Adobe update for M240


Recommended Posts

Remember when you do create a profile, to use a fixed white balance, otherwise you can get some very odd results. If you are using a dual profile, I think you are supposed to use the same white balance for both images of the CC24 swatch card. I don’t have my card and the instructions with me in France, so perhaps others would comment on that.

ACR has got huge. Unpacked it is now over 500MB. I remember back in the late nineties, when I had a 33K BAUD dial up modem, it was about 6MB and that took about 20 minutes to download from the Adobe FTP site.

Wilson I haven't made a custom profile for a while but from memory the dual illuminant one required your source samples to be at 6500K and 2850K for best accuracy.

 

Even assuming that the variables were not.... in theory this process will only give you 'correct' in identical conditions, with interpolation otherwise of course. Then you get into the complexities of hue twists.

 

At least I never made one for my M9 that worked as well as the Adobe originals. I even had one made by one of the most senior engineers at Adobe.

 

But 'correct' and 'best for application' and preferred' will we hope at least overlap ;-)

Geoff,

 

The daylight dual illuminant profile I made right in the first days of the M240 was miles better than what LR offered as standard at the time but presumably they have improved in the meantime. I was using LR at the time as Phase One did not do a profile (ICC) at all for the M240 until sometime later. Now that you remind me, I did use the two fixed colour temperatures but not quite as far apart as suggested. I did one shot in bright direct sunlight and one in a lot of shadow. Now that C1 has a fairly good ICC profile, I have stopped using LR again.

Wilson, I thought the point of dual illuminant profiles was to have different light sources (e.g., daylight and shade). Otherwise what is the point of "dual" illuminant? Or am I misunderstanding this whole thing (not unusual)?

Yes indeed. What I could not remember but Geoff corrected me was whether you used the same colour temperature for both shots or different. As he says, the recommendation is 6500ºK and 2850ºK but that is when you are using very widely differing illuminant bases for the dual profiles. I made different dual profiles with narrower bases for sunlight/ sunlit shade, cloudy/cloudy shade and tungsten brightly illuminated/tungsten shade. I just felt these would be less of a compromise than a very wide based dual illuminant. They seemed to work fine before I gratefully returned to C1, when the proper M240 profiles arrived (I cannot get my head round LR’s library system and general way of working in spite of years of trying). C1 and Aperture I found dead easy, so it must just be that the LR developers’ brains have different wrinkles to mine.

Naive question since I do not use profiles, but do they affect DNG's or only jpegs?

 

They affect the JPEG or TIFF that you convert from a DNG or RAW.

Everything you see on the screen has to be converted from DNG file first. In short, when you look at a photo in LR a certain camera profile, together with the raw engine, must be used to convert the dng data into something a display can present you. In LR this profile is either Adobe's default one, or you can make a custom one by using a color checker for example.

 

Per my experience none of the methods involving Adobe didn't give me satisfying results as oppose to C1, where the default profile that came with the software did.

 

This is my personal opinion, and some are quite happy with LR. In my case I am not sure whether I prefer C1 due to it's camera profile, maybe it is related to the raw conversion method as well.

Apologies for going off-topic. I am told that i can download the latest version of LR/PS as i have recently purchased an M240, but i cannot find any reference on how i do this... ?

 

When you buy a new M240 in the documentation that comes with it you get a TAN number. Register your camera on the Leica Owners website and follow the link to get your software license number which is sent to you by email once your TAN number has been accepted. You can then download the latest version of Light room and register it.

This is the missing beast....it did not jump out at me when i unboxed and then read the manual and passport?.... where does it hide? :confused:

As I am away from home at present I cannot check my Leica paperwork but from memory I think there was a sticker on the back of he Passport application card - the bit you keep- not the bit you send in. If you cannot find it in your documentation perhaps an email or phone call to Wetzlar quoting your camera serial number might help.
