Hidden Menu on M8

Recommended Posts

Advertisement (gone after registration)

I found the access info for the hidden menu and now I have a new file format option in the quick menu.

 

 

Anyone else have this?

 

Also, if I select it and it's not there by default... will that cause an issue? So this RAW is what exactly? CR2?

It's not hidden, it is just an standard option to save a JPG file as well as the raw DNG file.

 

You can use the JPG file for a guide when you want to adjust your raw file in post processing.

Okay -- I dont think it's standard... what IS standard is the DNG+JPG. The "JPG+RAW" option only comes up once I access the debug menu...etc. But when I take a picture a strange format pops up and not an actual picture preview.

All M8s have this hidden menu i guess but the .raw files cannot be converted by usual raw converters. Never tried with Lightroom nor Aperture though.

Sorry, all digital Ms have this option in the "set" menu, always have had. It is, in fact the only way to get a B&W preview on your LCD on the M8 and M9.

Btw, there is a hidden menu, but it is for service purposes and does not access the file format.

The "JPG Fine+RAW" option is hidden indeed. Can be accessed after opening the "Body Debug Data" menu but the format of .raw files is unknown as suggested above.

What we are missing is that he highlighted another menu than the one he means. ;Yes - jpeg+raw is in the debug menu . It contains uncompressed raw data. ( See LFI 1 or 2 from 2007 if memory serves.) Those data can only be read with specific software which Leica does not make available to outside parties.

Maybe Bibble can convert it.

The OP's pic was self explanatory IMO.

 

That's exactly what I mean... perhaps it's connected to the other option in "the hidden menu" for using "Two Channel Corr."?

 

I know Kodak made the sensor for Leica M8 and the option is there to use this all but I guess Leica never followed through when Kodak folded and the camera war began?!

I have not my M8.2 with me here but suffice it to open any hidden menu to access the JPG fine+RAW opion if memory serves.

I know very well the menu for repair.

 

It was most definitely not obvious that op was referring to that menu IMHO.

 

An image of that repair menu would have been the obvius to post, not an image of the std menu...

 

And to suggest shooting while in that menu would be taking a big risk IMHO.

 

Good luck shooting unreadable RAW files!

 

Sorry I have wasted your time

I do not see it on my M9. How does one bring it up?

Thanks for your input... I am not planning on using the new Standard Menu option that popped up on the screen after entering the Repair Menu. I was merely asking -- nice, good, more experienced Leica users -- to put it plainly: WTF?

 

What should've been obvious, since that is what people are choosing to focus on, is that there was a new option in the standard menu which doesnt appear when you very standardly turn the M8 on. These are just questions and i appreciate all of you who answered my initial post. Really, thank you!

Hello everyone!

Till now I haven't participated in the forum so this is my first entry. This RAW+fine-jpg option made me curious so I had a go with my M8 and fiddled a little bit around with the resulting RAW file.

 

I was able to extract the image data

As far as I can see from my 4 test images the image dimension equals 3968x2647. That is a few pixels more than the jpg file (3936x2624).

Additionally the values range from 0 to 16384 (which make it 14 bit data in a 16 bit file).

Interestingly in my first test shot which was captured with ISO 1250 the data also contained values from 0 to 16384 but a lot of the values in the histogram were empty. In fact only about 2048 unique values were available (that equals 11bit). So that might explain to some extent the loss in image quality (I guess).

 

The next step would be to put the raw data in some file which could then be debayered and processed further. I only have a mediocre debayering method at hand right now so the result's rather appalling. Well not that bad but you know...

 

To wrap it up:

shooting RAW+fine jpg enables to capture the 14bit sensor output in most cases. The file size increases to 20MB+some for the jpg. The image is a little bit larger in both dimensions. Postprocessing should be more flexible as there are more discrete values to start with (compared to the 8bit DNG).

 

If someone is interested in further work or information please let me know!

 

Cheers,

Arvid

 

PS: sorry for the long post!

      Probably already answered many times. Sorry for the repeat.
      Does anyone know whom to contact at Apple in regard to getting the D-Lux 7's raw files recognized in MacOS High Sierra? (2011 computer; High Sierra is latest compatible OS.)
      Apple says to contact Leica because the camera files may not be compatible with the OS. That doesn't ring true to me...
      Or would it be best just to forget about it? 
      Thanks!

      First time post, be gentle. 
      I want to bring my raw files from Monochrom into silver efex. SEP. But it will only accept RGB. Will this lead to loss of quality ? When I scan my black and white negs I do so in greyscale and that’s  perfect for printing to black and white paper at Metro. 
      It seems to defeat the object of the Monochrom if I have to convert to RGB ?
      Am I missing a trick ? What say you ?

      Update 26. November 2019: Das hier ehemals verlinkte Forum existiert nicht mehr.
      Im Systemkamera-Forum gibt es aber jetzt ein eigenes deutsches Capture One Forum

      What is the benefit to shooting JPEG and RAW?
      I am starting to get overwhelmed by having doubles of all pictures, not to mention the additional space requirement.
       
      Does anyone shoot only JPEG? Why?
      Does anyone shoot only RAW? Why?
      Thanks!

      Hello all,
      I just got a leica Q firmware version 2.0 from my friend. He said he purchased it in Hong Kong.
      When i'm using this Q, i found that it's slower then mine when i try to switch it off, and the leica logo become a exclamation mark before it turn off.
      The most interesting thing is that when i try to update the firmware from 2.0 to 3.1, every thing is normal but the version number shows 3.16 after it's updated.
      of course it keeps the hidden menu here until i go to the service menu and reset it.  
      anyone had seen it before? and know how to access the hidden menu again? 
      thanks alot!
