Last call for color-target shots for inclusion in RawTherapee 5


(Morgan Hardwood) #41

@Jonas_Wagner I hope you are recovering well from your balcony injury. On closer examination the photo has quite strong motion blur which sometimes makes argyll-scanin fail miserably, and other times it works. When it works the DE values are fine. I will add it as we have nothing better, but I hope you can send in a set of D810 D65+StdA shots without motion blur, as per http://rawpedia.rawtherapee.com/How_to_create_DCP_color_profiles#Shooting_the_color_target

@ilias_giarimis I did as you asked:

  1. Which DCP should I use for RT5 released later today?
  2. Should I set D810’s white level to 15700 in camconst.json for RT5?

(Morgan Hardwood) #42

You’re quoting point 1, while it’s point 2 which is for LENR. “Built-in noise reduction” = LENR.

Thank you for the shots. Looking forward to a tungsten cc24 shot.

@ilias_giarimis will you process those D800 photos or should I?


(Ilias Giarimis) #43

Sorry for being so late … I can start now with d810.dcp evaluations and camconst.json updates (D810, D800) … but it will take some hours … when is the dead line for RT5.0 ?

The case with Nikon unequal WL is an old one where a user and sample contributor (RusselCottlell) mentioned that it was not working well … since then RT’s highlight handling changed and no further evaluation took place :frowning: so I am not sure about this but I think that equal WLs (same as the converted to DNG NEFs) should work better for profiling.
Are the logs of building these Dcps available ?.

@ilias_giarimis we just released RawTherapee 5.0. I used the 15700 DCP and left the WL in camconst.json as it was before - that was my best interpretation of what you meant. I tested it on a few shots and saw no problems. We can always improve things for 5.1.

I will not be able to perform tungsten lit shots of my X-Rite Passport until at least the end of the week (not sure yet).

Short reason: somebody stole the parcel with the tungsten bulbs I had ordered :frowning:

Longer story: this morning before going to work, I checked my mailbox and saw that the parcel had been delivered, but as I was already a bit late, I decided to let it inside the mailbox (instead of securing it in my flat, two stories upstairs). When I came back at noon, the parcel was gone.

My facial expression when I opened my mailbox again at noon to find it empty, was certainly interesting :astonished:

I am quite sure the person who stole this parcel will be be disappointed.

I ordered again the bulbs. Waiting…

It will end up costing them more in electricity bills… :smile:

Got my tungsten bulbs! Not stolen this time ! :joy:

I’ll take the shots this week-end.

Is it interesting to also provide X-Rite Passport (both sun and tungsten bulb) shots for the Sony Rx100 (first model)?


(Morgan Hardwood) #49

We’ll take all the cameras you got.


(Pata Kreyp) #50

Here are three RAW shots of X-Rite Passport (link):

  • Nikon D800 under tungsten lighting (_DSC8149.NEF)
  • Sony RX100 (model 1) under sun lighting (_DSC0503.ARW)
  • Sony RX100 (model 1) under tungsten lighting (_DSC0502.ARW)

I did not succeed making a dual illuminant profile, the Colorchecker application kept telling that the tungsten DNG file was not a proper one (although I made a profile with it alone…).

Hope it works for you :slight_smile:

@Pata_Kreyp could you re-upload the D800 tungsten shot, and the other shots?
