Photoshop :: Threshold Leaves Grey Pixels Behind
Mar 31, 2013
I am using the threshold tool to create a stencil. I first used the Quick Selection tool to cut out the objects I wanted and then tried to use the Threshold tool to create a black and White Only image.
However, for some reason, especially on the edges of the objects, the threshold tool left some grey marks, instead of black and white.
I tried using the threshold tool again, but not all of the grey marks were removed

I am making a logo in paint.net and I have text and some lines drawn, when i use the eraser it deletes and shows the grey checkered squares BUT when I save it there is light grey for where the eraser has been 'erasing'
I have white for primary and secondary and opacity on full.

I had a .JPEG of a leaf photographed against a white background. When I went to turn that white background into a transparent alpha channel, it seemed to work okay....except for the fact that when I then went to select the new alpha channel via the Fuzzy Select Tool, it wasn't selecting all these newly transparent pixels.

Whenever I try to use the 'Colour to Alpha' tool, while it works on most of the image, I always get little white dots left behind, and have to spend ages use the eraser tool to get rid of them.

as a user of pse 6 I 'm used to work with darkgrey background in the organizer.
This works perfectly for quickly assessing brightness and contrast of pictures.
In pse 10 however I could not find any button to change the preset lightgrey background colour to darkgrey.

I have been using too much threshold, black and white simple stuff. I was wondering if there was anything similar to it but different style?

If I am constantly making frames in photoshop for use in the video world (ie. They will be on TV) the pixels need to be rectangular (or 4x3) in aspect and not square.
I know in programs like After Effects and Combustion you can set when saving an image whether or not it is square or rectangular pixels.
How do I do this in Photoshop if it can be done?

I am currently running Map 3D 2012 with CadWorx and I am having an issue with one of my multi tab drawings. Any object set to plot grey (any grey), that is in paper space, is plotting black only in one of my layouts. similar objects in model space and in both spaces on other layouts are all plotting accordingly.

I want to use the Threshold Alpha command on a Layer of Solid Noise, but nothing happens. If I set the threshold to 255 everything goes transparent, anything below that the clouds are supremely unimpressed. It's an RGB image, has an alpha channel, no Alpha channel lock, the Threshold tool works fine. I also tried creating another test picture with several gradient in greys and colors, and they are equally unaffected by Threshold Alpha.
I'm using GIMP 2.6.11 on WinXP SP3.

2 days on GIMP. I need to adjust the clone tool so it's 1080 pixels vertical and about 20 pixels wide. I googled and searched, but I can't seem to find the right phrasing.

I have several layers in an image, and I need to align them precisely. The ordinary layer shift ("move pixels") by multiples of pixels is not sufficient. Is there a tool or plugin for PDN that allows sub-pixel shifts (i.e. moves by fractions of pixel)? And rotations by very small angles?

i tried restarting gimp but it did not fix my problem. All of a sudden, out of nowhere, my fuzzy select tool selects WAY too much even at a threshold of 1. at 2 it just selects the whole picture.Re-installing did not fix.
i am creating black/white based icons. So it is a 48x48 image. i am mainly trying to fuzzy select black, white, and transparent selections. As you can guess, it has become impossible now and i don't know what i did.
EDIT: Okay so it actually isn't selecting "too much" per-say. i willt ry and explain the best i can here:
Black and white image with the exception of some shades inbetween.Select fuzzy select and put threshhold at 1. Click. Selects all the white (i actually think it misses some). i hit SHIFT and click on a pixel that is slightly not white. VERY SLIGHTLY. In fact, it may actually be white. It fuzzy selects EVERYTHING.
Another example on an image that is Black and Transparent (with shades inbetween) Slect black on threshold 1. It selects All the black AND all the shades inbetween. Eveything except flat out transparent. i hit CTRL and select a shad einbetween and it deselects everything.
EDIT 2: Doesnt matter the threshold apparently. It will do this on any.
EDIT 3: The solution, after all, was so save these problematic images as JPG and then open them as the JPG.

I would like to obtain a black and white image of a photograph of a book page.
My attempt to do this is by running the threshold function over theentire image. This appears to give the desired result, but onlylocally. It appears that the optimum parameters of the thresholdfunction vary by position (i.e., according to some scalar field), withone extreme in the center of the glare and then radiating outward. Sojust running the threshold function over the entire image withconstant parameters always gives sub-optimum contrast for 75% of theimage. Will I have to find a way to run the threshold function withnon-constant parameters, or is there some other tool to do the job?

I scanned some images to Tiff format and when I bring them into Gimp I can't seem to get the threshold effect to work. The other color effects work but not threshhold. I check with other Tiff images I have and they work but not for this new set (done on a different scanner).

How do i select the white sky in this photo without selecting any of the tree or leaves? I know it can be done with the "selecting tool" but it takes forever to do every little but of sky.
There has to be an easier way?
If it helps I have photoshop 7.0 & CS3.
I would like to use a brush tool and put some blue sky between it...

While trying to use cloning tool, it would leave a trail of white & would not clone the designated area! If I buy the full version, I don't want my money waisted on a program that doesn't work properly!

Is there some good way to do this when there are subjects that have many small features, sure as leaves or bird feathers? I have tried different selection methods and feathering, but always wind up with halos or sudden changes at the boundary, that necessite huge amount of detail work to get rid of,

When I specify where the replacement content should come from it looks right as I am selecting it but when I let go of the mouse it makes a reflection of the nearby objects.

I've made a fairly extended action that consists of several groups/folders. Unfortunately, the action leaves one group in particular open, and I would prefer it closed.
I woud simply extend the action by one step, that of closing the group; but clicking the open/close triangle seems not to be a recordable step.Nor can I find a menu option.How can I record the closing of a group?

I did a great image last night of friends all merged together.
when i turn the opacity to say 40% with a layer mask on each image, it still gives a pretty distinct edge to the pictures and doesnt blend together.
