Hi,Terse,What are you using to develop your raw captures? (I usually use Lightroom Mobile. I try Raw Power now and then, but I still get better results from LR.)
I rotate through a lot of camera apps, hoping to find one that suits me perfectly, but no...Hi,Terse,
Now I gotta ask you, what raw camera app are you using? I miss the histogram not provided by LightroomMobile, and find the zebra stripes to be less-than-accurate in finding the ETTR exposure.

Hi,Terse,I rotate through a lot of camera apps, hoping to find one that suits me perfectly, but no...
Most often I use ProCamera or the Lightroom Mobile camera (either Pro or HDR mode). I have the sense that zebras in general are overenthusiastic in all the apps I've tried. The histogram in ProCamera seems more accurate, but it's so damn small (and I mostly shoot outdoors in daylight, so the screen's often hard to read anyway). I haven't found histograms in other camera apps useful at all -- no clipping indicators as in ProCamera. I've tried Halide, ProCam, ProShot, Chromatica, Camera-M, Moment cam, and CameraPixels (which is excellent for other things, like focus stacking). Undoubtedly others I've forgotten.
ProCamera drives me nuts at times. As Nichols said in the Ultimate DNG book, it lets you make the proper white balance settings for uniwb, but you can't save that as a preset. And once you have it set up, if you shift lenses, the settings are wiped out. Then if you shift back to the original lens, those settings are wiped too. Argh.
I have tried his TLC method also, putting the two colored gels over the lens, and it works well, but those gels scratch and buckle if you just look at them sideways.
Just an old joke based on my initials TRS. Nobody's ever accused me of actually being terse.definitely not terse
So how did you go about determining the extra dynamic range? Have you done that with your phone? I've been thinking the same thing but hadn't figured out how to go about it yet.Hi,Terse,
Your detailed- and definitely not terse- response is much appreciated. I had hoped that the excellent exploded histogram of 645Pro would end my quest... but no such luck.
The ones I’ve tried so far are Halide, LightroomMobile, ProCam, ProCamera, Moment, 645Pro, Manual, and Raw+.
The search continues.
I got into UniWB several years ago with my Sonys, but, in my hands, tho logical and functional, it felt more tedious than simply and easily determining each camera’s extra raw/accessible DR and then being sure to use it.
Haven’t tried his TLC method yet. Not sure I want to fiddle with the (imagined ?) tediousness of the filters.
I do appreciate your insights, obvious experience, and comments.
Thanks, and best regards,
Dave
Hi. TRS,So how did you go about determining the extra dynamic range? Have you done that with your phone? I've been thinking the same thing but hadn't figured out how to go about it yet.
The uniwb and TLC do produce good results but are definitely fussy enough that I don't use them that often. Once I got the proper gel filters from eBay for the TLC, I had to figure out a way to attach them so that they stayed flat and could be easily removed. I tried adding them to a 37mm filter adapter from Moment (I have a Moment case) and adding them inside the case, but both ways the problem was keeping the gels flat. I got the best results by taking two thin pieces of cardboard, cutting holes in them to match the lens opening, using them to sandwich the gels, and then sticking them to the phone case with restickable tape. The gels stayed flat that way, though the cardboard definitely gave a funky look to the phone (not in a good way).
- my point was not the “differences in lenses” but that the wide and tele cameras (the two from which raw files can be captured) have their own, see Ed paratr sensors, each of which must be tested.Aha. I stumbled upon the testing method yesterday, but I hadn't thought of allowing for differences in lenses, ISO, and white balance. Back to the test lab.
I've been using CameraPixels Pro to shoot the tests because it can do bracketed exposures in increments as small as 0.1 stop. It does shoot over and under brackets in one go, so I end up with a bunch of underexposed shots that I just delete.
And once you've figured out the extra range available, the actual shooting method would be to expose the scene properly according to the on-screen histogram or zebras and then dial in the extra range by adjusting the exposure compensation?
Also, a little explanation of "tonal normalization"?
Speaking of brackets... I'd think that once you have the extra range figured out, you could shoot a bracket that would give you a properly exposed JPG and a properly exposed DNG (along with an underexposed throwaway), although maybe there's no use for the JPG if you're intent on DNG.
