The use of the term flat field to refer to phenomena relating to electronic image sensors is a bit confusing, since the term also applies to a strictly optical characteristic: a lens's plane of focus.

Not sure about that , John.

Of interest to those using hybrid lens/camera combinations (aka adapted lenses) Adobe has now incorporated their "Flat Field Plugin" within Lr 8.3.  Sean Reid explains all in a comprehensive guide:  https://www.reidreviews.com/examples/flatfieldnew.html

It would be very nice if Adobe would incorporate these corrections into their lens correction profiles. It would also be very nice if Adobe would offer a feature to move lens corrections off axis, to account for the movements of perspective control lenses. Capture One at least offers this for lens distortion.

Hi David,

While I'd agree that that would be nice, I doubt that it would produce optimal results (and I would readily agree that my preferred standands exceed those of normal/average people). The reason is that each, and I mean EACH, lens is a bit unique.

So while adding another step(-up) to 'average' image quality control, I (don't/)wouldn't object if offered as an option.

I'm just being realistic about this, while I agree (which is easy as a licensed Capture One Pro user looking for ultimate quality and already having those options), it probably/apparently doesn't serve a concern of most LR subscribers. I'm okay with that, that's one of the reasons I abandoned LR, and several other Adobe offerings. While it serves a lot of people, it simply doesn't serve those seeking the best.

As an anecdote, I vividly remember a 'discussion' with a prominent and widely respected National Adobe representative for my country (The Netherlands), when asked when Adobe intended to improve the resampling quality of Photoshop, he said there was nothing wrong with it, period. At roughly the same time, I was investigating opportunities for improvement with people who would later be contracted by Phase One, who did value progress more than short term subscription earnings.

Cheers,
Bart

Adobe just introduced enhanced detail, texture and flat field; These are all options a lot of photographers do not care about but the ones looking for the best possible quality...
I will have a look at C1 again soon, but some things I did not like about it in the past:
1 too vivid colors.
2 uneven sharpness across the image. (for instance hair being cluttered (as Trumps) at some points)

What i do not like about Adobe Photoshop ( since decades) is that it makes very bad use of the computing power of the hardware, especially in repetitive batch tasks.
(making a bunch of photo's smaller it does one at the time- only one core is used- and i have 10, making the process about 8 times slower than possible)

You're probably right about flat field, a bit less so about enhanced detail, and I can only assume you haven't even tried texture before making that comment.

Not right about flat field if the goal is the best quality image data:
https://en.wikipedia.org/wiki/Flat-field_correction
Flat-field correction is a technique used to improve quality in digital imaging. The goal is to remove artifacts from 2-D images that are caused by variations in the pixel-to-pixel sensitivity of the detector and/or by distortions in the optical path. It is a standard calibration procedure in everything from pocket digital cameras to giant telescopes.

I utterly accept there are lots of photographers who's goals are not ideal image quality. It's why so many can't even figure out how to expose for raw; exposure photography 101!

you are right;  texture is a big plus for everyone...
It is going to replace the use of clarity in many situations.

Not replace. They work hand-in-hand. Fibroids doesn’t replace saturation. Different tools for different needs. The Adobe blog has some good examples where both texture and clarity work in tandem.

I suspect you mean "don't", not "doesn't", but I'm unsure of the relevance of uterine leiomyomata.

..and replace in the sense there was no texture before and looking back it was often the better choice over clarity.
i understand they can work together....

I downloaded 8.3 a couple of days ago and I am having a problem making the round trip to Photoshop and back to Lightroom. I use Control-E to move the image to Photoshop and do whatever I need to do and in the past I could simply close the image in Photoshop and it would automatically be saved as a tiff.

Now, if I do that Photoshop freezes and must be killed in the task manager, then reopened to continue. I can avoid this by saving the images in Photoshop using Control S before returning to Lightroom.

Did the upgrade to Lightroom 8.3 somehow alter the relationship between Lightroom and Photoshop?

Has anyone else experienced this?

My workflow is round tripping just as you have described and it has been unaffected by the upgrade on my system.

Thanks Martin. The only change I've noticed is that, after working the image in Photoshop I must first click Save or use Control-S and then click to close the image. Before, just closing the image would automatically save it. Not a big deal but my system is freezing Photoshop completely when I do it the"old" way.

Oh the magic of rebooting the system. Problem solved. Lightroom and Photoshop are behaving as before.

Correct me if I’m wrong, but flat field correction is an old hat in Lightroom. I remember that Michael showed this feature many years ago. I think it was in the video to version 4 of Lightroom.

Not reales, as far as I remember we had to download it from Adobe separately, but it was to be integrated into Lr as a plugin.
So, the tool is pretty old and the integration has been improved...
