you can contact the author directly - the software is not bug free

Thank you, I sent an email on 2/27 and one earlier today and am awaiting a response.

I have a question I am wondering if anyone can answer.  I have a film scan of a Color Checker SG that I measure the patches of in 3DLUT Creator and then use that data with a Babel Color Patch Tool reference file to create a DNG Profile of in Lumariver Profile Designer.  When I render the profile, the patched definitely change to close to the reference patches...especially the hue, but almost all of them are quite a bit more saturated and either lighter or darker than the reference patches.  I have everything in the Profile Designer set to default and have tried utilizing almost all of the tools and options available, but that only makes things less accurate/pleasing.  My main question is, how do I get the rendered profile patches to match the reference file patches?

Hello. Currently I don't have much time for the forums so support email is the best.

I'm not sure what you are trying to do here, but it seems like you are not trying to make a film simulation profile? That is you use a film scan to make a reference not of the real colorimetric colors, but the film response, and then use that file with a target shot of a regular camera, in order to make a profile that makes that camera look like the film? That's probably not going to work. Lumariver Profile Designer is not designed to be a generic LUT Creator software, but is designed to make camera profiles anchored in realism with only smaller subjective elements. It makes assumptions of how camera/scanner hardware works. This means that it always starts off with a linear matrix and make LUT corrections on top, which make robust smooth profiles, but requires that the system profiled is at large linear. If the behavior of the camera (or the reference file) would be grossly non-linear, that is the camera/reference does not work as real cameras do, the matrix matching will go haywire, and then the LUT correction, which is supposed to make only mild smooth refinements on top, will get into trouble. I haven't really tested these workflows but I wouldn't be surprised if you get crazy results or even if the software fails in optimization and get stuck.

For creating film simulation LUTs there are better tools out there, Lumariver Profile Designer is not intended for that purpose. It would require a different design which does not use a matching matrix at all but instead work with really dense targets (lots and lots of patches to cover the full gamut) and make a complete non-linear match.

If however I have mis-understood your workflow and you are really making a profile in the normal way, the best way is to use the archive project function and send a wetransfer/dropbox/whatever link to the support mail and I can have a look and see what goes wrong. The usual problem in that case is that there is some issue with the target photo (excessive glare, clipping etc), or that the grid is not correctly placed, or that there is some problem with the reference file not matching the target.

Hi Anders,

if possible - any approximate guesstimate about maintenance releases for LrPD and dcamprof with bugfixes ? thank you.

It's soon time for a new patch release for LrPD, I'd guess within a month or two. DCamProf is harder to estimate, as I prioritize supporting the commercial software. I have a new DCamProf release about 70% ready, it's more documentation than actual code left to do, so there will be a release eventually I just don't know when. In the autumn perhaps.

PS: as a side note - you need to change the licensing for LrPD again - it was cracked

For those that wants to crack software it's relatively easy, it's just about removing checks. It's a little bit harder now than the first release, random crashes here and there will occur if not all counter-measures were compromised, but it's not rocket science, that would just be a waste of my time. All popular software gets at least semi-cracked sooner or later, that's just the way it is, so I guess I can see it as a compliment. A key generator is different from a crack though (it means that you can make unauthorized keys and thus don't need to re-crack every new patch release that comes out). It was for that the software's key scheme changed, and that does not need to be changed for a crack, and even if it would have to I'm done with that now. Sooner or later a key is stolen and you need to block it for the next release etc, make new checks etc. The only comforting in this is that a cracker must spend much more time than I have -- for the sake of my paying customers I'm spending minimal effort on piracy counter-measures, instead I try to provide the best support I can and fix bugs (the actual ones, not the ones caused by a bad crack...). I prefer supporting through email though as I'm not much on the forums currently.

Hi,

I purchased Lumariver last week, it's something I've looked for a while so thank you to the creator!!

I'm having a lot of trouble creating a usable profile even when I follow the directions. I know i'm missing something crucial in the exporting process but just don't know what.

My results yield a profile where the midtones/highlights are crushed/destroyed severely, where the ICC profiles are not usable at all. I've emailed "[email protected]" a few days ago but haven't heard back.

I've attached pictures of my results. It's an exaggeration of curve to show how the different skin tones are treated. The Generic C1 ICC profile keeps all the colors very linear where as the new Lumariver profile handles them very differently.

My Gear:
Capture One - 11.01
Lumariver -  1.04  (Order # 69150422 )
Camera: Canon 5D Mk IV
Lens: Canon 24-70 f/2.8L II
Color Checker Passport

Hi,

I am sure Torger will chime in in due time.  In the meantime, what do you mean by crushed/destroyed?  Once you start playing with curves 'accuracy' is thrown to the wind: without the raw file nobody can tell you which of the two is more 'accurate' (including you:-).  If you are after 'accuracy' you should not use levels/curves/brightness/contrast at all - all of that should be set in the profile for the given capture/viewing conditions.  On the other hand you are allowed to use the 'Exposure Compensation' slider, assuming it works linearly (ACR/LR current process doesn't, I don't know about C1).

Did you follow the detailed steps in the manual? http://www.lumariver.com/lrpd-manual/#c1_workflows
Most time the target shots are mediocre. May you share your CCPP-RAWs?
