The small discrepancy (106 K) between the color temperature from the standard exposure and dual iso image in AWB is then probably due to the actual dual iso capture itself. The standard deviation in Color temperature I see is only 4 K. I shot 8 standard images (no Dual ISO) in AWB. When having an image open to work on, it's blurry now. I also checked how repeatable the Color temperature was in AWB with this setup. A few hours ago I upgraded from 5.0 R something to 5.3 stable on Win 10 64-bit (Commit: ec0f793).

Maybe the main download page for cr2hdr should be updated with that version? White Balance "Standard exposure CR2" "DUAL ISO CR2" " 00:01 cr2hdr –wb=exif DNG" "Danne cr2hdr –wb=exif DNG"Ĭolor Temp set to 2600 2594 2594 2594 2594Ĭonclusion: Danne's cr2hdr works well for AWB. I read the color temperature after loading each picture in Rawtherapee using its Neutral preprocessing profile. In both cases I used the option -wb=exif. I converted the dual iso, either using the cr2hdr compiled on Dec 4th, or with Danne's cr2hdr. I took pictures of an indoor scene on a tripod with controlled constant lighting.įor each white balance I shot a standard CR2 and a Dual ISO 100-400 CR2. #The final resulting AsShotNeutral tag to be used in the DNG file
#Inject into the DNG accordingly, uncomment if matched with processed DNG #Fetch the first pair of multipliers from a CR2 with dcrawĬR2_0=$(dcraw -i -v "$(ls *.CR2 | head -1)" | awk '/Camera multipliers/ ') Is there a possibility to set up the camera to take automatically 2 images in a row: one standard image with current settings (base ISO) and one Dual ISO image? That would make the process more convenient.Ĭode: #Place a CR2 file in a folder and run the following script to end up with the AsShotNeutral dng white balance tag So far I need to manually change the settings in the menu between shots to achieve this. So I would like to always take 2 images of the same scene (one standard and one Dual ISO). I am not sure I can evaluate in the field whether I really need Dual ISO or not. Is this the expected behavior? Does this affect the processing by cr2hdr?ģ. The white balance in the Dual ISO CR2 is not the white balance that I have selected on the camera, whereas for a standard CR2 it is. In addition I have a few other questions with respect to Dual ISO:Ģ. During development of the dng: Different postprocessing in Rawtherapee (different demosaicing algorithm?) During the conversion with cr2hdr: Different settings of cr2hdr?Ĭ.
During the shot: Different settings of Dual ISO (maybe a smaller range of ISO like 100-400, or 100-800?)ī. What can be done to minimize these effects? Where is it the best to address them?Ī. I would upload the cr2 files but I am not sure how since they are so big.ġ. Left CR2 developed/ Right DualISO DNG developedĪs you can hopefully see, the Dual ISO shot shows some green and magenta vertical artefacts (see for example the balconies, the window frames, or the vertical pattern in the facade). Processing Profile Neutral, AMaZE Demosaicing, White Balance Daylight, Auto Levelsīelow is a screen cap of some details zoomed at 100% I developed the two pictures using Rawtherapee 5.3 with the following settings: I processed the Dual ISO CR2 with cr2hdr default settings (drag and drop on the exe) I shot 2 pictures of the same building, one with no Dual ISO (Standard ETTR iso 100), and one with Dual ISO 100/1600. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.I am trying the DUAL ISO module and I would like to understand what is the optimal way of processing the DNG created by cr2hdr. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.
