me. All other histograms are, in my opinion, wrong. If you want to cull images based on whether the raw data does not have blown highlights, FRV is the only choice. In FastRawViewer, you *can* have it show you the jpg instead of the raw if you want.įastRawViewer (FRV) is the only viewer I know that shows you the histogram of the raw data, not the histogram of the rendered jpeg. You can give your images a rating and when imported in LR (or another RAW converter) you can pick them up. For Windows and Mac and onlyĪnd it's a real RAW viewer as well (no embedded jpg). Have used it for many years, but Windows only. Generally want to go through them fast, and be able to check sharpness. If there is a program that will align them horizontal or vertical, like on the camera lcd, allow me to double click to get 100%, and show the images large on the screen, that might be good. I like the ability to double click for 100%. DPP would be great, but afaik I have to either open the images one at a time, or view as thumbnails.
