Photoshop :: Banding At Magnification Lower Than 64 Percent
Mar 24, 2013
When I'm viewing photo at zoom lower than 64% banding kicks in. At zoom higher than 63% everything smoothed out. It's giving me a hard time when I'm trying to retouch big files at lower magnification because actually I cant know until I zoom in do I'm removing something what exist or actually not!
I know it's an issue regards do displaying preview of 16bit image as 8bit image. I was checking this in many ways and it appears only in 16bit mode. I'm quite a quality maniac so I always retouch in 16bit mode and ProPhoto color space to give myself a bit more room to play with post production.
Please take a look at snaps made using windows snipping tool. All images are in ProPhoto color space but I also have tried this in RGB and it looks quite the same.

I'm on windows 7 ultimate 64bit, 64GB memory, Intel I7 processor, geforec GTX680 GPU.
Gradient and color banding are very apparent and exaggerated until I zoom in to 66.6%. It even hangs for a split second as if it is solving a new render at a higher quality. This is getting frustrating as I've found myself manually trying to clean up issues that actually aren't there when I zoom in close enough. These issues are expecially obvious when working with skin using several degrunge techniques and dodge and burn on a softlight layer. It does not seem to matter what display I use.
If I commit all adjustments to a new layer the problem goes away. I'm working on a Eurocom Panther 3 running Windows 7 64 Ultimate. I have a hex core Intel processor and 2 Nvidia 580m in SLI, though I am aware that is not used in Photoshop.
My printer told me to add 5% C 5% M and 5%Y to my 100%k channels as without it I can see the black comes out a little/touch fury on things like small thin text.
Is this the same on all other colors too? Eg. say 100% Cyan color, should I add 5% M, Y and K?
Been running PS CS5 successfully for a couple of years, then all of a sudden I can't work at magnifications other than 25% and Actual Pixels. The image disappears and I only see the checkerboard. There was a Windows update I ran on April 10 that included an update to the graphics card, which I thought might have been the culprit, so I uninstalled it. That didn't fix the problem, so I updated it again. I couldn't see anything else in those updates that should affect Photoshop.
Here is what I've tried so far:
I updated my graphics driver (NVidia GeForce),
Trashed Adobe Photoshop CS5 Prefs.psp (which crashed PS completely when I reopened it...luckily I kept the old prefs file on my desktop and dragged it back in),
Made sure Photoshop was up-to-date.

I'm going to be purchasing a new PC computer system in the near future; which will be loaded with 64-bit Windows 8 or 8.1. I'm presently using CS5 & CS6, both 64-bit versions, on existing computers that have Windows 7.My work is photography and I do a LOT of masking. In order to see what I'm doing while creating masks, I typically use CS5/6 image magnifications of 300% & 400% with a monitor that has 1680x1050 resolution. On another monitor with 1920x1080 resolution, I have to increase my working space magnification to 400% & 500% to get the same "view size" of my work. That's because the "view size" decreases as the monitor resolution increases. My main problem is that CS5/6 will not produce "smooth" images at a magnification over 500%; as the image is pixelated to a degree that I can't accurately cut a mask. Therefore I need to do my work at magnifications of 500% or less, but I need a "view size" large enough so that I can comfortably see what I'm doing.
For my new system, I'm considering monitors with 2560 horiz resolution. In order to maintain my on-screen "view size" of the 1680 & 1920 monitors, a 2560 monitor would probably force me to use CS magnifications in excess of 500%.
What can I do such that CS will produce "smooth" (non-pixelated) images at magnifications greater than 500%? Or...what can I do to make the entire CS window appear larger; so the "view size" of the 2560 resolution monitor is comparable to a lower (1920, for example) resolution monitor?
In liquify mode the picture is not visible at 100% magnification and above.It's perfect between 25 and 66%. If I turn the hardware acceleration off it works but slow. Doesn't work with PSD, jpeg, 8 or 16 bit. I did reset the PS. It had been working during the morning and stopped to work hours ago despite nothing happened: I haven't installed or removed any software. My PS is clean, I don't use any add-on or 3rd party filter.

CS5 has suddenly started opening files with the default magnification of 0.12%. This means images appear as tiny specks of dust in a very small window and typing 'cmd-0' has no effect. Typing 'cmd-1' does enlarge the image to actual pixels but the window stays postage stamp size and has to be manually dragged larger. Typing 'cmd-0' again at this stage returns us to 0.12%.
Resetting the zoom tool or anything else I can think of has no effect.
Basically when I export a PDF and open it in acrobat it opens 'page width' I'd like it to be 'fit page' so the customer sees the whole proof, not just the top of the page.
I don't see any settings, but I only have 1 fully functional eye so I thought I'd ask you all.
IF there isn't a setting for it, can the fine people at Corel add this setting in the export dialog in the future some time? That'd be awesome.

