I stepped out to photograph the comet last night. In addition to capturing more of a scene, I tried to use my 70-300L to photograph a closer up image of the comet.

Processing the images in LR, I saw this:
Small-3644-2.jpg

Looking at the RAW file itself, I do not see any pattern noise. I have tried some steps in LR that lesson the pattern, but, I still see a pattern in the exports.

To see if this is an LR image, I processed this of the same file this morning using Photoshop:
PS Small-3644.jpg

Granted, this is much less exposed, but in playing with it, I do not see the same pattern noise.

Playing with this further, I can eliminate it if I turn off the lens profile in LR for this lens, the EF 70-300 L.

Small-3644-6.jpg

But, I do like to travel with this lens and would prefer to not have to do that with all my images.

Any other thoughts on how to address this issue?

I've never seen that, and I used the 70-300L a lot with my DSLRs...but only with DxO PL as a RAW converter.

DxO had the same bug a while ago, making denoiseHD run on the CPU instead of the NE worked around that. After blaming Apple for a few months and saying Apple should fix it, DxO issued an update that completely fixed it.

Still running DxO on my personal Mac, which is a 2019 16" Intel Core i9, not Apple Silicon. Still runs fine, really, but I suspect I'll get one of the new M4 MBPs when they launch later this month. The R1 notwithstanding, Canon isn't giving me any RF lenses that I want to spend my money on.

It looks like the timing of my new job would work out with the timing of the M4 launch, so I’m hoping to replace my 2020 i7 mbp with an M4 one. First world problems :)

My wife’s M1 air runs circles around the i7 when it comes to LR and DxO, which is why we’re bringing that one on vacations. A very large performance gap for models less than a year apart.

First world problems, indeed. I have an M1 16" MBP for work (started out with a 16" i9 identical to my personal one except for the color, but that one had a RAM module fail and the 3-5 days Apple needed to replace the logic board was not compatible with me leaving the next day for a conference, so I bought the M1 on the spot). I haven't processed any RAWs on it, though.

Either way, I don't process RAWs on vacation. On family trips, I'll bring a 'loaner' 14" MBP from/for work and back up RAW images to that for safekeeping, but I don't go through them until I get home.

It’s mostly culling for me and seeing if I want to reshoot something, serious editing happens at home, on a faster desktop machine, with a nice and large screen.

It’s nice to have the option of doing all the editing on bad weather days, it’s amazing how fast laptops are nowadays for photo stuff.
