    Yes, the last has its touching moment. Or anticipation of it :D

    Well, yes, I'm feeling bit like dr. Jekyll and mr. Hyde when looking my recent photos...
    Unfortunately it's slow season for birds here and not much light at this time of year. But maybe I find some shots from autumn time which I haven't posted yet here in some of next weekly shots.

    At first I thought that it was double exposure showing train on stop and moving and people were standing inside train.. Could be more intriguing without door part.

    It's probably software lens correction showing up.

    I like these 2 last images most, they seem to have this cleaniness and isolation what fresh snow implies, shots with just one main subject and without side distractions.

    Ok, so how do I apply the correction without getting those circles?

    If you ask me then can’t help with ACR. I think in some post-processing forum you can get more qualified answer.
    But in this particular photo I’d just crop bit from bottom and then darken rest of this cloth to hide this artifact.

    That looks to me to be an interference pattern between texture recorded in the uncorrected image and the distortion being applied to it as part of the correction. You see similar banding on repetitive textures (I'm thinking of things like weave in textiles or roofing tiles) if you downsample high resolution images without appropriate filtering or averaging. Moiré patterns are a similar sort of thing. The pattern is probably curved in sympathy with the shape of distortion being applied. Out of interest what lens was this shot with?

    Banding aside though, it's a nice image capturing the character of your dog.

    This one for me. The colours are nice and I like the way the clouds appear to be circled around the bird with a nice gap in them behind it.

    Congratulations on your purchase, it looks like a capable lens.

    I like the contrast of the well lit building against the deep blue sky in the first and some of the sculptures look very interesting too, making this a nice set.

    No idea what I'm looking at here, but I quite like it.

    I have to admit to being an anxious driver/passenger in winter conditions, so would probably have written off the day. Maybe a hangover from a nightmare journey on the M6, including a slalom at Shap, many years ago. I love walking in the snow though (not ice), so I'm envious of your snowy landscapes. These two catch my eye, the second because of the slight glow in the sky.

    I really like how you have just this one little window of sharpness. Excellent.

    This is neat! Most of the people on the other platform are obscured by the empty moving train carriage, while I think I can also see reflections of the platform that Daneland is standing on. Amazing what you can do without Photoshop, isnt it? 😀

    Forgive me if I'm not understanding what you are saying correctly and making a fool of myself with my words. I'm very limited on the technical side of things.

    Thing is, this isn't the first case of the same pattern happening and it's always on the sides like this, well the side that's the bottom in this case. I'm not 100% certain, but I think this only happening on this one side, which I beleive would be the right side if the camera is horizontal. I think it's somehow related to higher ISO. Don't ask me how, but it's these noisy images where it pops up. It shows up in the high resolution image when I make the correction tick mark. This export is downscaled.

    Lens is the Sony 30mm DT SAM Macro f2.8.

    I looked up some test data for your lens on DXOMark and it appears to have quite low distortion, which rules out my original hypothesis. It does however suffer quite significant vignetting at f/2.8, so with lens correction on ACR will be brightening the image in areas further away from the centre, with the amount of brightening added increasing the further from the centre the area is. This can make the image more prone to banding where the dynamic range is reduced, which is probably what you are seeing and you'll likely see this more in low light + high ISO situations, even more so if you lift the exposure or shadows when editing.

    Doing a Google search I found the following post on the Adobe forum which sounds like a similar problem to what you're experiencing (this is in Lightroom, but I imagine the underlying processing engine is similar). The last post is probably the most helpful.

    As the distortion on that lens looks pretty good in DXO's test, I'd probably turn off profile corrections for it when importing with ACR as they'll likely do more harm than good, unless of course the vignetting bothers you. I'm usually adding vignettes to help direct the viewers eye to the subject, so I don't think it would bother me too much.

    I appreciate all the leg work. Yeah, it only seems to be an issue in the low light stuff and trying to pull the darks up makes the issue more prominent. The camera is old so it's bound to have some special issues. The correction flattens the image out relatively well. Perhaps I can find a way to "blur" away the issue going forward.
