Green patches after using auto haze removal

After I apply auto haze removal I get lots of green patches in highlight areas. Did I set a highlight warning that I don't remember or is something else going on?

Problem or error

Hi Frans. Unless you have a new camera that requires a later version of ACR to open raw files, there is absolutely no reason for you to update it. I currently have Elements 14.5 installed in Elements 2021, and I expect I could update it to the latest version 15.x, using the workaround found here.

If you really need to update ACR for your camera model, let me know and I will confirm whether or not it is possible with Elements 2021.

About the color space bug with raw files in the Elements ACR (Always sRGB even if the choice is 'optimize for prints'), I have noted something strange while working on the jpeg file submitted by @Monte307 in that discussion:

https://community.adobe.com/t5/photoshop-elements-discussions/organizer-2023-photo-date-is-1-1-1601/td-p/13656660

When I open that jpeg, I get the warning dialog that the file has no embedded color space and that I have to choose according to the regular modes, optimize for print or for display. Everything works as expected.

When I try to open the jpeg directly in ACR, no warning at all and the result is always sRGB.

Maybe that could help debugging the issue?

A while ago, I had submitted the idea that the bug could have been the result of changes to enable the recent workaround to update the PSE ACR version manually, instead of waiting for an update needed both on the ACR module AND in PSE itself. If my guess was right, that would mean that the only satisfaying solution to get both the update workaroung and the choice of color space would be to include the color space choice directly into the ACR dialog, just like in Photoshop or Bridge.

Thanks everyone for the points raised in this discussion. I will bring the issues to the attention of the Elements development team. I would not expect the 16-bit problem to garner much attention, but the color management issue is certainly deserving of it.

So i tested the op's camera raw photo in photoshop elements 2019, the last pse version that allows one to open the camera raw file in the Adobe RGB (1998) color space and in 16 bits/channel running camera raw 12.4, depending on what camera profile is set in camera raw, you can still see the green areas in View %s below 50%.

Yes at 100% there are no green patches visible.

Several of my sunset photos exhibit the same after Enhance>Auto Haze Removal, but only if they are 16 bits/channel.

If converted to 8 bits/channel then no green with the Auto Haze.

And if i save the offending 16 bits/channel versions as psd files and reopen the green is gone no matter the View %.

It does look like the inability of camera raw in photoshop elements to open camera raw files in anything other

than sRGB like posted in the other forum contributes greatly to the issue.

It doesn't look like there is any permanent damage to the actual image, but just how photoshop elements is displaying the image at certain View %'s.

Exactly.

Three of us on the PhotoNet forums (one of three the OP posted this 'issue' on) have been dealing with this for almost a week.

It's not GPU or a display profile, the first area we suspected. It's simply some overlay preview that only shows up in 16-bit images and disappears when zooming in. It's not in the data.

I've thrown half a dozen different raws at this after downloading Elements 2023, but I can't make it happen for me.

The one attribute we saw with the raw supplied by Frans was it was 3 EV underexposed and then greatly brightened using Exposure along with some other edits and then ended up in sRGB from Adobe Camera Raw 'lite' used in Elements. At this point, there's no issue (other than massively under-exposed and over-processed sRGB). Only after running Haze Removal (auto or otherwise), does the green overlay appear at default zoom but goes away after zooming in.

I saw a really odd redraw from the 8-bit per color processed raw in the Haze Removal dialog on the same image. All this is outlined and shown and shown on the PhotoNet forum posts already provided.

There's no real issue here! Yes, there's some odd green overlay at a few zoom levels. The real problem is how it shows up (at least, for the one raw we three could make it show) on this very under-exposed and over-developed image.

If I had to venture a guess (which I hate doing) and based on some testing by John on that forum, this overlay matches the clipping overlay one sees in Adobe Camera Raw. It is almost like after Haze Removal, the OOG overlay (that doesn't exist in Elements) somehow appears. It could be some stray Photoshop code, but this is a guess.

Someone might be able to file a bug report, but damn, it's tough, at least for those of us on the other forum to come up with images ourselves that show this. Maybe you can provide some. But in the grand scheme of things, this 'issue' is benign. That we can't get Adobe Camera Raw "lite" to give us a rendering encoded into Adobe RGB (1998) seems a much more critical bug to fix and supply to customers.

Frans,

When you see the "Green" in your photo after using Auto Haze, if you view the image at 100% view (actual pixels)

do you still see the green?

Go to View>Actual Pixels

The green overlay disappears when zooming in. Nothing seen at 1:1.

I have version 13.0.0.612 and the update link is grayed out. Does that mean I'm current? Tried to download version 15.2 and it crashed the program and after recovery it still shows 13.0.0.612 as my version.

And what OS and version of Elements are you using?

Hi Greg. Funny thing is yesterday it worked fine, today it doesn't, without any changes that I'm aware off. I use PSE 2021 and Windows 10.

Another funny thing that started a couple of weeks ago, when I start up PSE, a screen pops up that asks me to sign in; never had this before. When I decline to sign in, the screen goes away and I can use the program without any hitches that I'm aware of.

If it reverted to the trial version, you will be able to use it for 30 days before you will need to sign in.

Go to Help > sign in from the Editor menu and sign in.

Elements has limited capacity to edit in 16 bit. This may be one of the limitations.
You may want to see if updating your graphics driver changes anything.

It's his document (which I got a copy of). Why I have no idea, I've opened more than half a dozen 16-bit images, in various color spaces and tones ranging from 0/0/0 to 255/255/255 and can't reproduce the green overlay that I DO see in his odd PSD. It isn't in the image data. Zoom in, it disappears.

Something wonky in the image, what and why it shows this, still not clear.

Disabling GPU makes no difference. And with his 8-bit per color doc, and only that document, the Haze dialog goes nutty too:

Interesting; it happens when in 16 bits/channel mode, but doesn't happen in 8 bits/channel mode.
