blurring)Īlso note that if you are using the export for Web path, the rendering approach is typically defaulted to the last one used with Image Resize.ġ) For some reason, image 3 that your provided for some reason not determined as of yet, has a repeating horizontal pattern at the pixel level as opposed to normal randomized noise (this is the starting root of the problem)Ģ) The downsizing process with the nearest neighbor rendering option amplified the horizontal pattern due to the specific resizing percentages.

So assuming you are using Photoshop, I would bet if you change to rendering option that the problem will go away without any other steps (e.g. When I used any of the other algorithms available in the image resize process, none of them created the banding. Key discovery though is that the only way I could make the banding occur was with the "Nearest Neighbor" rendering option (which is an uncommon render to use in most images except in special cases). This is a sure indication or a resampling issue with the image resizing involved causing Moiré issue. It turns out I could duplicate the banding quite easily and even make it worse or better by changing the magnification just slightly. The second image was 55.33% reduction in size. Using the original image, to create the first image posted was a 51.35% reduction in size. Each image is a different crop as well as image resizing. To duplicate your issue, I took another look at your image in detail.

Interestingly, when I decreased the Sharpness to -100 for the sky, those areas did not have bands.Īlso, the picture shows up as 9.4 mbs on my Mac, but somehow only 8.9 mbs on my phone and 9.1 mbs on my office PC.Īny idea as to what might be causing this issue? Is it a corrupt file or is there something wrong with how Instagram and Tumblr are reading this file? The bulk of the banding is around the Taipei 101, which is where most of my recent edits took place. However, the final, uploaded image is always fine and the issue doesn't occur at other sizes.

TOPAZ TEXTURE EFFECTS BANDING WHEN EXPORTED PC
On my work PC and on Instagram, I can see the bands at specific sizes when the photo is uploading on Tumblr or in the editing phase on Instagram, and they stay that way while in these stages of being uploaded to social.
TOPAZ TEXTURE EFFECTS BANDING WHEN EXPORTED MAC
On my Mac, the bands appear briefly when I enlarge it, but the Mac always corrects it so that the bands only appear for less than a fraction of a second. I'm encountering an issue with seeing horizontal bands when trying to upload a photo to Instagram and when viewing on an office PC when I enlarge a recent pic to a specific size.īelow is the photo I recently re-edited, and it's fine when I enlarge it on my Mac either as a file or through the Photos app.
