[Samsung Galaxy S23 Ultra] Ubacher:
Note that the dng files produced in pro and Expert Raw mode are not

RAW images. They are the processed images stored in DNG format - which allows higher bit depth

(12 bits)

This is especially noticeable with digital zoom: The resulting images are always

12 MP (3000x4000)

Nuisances:

When one selects 50MP one can not change to other cameras. One has to set 12MP

again to do so. This does not make sense to me.

One can not specify Author and Copyright holder in the App.

The GPS data should also include the camera image direction

since this is anyway available in the phone.

When reviewing a photo taken with ExpertRaw on can not enlarge it to check for sharpness.

One has to exit the app and use the gallery app to do so.

The ExpertRaw images are at times over-sharpened. ACR (Adobe Camera Raw) allows some reduction of

the sharpness. One can not select a lower grade of sharpening like one can for the pro mode.

(Using camera assistant)

Selecting different cameras can be difficult in ExpertRaw. Touching can result in focus/exposure lock instead of camera selection.

12MP images from the main camera are poor. One would expect them to be 50 (or 200) MP images downsampled to 12MP.

This is not the case. I suspect this would slow the capture/processing.

I compared a 12MP identical image from an S8+, also 12 Mp and it is no better.

I find the 10x camera selects a slower shutterspeed than appropriate for the lens.

The camera (on automatic exposure) makes frequently images with ISO set to 10.

The settings allow the lowest ISO to be only 50. Why?

Errors:

Expert Raw images 50MP are more than 3 stops underexposed!

Digital Zoom shown as 1 3 10 and wrong 1.2 instead of 0.6 for the ultrawide camera.

Actually should this be 0 when no digital zoom is done.

The digital zoom value - as shown - is only added to the jpg metadata. It should also be

carried in the dng metadata. This is needed to know if one can apply a lens profile to the image

when processing in ACR. Note that Photoshop ACR has valid lens profiles available for all the lenses.

---------------------

Very little attention has been given to propper Metadata - shameful

Wishlist:

A simple way to reset EV to zero.

The camera selection icons farther apart.

For users who need reading glasses: a way to have larger icons/text.

Allow the button on the pen to take picture in ExpertRaw app.

(Currently only the normal camera app allows this)

Allow the Lightroom camera to select all lenses.

Have metadata which shows which app/setting was used to produce the image.