I have noticed that files opened in Paint.NET 3.5.8 tend to pixelate at higher magnification. This occurs regardless of size, format or resolution. The same files opened in other Adobe, Ulead or even my MS file viewer do not do this.
know this is probably somewhat of a techy question, but I'm really alarmed at how much CPU 3D rendering uses in PS CS6. My computer just howls! Can I get some tips, apart from the obvious hardware upgrades? Here are my hardware specs for my computer:
Dell Studio XPS, 12GB ram, Intel Core i7 930 2.8 Ghz, GeForce GT 630 4Gb Aside from that, PS also uses over 6GB of memory at times. This also seems extremely high to me ??
When I open up a psd files they open at 0.13%. Really small. Today they all opened at this size. I'm using CS4 on a Mac Pro running OS 10.7.5. How do I get files to open at 100%.
My masks are all about 50 per cent in opacity lately but I can't see any control or method of making a 100 per cent mask. See above-- The A was masked by a black brush at 100% opacity. The Properties control has opacity set to 100%
I'm in the process of scanning in old photos and retouching them in Photoshop. I have many books on the subject and have been using Photoshop for 2 years now..
I'm curious as to what percenage are corrections made. When you look at a photo at 25% of the size it looks one way, but when you zoom into 100% it's obviously another.
Just upgraded to PS CS6, and am having a problem manually entering a value for the magnification level in the status bar (same goes for Navigator panel).Is it supposed to automatically zoom to the amount entered without hitting enter/return? For example, if I want 25%, the box will read 2%5 and tells me my value is invalid by the time I hit return (the document will go to 2% automatically before I hit the 5). I can find nothing on this anywhere online, and the documentation mentions typing a number then having to press enter/return. Is this a feature? A glitch? Can it be disabled/fixed?
I am running a Mac and small Cintiq with an on-screen keyboard (so typing speed is slow and screen area at a premium), and the button on the pen (set to be an 'option' key) sticks on occasion.
What's happened to the key command for viewing at 100%? It has always been Option/Command/0 and that doesn't work any more with this latest update. The Menu symbol is now a lower case n (which doesn't work) and the only way to view at 100% is to go through the menu. It's slowing me up badly when editing?
I have a problem whereby my brush does not deliver the full color opacity even at 100%. It only delivers up to 50% (sort of). But I had to stroke twice to get the color that I want. This happens when Transfer option with Opacity Jitter is set to Pen Pressure. Why is this so?
However, Flow Jitter does not seem to have a problem with delivering the full color under Pen Pressure. I'm using a Wacom Intuous 4 Medium tablet.
I want to create a top down view image of a pile of autumn leaves. Something like the attached image.
So how to have an isolated image of a single leaf, create a brush from it, set the brush dynamics to create a random scatter and size of leaves and paint this on a few separate layers to create the impression the leaves are on top of each other.
The problem is since the singe leaf is color and not a simple 100% black silhouette, the resulting brush is transparent. So this is no good for what I need.
Is there a way to create a brush (or some other technique) so I can simply move the mouse across the screen and it will paste full color / 100% opaque copies of the isolated leaf with brush dynamics to create random sized / angled copies of the leaf?
Or is the only way to achieve what I need going to involve making manual copies of the leaf which would take a long time?
From what I can make of it, lossy is the option on GIF files, and therefore I am assuming that the optimisation is lossless for a JPEG at 100 percent quality and lossy when the quality is reduced?I just want to clarify that I am saving images for the web at the smallest size I can without losing too much quality.
All the images I save are 450px wide @ 75 dpi, but vary in length from 800px high to 1500px high, but have to be saved under 100kb. lossless and lossy in JPEG format in save for web?
I open a jpg image. It becomes "background" and locked in layers panel. I want to edit it so i click in layers panel, and get a box where I can call the layer a name and it changes from background to layer ( in my beginner´s terminology...)
When I click on "Ok" the image disappears, or really i think it becomes transparent, because in layer´s panel it is still visible. What has happened? I have done well all day, and suddenly this happens.
After playing with a new install of CS3, I see that there is banding in high value pixels. Yet when I open the same file in CS2, the photo is fine. I use a CRT. On my laptop, both versions work fine.
If I make a 16 bit untagged file with a black/white gradient, there are unacceptable bands throughout.
I've tried all of the options from the Color Management Policies: Preserve Embedded profiles; Convert to working RGB; and OFF. My working space is Adobe RGB.
I'm looking for a way to get a percent coverage figure for each C M Y and K so I can more closely determine print costs when printed to a CMYK printer where yeilds are given for 5% coverage. I'd like to find a way to take a corel document and determine that when printed this page is approximately 25% black coverage, 4% cyan coverage, 6% magenta coverage, and 2% yellow coverage for example.
I am running Xara Designer Pro X and there is a problem with my RGB-module.
The problem is that I need to have a color with the data R 241 G 145 B 27 (kind of orange).But, when I enter the data the color module converts it to percent (%) and the color is definitely not orange.
How do I make Xara RGB-color module understand that I don't want to use percent?
So the image in my window is not at a 100% and there is a whole lot of white space, it was fine till I added a new layer then it just downsized. Ive attached a photo of what it looks like.
I want my canvas size to be 36X24'' but the last bit is always just white space, which means my image is less than 36 inches long
I recently started noticing very bad gradient banding when using the gradient tool. It's specifically bad when using darker colors. I also noticed when using the blur filter I get banding with dark colors also. I am working on 16 bit document.

here is a screenshot of what I am seeing. My color mode is RGB Color 16 bit Color profile SRGB

airbrush banding, as well as gradient banding? I have my brush set to transfer, pen pressure and smoothing. It seems when I try to lay down a smooth gradient with the airbrush I get this banding effect. If I brush over the same stroke there's a dark spot that forms like a bullet eye that gets bigger and bigger. It's the same with gradients.
