Rob de Loe: It's worth downloading the RAW (DNG) files and working on them. It's a different experience than what I'm used to, that's for sure. I shoot for black and white almost exclusively, but I like starting with a "colour" RAW file so I can work with the colour channels. There are no colour channels with a monochrome sensor, so if you didn't put the right colour filter in front of the lens when you made the shot, things are whatever tone the software in the camera decided to assign them. I use that tool too much to give it up easily. Even the ISO 12,800 files were quite usable, and tidied up nicely in Lightroom with some careful adjustments for sharpness and noise.

The files are pleasing, and working this way works for some folks. It's not for me, but kudos to Leica for being willing to be a niche in the nice and meeting a need.

"Grey tone" in the context of black and white is a common idea AstroStan. The word "tone" can -- but doesn't have to -- refer to the addition of colour to a black and white image.

But if you prefer, how about, "things are whatever luminance value is recorded by the sensor for each photo site and then converted to a value for the corresponding pixel in the DNG file that is output by the camera's software".

My original point, which I'm pretty sure most people understood, is that you only have luminance values in a DNG produced by a monochrome sensor, so users have a considerably narrower "range of possibilities" than is the case with a RAW file that preserves the colour information.

thx1138: If you want to see how lens tests should be done, read Fred Miranda's tests. He is a Sony user now but his testing approach is universal and is basically a more exhaustive version of Roger's approach that tests centre, mid -frame and corner performance and discusses field curvature etc.

Fair point dbm305. There have been so many posts on FM about Fred's testing approach that I muddled in some of the people who used it against charts.

Here's a link to Fred's approach in his own words: https://www.fredmiranda.com/forum/topic/1534737/0

My original comment to thx1138 took issue with the point that Fred's approach is "a more exhaustive version of Roger's approach". Re-reading that line, if "Roger's approach" is the grassy field, then OK, fair enough. When I wrote that, "Roger's approach" was still mostly what I've been reading for years on his LensRentals blog (MTF charts, OLAF)... but Roger's approach is also what's in Roger's post here.

Uhm, no. Not even close. Fred's test involves a chart that gets rotated to check the corners. He's the last person who will say his testing is "a more exhaustive version of Roger's approach".

landscaper1: Yeah, yeah, yeah, but when oh when is Adobe going to incorporate a modification to an existing tool, the gray cursor indicator employed with the Magic Wand and some other tools. THERE NEEDS TO BE A COLOR OPTION because gray is difficult to see against light colored and most gray backgrounds.

Been waiting forever for this. Still waiting.

I'd love to see more visible "pins" too. Almost all my photos are in black and white, so a grey pin is easy to miss.

On article Loupedeck+ review (135 comments in total)

I tried it for use with Lightroom but returned it.

It's a well-built piece of equipment, and the software is solid. But for the kind of work I do, I found myself having to go back to the keyboard and mouse far too often. I was hoping I'd be able to push my keyboard and mouse out of the way, but that's not possible. So I ended up with a keyboard, mouse, Loupedeck+ and my Wacom tablet in front of me -- which doesn't work. It's probably a much more useful tool for people who have to do the same basic things to a lot of photos (e.g., open, adjust exposure and white balance, crop, move to next).

Another thing to keep in mind is you can only set up a button to do something that is already built-into Lightrom. For example, if a function (like 1:1 previews) doesn't have a shortcut key, you can't assign that function to a button.
