![]() ![]() Here's where things get interesting: now we specify a gamma transformation corresponding to the sRGB (-g 2.4 12.9). Using the sRGB color space does NOT by itself apply a gamma transformation, and the -4 option implies -g 1 1 (so we stay in linear space) camera-specific), with 16 bits/channel (-6), fixed white level (-W) and no gamma transformation (-g 1 1)Īlmost the same, except that the image will be in the sRGB colour space (-o 1). Image will be in raw colour space (-o 0, i.e. This equivalent to dcraw.exe -v -w -H 0 -o 0 -q 3 -6 -W -g 1 1 -T T : write converted image as TIFF with metadata I'll just list the conversions you used in the order they appear above, then say where I think something might have gone differently than you expect (or perhaps not)įor those not familiar with dcraw, I'll explain all the options used: Here are my dcraw settings: NOTE: All saved out as sRGB JPEGs in Nukeĭcraw.exe -v -w -H 0 -o 1 -q 3 -g 2.4 12.9 -6 -TĬan anyone suggest whether I'm going wrong somewhere? The files are pretty big, should I convert to Jpeg and upload?Īre you sure your conversions do exactly what you think they are doing? The thing I'm not sure about is with regards to my sRGB conversion(s), I would expect to be able to linearize these and they match my linear images but they don't, they are much brighter - and I say 'they' because I've tried a couple of different options. Although I'm wondering if it's more complex than I first imagined? There's a clear difference in vibrancy but I'm pretty happy that is because of using sRGB primaries and the other not. I'm using Nuke as it works in linear space but displays all inputs in sRGB space, you just tell each input node what colour space the incoming image is.Īnyway I'm trying to verify that I'm able to acquire images with the following conversions:Īnd I want to open in Nuke to compare, linearize/gamma/convert to ensure I have used the corerect settings and understand what I'm working with.Ĭonversions 1) and 2) look (in non technical terms) the same in terms of exposure/contrast (viewed in sRGB gamma space). I have been experimenting with different dcraw conversions and am comparing the results in Nuke. Wondering if someone can shed some light on what dcraw is doing to my CR2 files. RawDigger can keep RAW data safe without conversion and display the RAW histogram in different modes.I've been browsing these forums for a while. You can browse the RAW images and videos with it. For instance, you can view the RAW histogram of the entire image or the selected portion. What else can you get from RawDigger software? You can get the answer from this section. RawDigger is a RAW image analyzer that can display and research the RAW histogram. You can export the RAW histogram as CSV or PNG format for further study. Here is the complete RawDigger review you can check. Investigate camera settings and behavior, including ISO settings, dynamic range, accuracy, repeatability, uniformity, etc.ģ.ĭetermine the RAW level, exposure, and histogram.Ģ. Get a look at RAW data to compare with RawDigger.ĥ. Create device data for color profiling.Ħ. Get an in-depth analysis of the camera or sensor.ħ. Support a wide range of image formats, cameras, and extensions.Ĩ. Access RawDigger exposure, research, or profile edition to study RAW data at different levels. No precise RAW histogram with controls on the small display window. You need to open RawDiggger from FastRawViewer.Ģ. The RGB rendering in RawDiggger is for reference only.ģ.

So beginners may have difficulties while analyzing RAW data with RawDiggger. ![]() RawDiggger offers a 30-day free trial for every new RawDiggger user.
