Good Lord, you are anally compulsive about post processing routine! I thought I was bad. Adjusting contrast for highlights, midtones, and shadows using masks is really going the whole 9 yards as far as dynamic range retention is concerned. How many photos can you process in a night,..... about two?😉

😀 😀 Actually it goes quite fast. It is not so much a dynamic range thing, as it is a tone curve refinement. In a way it is a variation on tonal mapping, the newest trend in PP.
I got into it as a personal challenge to see if I could develop a JPEG file to equal the mythical RAW development results. In B&W it is like the old dodge & burn freaks (AKA Fine print makers), who could work a negative to the nth degree. I used to print Cibachromes from slides, so the DR from digital is a delight🙂

Anyway, the more I delve into the intricasies of RAW processing, the more I know I don't know.

I think that shooting similtaneous JPEGs to compare with my own output, might be an interesting exercise. If the in camera processing can do a better job than I have been doing, I think I will kill myself'.

Just kidding

Please don't😱
When I do RAW development, it reminds me of developing color film and wondering if the chemicals were mixed right, hadn't oxidized, weren't too old, and if the temperature was holding steady🙄 When I goofed that up, I had a printing problem for sure. Of course, I learned all that the hard way😱
Using in camera processing is like getting film machine processed at a lab, not the best, but consistant. What using the camera's processing requires is good basic photographic skills to nail the exposure, so it is a good learning tool (or relearning tool in my case😱 ) When you do RAW, you can begin to appreciate the folks at the Pro Labs. Learning how to tweak instead of mangle a digital image is another matter😉

Rex,
If you have any interest in the tri tone process, here is a link to a tutorial. The software is Picture Windows Pro, so you might want to skip that and see his samples. http://www.ncplus.net/~birchbay/3tone/3tone.htm
Somewhere I have a Photo Shop link to the process. I'll see if I can find it.

I looked at the turorial and it looks very interesting. I've been working slmost entirely in ACR, not using any masking techniques available in Photoshop proper. Clearly rescueing highlight and shadow details require me doing that.

What I'm doing now in RAW is the wet darkroom equivalent to film development. What you are doing is equivelent to printing. I was doing that in Photoshop with TIFF files but when I discovered RAW I have been drawn back to the basics of "film" development and have been neglecting the necessary finish work in Photoshop itself.

I am very interested in any information you can send me regarding the process as executed in Photoshop.

Perhaps you can send me a PM as we have done a pretty good job of hijacking this thread.

UPDATE:

RFF M lens owners. Rangeinderforum.com is in the process of acquiring the necessary equipment and data to encode M lenses with the new Leica 6-bit code for use with the upcoming M8.

We have not completed this process yet nor have we modified any lenses. We are waiting for the M8 to be released and approval from a patent attorney before we commit 100% to this task.

Once we get the green light, the service will be offered to RFF members at a substantial savings. RFF is also working on applying the code to the Zeiss ZM lenses. If you are interested in this service, please send an email to rangefinderforum @ gmail. Com For more information keep an eye on this thread:
 
Jorge,

Be quite careful here, '100% approval' from a patent attorney is absolutely zero assurance you are safe. IMHO you better tread very lightly here and weigh the potential economic advantage to you against a not unlikely lawsuit somewhere down the road. Win or lose, it is very expensive.
 
Dear Jorge
This sounds great for the US but Im not sure i would be sending my lenses from the UK. I suspect very few people are sending lenses for 'chipping' at over £100-a- pop. Clearly your deal would be a lot cheaper. I have had a few conversations with Robert White who are a very well respected pro dealer in the UK and they tell me that they have been using the wide Zeiss lenses (unchipped) and with absolutely no propblems at all. (Robert White himself aid he was having trouble retrieving the demo M8 from his staff to show to customers!)
I too wonder how you will get Leica's approval for this.
I await with interest

MORE INFO Feb 2007

Stefan Daniels, Head of Production for Leica Camera explained at the Wetzlar LHSA meeting (during Photokina) that the M8 Lens bar coding system is patent applied for. RFF will NOT encode the M8 bar codes.
