Photoshop :: Remove Single Pixles?
Feb 19, 2004
I have a large image that has been scanned in as just pure black and white. Unfortunately there seems to be a lot of noise in the form of single black pixels all over the image.
Apart from manually erasing all of the pixels (the image is huge!), how else could I do this. Is there a way to automatically select any single pixels within an image so that I could just delete all of them at once, or perhaps if I blurred the image sufficiently so that they disappeared and then sharpen the image?

In Elements 12 is it possible to print a single item without having to go through add/remove items process? It seems to be set to print everything I have open as a default.

Working in AutoCAD™ 2012... Is there a way to "erase" an entity, line, etc. by selecting it and having it immediately disappear? I work in 3D/DXB files a lot and it really useful when working with an audience either for on-screen seminars or over-the-shoulder.

I have pictures that have different objects over a canvas like/un uniform back ground.
I need to remove that background without any part of the objects them self.
I mange to get most of the background out using the magic wand , but i'm left with many random single/groups of noise pixels left in the picture since they were not captured with the magic wand.
most of the time i can remove those using the eraser or use the selection tools with different shapes around the pixels and press delete.
but those methods take lots of time, specially around a complex objects and as i'm getting near to them, i need to make my selections/eraser radius smaller and smaller.
I have tried to use a plugin called "Reduce Noise" that i found , but it does not work.
faster way how to remove this noise pixels without any part of the objects?
a plugin that "scans" the image/selected area and remove all pixels that are surrounded by transparency in it?
p.s I can't always select only the object/s itself/them self and just move it/them to a new picture.
p.s.2 maybe a plugin that the user can choose up to what size, a group of pixels, should be removed ?

I would like to know how to change the colour of a single layered, single coloured gradient (foreground to transparent) image. There is nothing more to it than that other than I don't want to use the hue/saturation adjustment as it's hard to get a specific colour.

I'm trying to run a simple batch command that works fine in an old CS2 I happen to have but in CS4 every action I create and every stock one from the list returns the message "could not complete the batch command because the disk is not available". Not even actions that don't require saving to a disk work.

I have a very placement sensitive project . though i am going forward with the project i find myself having to lock and unlock many layers in a 44 layer project.
I am have been making mostly color and effects changes to create the style. So i was wondering if there was a way to lock the position and still edit the effects mentioned?

I've got an RGB image, but each pixel actually has identical R, G, and B values-- the image is just varying degrees of grey. (It's not actually a greyscale image, long story. :P)
If I click on the single channel view, it's much brighter than the RGB combined view. Each channel appears identical to each other channel, but they're all considerably brigher than the combined RGB image.
Do you know what adjustment is being performed?
(That's the short question; elaboration follows.)
Photoshop is aware of this adjustment, and will replicate it if you copy the RGB image and paste it into a single channel of a new image. For example, I can copy the entire image, create a new image, and then paste into just the red channel of the image. Visually, the combined RGB view of the source image and the single channel view of the dest image will look identical.
How was this achieved? Photoshop darkened all of the values: a pixel that was 24, 24, 24 in the source image is now 7 in the new red channel.
I haven't been able to replicate the conversion. Visually, it looks a lot like a gamma adjustment, and values in the middle range roughly approximate an adjustment using a gamma of 1.266 (which seems odd, so is likely not what's occurring). Values in the lower range, however, are darkened further-- a gamma adjustment of 1.266 will leave them too bright.

It was the "Creating Classy Glass Buttons" one. One of the steps says to flip the layer vertically. I can't quite figure out how to do that. It always wants to flip the whole thing.
I'm using PS7.

I have created two Raw files with one focuses on highlight while the other on shadow. Within Photoshop with these two files open my intention is to use the Move tool and drag-and-drop one image over the other as a layer. At the present I am having trouble to get these two images to register as two layers.

In building a composite, I dragged one image into another image. Of couse, this created a separate layer in the receiving image. Since I then discovered that the color saturation needed to be lowered ONLY ON THE "DRAGGED IN IMAGE," I then clicked on Hue/Sat and began the desturation process. But even though I had selected the "Dragged In" layer, all of the lower layers were also desaturated. So my question is: Is there a way to use Hue/Sat on a single, selected layer? How can I keep the other layers from being affected by the hue/sat operation. Of course, I could have done the desaturation before I dragged it into the other image, but it was only after dragging it in that i could really match the colors properly.

I need to convert a layer so that it is only one color(black). It can't have any other shades in it. I tried color overlay, but there are still little spots where there are shades of grey on the outsides of the graphic,

i've never been big on styles, so i've never really come across this before, but how do you export a single style instead of a style library? and if you can't do that, then how do i create a new library?
all i want in the world right now is to send a single style to the guy across the office to the other graphisist here, rather than go through the process of telling him each setting one by one...

