While waiting for the confirmation email, I read a bit further and already found a hint in the "LibRaw Project Goals and Objectives: Planned improvements" towards my question: How well is the support for my Fujifilm FinePix S200EXR implemented?
The answer seems to be: "not yet complete". Supporting RAF files produced by EXR cameras has a quirk: As the sensor layout has diagonally arranged (octagonal) pixels, the raw files in EXR mode contain two sub pictures with different interpretation, depending on the operation mode.
Hi! I have converted RAW to TIFF (uncompressed) file and then demosaiced. I assume after demosaicing the image I can call in camera RGB; from camera RGB to I have converted into XYZ and XYZ to CIELab(76). My goal actually to create an ICC profile of the camera which I can use over other images. But now i am lost, how to create the icc profile actually?
Hi, Is there any way to convert from raw to tiff so that it appears as shown in the raw preview.
I know you can extract the jpeg preview, which is pretty much what I am asking for as it is basically what is shown in windows viewer. But is there anyway to properly convert from raw to tiff that doesn't change the colours too much from the ones that appear in the raw preview. At the moment the converted tiff is vastly different to the preview. I think it may be to do with the colour correction or white balancing. Any advice would be great.
Hi, I'm trying to use LibRaw to process a DNG file, with the bare minimum of processing. I've got the image in RawDigger, and I'd like to reproduce it with LibRaw.
At the moment, the LibRaw colours are too dark, compared with RawDigger.
I can get them to match if, in RawDigger, I set the "Camera color profile" to "no profile" (compared with the built-in profile).
So, I'm thinking LibRaw is not using the built-in profile correctly.
I use the dcraw_make_mem_image method to get a full-sized image.
But colors differ from "thumb" image.
I used the parameters use_camera_wb, no_auto_bright, use_camera_matrix but the result is still not the same.
Are there any ways to get a full-sized image with the same colors as the thumb?
For example, If you upload a raw image in Lightroom, the desired result is displayed.
I'm fairly new to using this library. I'm using the API to convert raw in c++ and output it as a tiff. I'm using the dcraw_process() function to do this. The only thing is the tiff is the wrong resolution. I wonder if there is a setting or something that I am missing. The raw image is 3648x5472 but the tiff is 3670x5496. Raw image is .cr2 format and was taken on a 1dx mark II. Any help or advice would be appreciated.
There was a need to make a debayer to data array. It is received from the camera and is just two-dimensional array in memory. What function it is possible from libraw it is possible to use for this purpose? Judging by the description it works with files, received from different cameras. And, it is necessary for me just with an array. The used compiler Delphi-7.
How I could apply the interpolation only without all other enhancements like white balance, output_color, gamma Curve and so on. I could create my own implementation of those but really need to get consistent data from a camera which capture 100 consecutive images. I am hoping interpolation will output consistent values for each images. Or any suggestions?
Hi thanks at first for your work. I'd like to know more about details camera white balance. I noticed that there is a variable called cam_mul, which is a list containing 4 float numbers. How does this variable is used? Multiply each number in cam_mul with the corresponding channel? But in some raw files, I noticed the fourth number of cam_mul is zero. Is there something wrong?