I'm on a Mac with Photoshop CS. I have this tapered swoosh, so to speak, with a layer mask attached to it. When I go to Edit/Free Transform/Distort, I only get a single box when, as far as I know, I should be getting multiple. This singular transform box only gives me as much movement as the regular transform, which isn't enough. Does anyone know what's wrong? It's necessary that I dip the middle of the swoosh and modify the swoosh in ways that only a whole bunch of directional options will handle. Should I be using Warp? I don't have Warp though...

I have created a brush that is meant to mimic stitching and i would like to be able to rotate one "stitch" or stroke at a time... ( i pasteurized the shape)
I have used Ctrl + Click on the Shapes Thumbnail to make a Selection and then went to Select > Modify > Contract and then I went to the Paths palette and from the drop down/fly out menu i chose Make Work Path and then. I Right Clicked on the Work Paths Thumbnail and chose: Stroke Path > Brush (chose my custom brush)
I manipulated the Path as much as possible to create the curves as needed but. I still need to modify the stitches . If i recall correctly i think i read somewhere that i can use a Marquee tool select individual brush strokes (that are a part of the same path) to rotate and/or relocate/move in general, however, i cannot seem to get it to work for me ... so, i am thinking i've forgotten a step or that i may be totally wrong.
Can i rotate a single brush stroke? is there a way to "ungroup" like in Illustrator or some other sort of Ps creature.
Above is an example of what i'm trying to explain ... all the dashes are on one path but i would like to be able to rotate just one at a time (like in the red circle). is this at all possible? i've tried to paint em all manually but it just doesn't end up looking nice at all.

I'm trying to erase all of a single colour from an image. I use the colour range select to choose the colour (orange) however when I erase, it seems to erase an underlay underneath colours (esp yellow) in unselected areas.
How can I stop this?

If I have two vector shapes on top of one another, when I drag over both to select a few nodes from the top one, it selects both (this is now a 'feature'). I don't want this.
I know if I want to select only the top one now that I have to isolate the shape first, but this is terribly inneficient for the way I've been editing vector shapes for years now.
Is there any way to turn off multiple layer path selection and having to isolate anything? While the new feature can be nice at times, it's mostly more of a hinderence than a way out.

In previous versions of Photoshop it was default behaviour to affect the shape in the currently selected layer when using the Direct Select tool. In Photoshop CC it's default behaviour to affect all shapes (in seperate layers) within the selected area. I often want to change some anchor points on a single rounded rectangle, for example, to make it fit perfectly.
Is there any way, without selecting "isolate layers", to restrict the selection to the currently selected shape layer?

I'm playing around with images of projector screen fabrics and want a single number that indicates how close to being neutral the image is. What I do is select a small portion of the image, average the selection, and use Photoshop to tell me the color numbers. Let's just say the Lab numbers (L, a, b) for three fabrics are:
A: 80, -2, -6
B: 85, 7, -1
C: 83, -4, -4
The L gives me the luminance (how bright the screen is), and I think the "a" and "b" should be zero for a true neutral. But if they are not zero, what is the best way to indicate how far the color is from gray?
Use an absolute average? In which case the single number, call it "grayness" (with 0 being true gray), would be 4 for all samples, indicating that the fabrics are equally gray.Use Pythagoras to calculate the distance from the a,b origin (assuming "a" and "b" can be treated as perpendicular axces)? In which case the "grayness" value would be: A = 6.3, B = 7.1, C = 5.7, indicating that C was the closest to gray.Other method.

I design wedding albums in a third party software which then exports each page spread as a layered PSD. I then like to go in and "polish" each page spread by adding vignettes or other enhancements to each image. Some very simple actions I have no problem with getting to work, however, I can't figure out how to make an action that will run on just the image I have selected and add a vignette to just that image regardless of the image size and shape. I have an action that will do this on a single non layered image but it won't work if the image is in a layered PSD because it tries to add a vignette to the entire document and of course runs into problems. Can anyone help me with creating an action that would add a vignette to a single image in a layered document?

We produce a number of A5 publications and the need has arisen for me to produce each page of each publication as a jpeg (can't be anything else) for web publication.
As I see it my current options are:
1. During the PDF'ing process from InDesign we produce an individual PDF per page (usually 40 pages per publication and 4 publications) and then batch convert them in PS.
2. We create jpegs from a 40 page PDF, one at a time.
Both are rediculously tedious and time consuming, and we would have to pass this cost onto the customer which I am loathe to do.
I am therefore wandering whether there is a way in PS to set up a batch process where it will open the pdf 40 times, incrementing by 1 page each time and saving that page as a jpeg.
Alternatively, there may be away that I can produce 40 individual PDF's in one process using Acrobat Pro/InDesign, and then do the batch process in PS.
Both my printer and his own designers and myself have drawn a blank really,

It's a single layer, the image is 32 x 346 pixels and I'd like to know how to blend the bottom quarter or so of the multicolor sidebar to the default black.
