Magic Wand Selection Tool Fails to Operate on Precise Pixel Color
I had an interesting thing happen with Photoshop CS5... My Magic Wand tool got to where it wasn't selecting pixel colors based on the one under the tip of the tool when clicked. It was selecting what seemed like similar colors, but its operation wasn't really predictable.
It turns out that in a prior unrelated operation (days ago) I had changed the color picker to look at a very large number of pixels when sampling.
Having chosen the above, the setting was sticky and modal (meaning it subsequently affected samples taken from then on by a variety of tools).
I didn't think that this should affect subsequent samples taken with the Magic Wand tool. I'm not sure this has always been the case, but it doesn't seem as though it should work this way.
Notably I don't see any way, while the Magic Wand tool is active, that the above sample size can be changed. Nor did Resetting the Magic Wand tool correct the situation.
Should the previously selected color picker sample size actually affect the Magic Wand tool, or is this a case where someone at Adobe consolidated the pixel sampling logic a bit too aggressively?
If the latter, here's an adage to post in the halls of Adobe Engineering: "Make everything as simple as possible, but no simpler."

Hm, appears to be an old issue: http://forums.adobe.com/message/3226358
What I can't fathom is that it's never bitten me before. I do tend to leave the eyedropper on 1 x 1 pixels, but I occasionally do sample larger regions.

Magic wand selection tool misbehaving
Help.. I've been having this problem almost everytime I use Photoshop CS5 and previously with CS4. (never a problem with CS or CS2). When trying to make selections based on color or contrast with the "magic wand" tool, I find it develops totally erratic behavior. Even setting a tolerance of 1 or 3 (feather = 0), for instance, might select large areas or completely different tonality.
I end up making my masks (selections) either manually or by using a combination of tools like the magnetic lasso. This is causing me to waste a lot of time. If anyone has a clue, please let me know.
My system is an otherwise robust 64bit WIn-7, Xeon CPU, 18GB Ram.
Thanks in advance,
Doug AC.P.
Thanks for your response. This is just a single layer (16bit). The tool option bar is adjacent to selection areas in question to the left. Am I missing something here? To add or select areas, I usually use the shift or alt key.
Thans,

Magic Quick Selection Tool NOT working right. Help please?
We've used the magic quick selection tool lots and most of the time it works well.
It's very slow.............. v e r y slow and I'm wondering if there's a patch to download from Adobe or
what to do to fix this. We have pictures to edit and it's making the editing torture. Please help?
Thank you so much. tkccvalentineIt's the Quick Selection Tool in Photoshop Elements 9 and I'm trying to get the background and make it another layer so I can even out the color of the background then bring down the transparency. Not sure if that makes sense. I'm new to this.... Sometimes the area it will grab can go ...not fast.. but not slow. Sometimes it's like it's just messed up and literally takes 30 seconds to process each move. I rebooted my computer and re opened it and it helped a little. It's not clear what causes it when it messes up and when it doesn't. Just frustrating. It's probably user error because I'm so new at Photoshop. Thanks for your input. I really appreciate it.

Acrobat X selection tool fails to detect paragraphs of text...
Acrobat X selection tool fails to detect paragraphs of text. Manually selected paragraphs have broken sentences with line breaks. This problem is also noticed when you attempt to triple click a paragraph and only one line of text is selected instead of a paragraph. Can this be fixed?
can't it tell by the visual formatting of indents, text proximity/clusters, etc? if humans can tell, why can't acrobat be trained to tell?

In PS i can Magic wand selection shape from one layer, drop to sub layer and copy that selected shape from that sub layer. How do I do this in illistrator, and moreover, from multiple layer at the same time.
For instance, in PS = Import an image of gold - select a text phrse with wand - drop to gold - copy paste = gold text.
How is this done in illustrator?Illustrator C6
Basicly I want to do what takes me 10 minutes to do in PS in Illistrator. LOL! I realize I must learn Illistrator; especially for logo design.
I want to select my objects in Illistrator and drop to another layer and copy that layer but with only the selection to create another new layer with that which I
originally selected and then copied from another layer.
1. Select objects
2. copy that selection from another image. "gold effect taken from an image"
3 paste that which was selected = that which was selected, but in gold. -
Clipping paths from magic wand selection
I've been looking through dozens of tutorials but even the one's that mention this they all assume you know how to do it. All I would like to do is turn a selection made using either the magic wand tool or the other selection tools/methods and turn that into a clipping path.
This is the selection i've made with the magic wand tool:
http://img414.imageshack.us/img414/9307/screen28qd.jpg
Also is their any way to turn a whole layers contents into clipping paths? For example I have that image on it's own layer with no background, could I turn everything on that layer into a clipping path?
Clipping paths for this kind of thing as far as i'm aware is the only way to import images into quarkxpress with no backgrounds.
thanks
samHey Sam, if I'm not mistaken you simply have to make your selection, then select make "work path" from the Path window, next you save the path and then select "clipping path" from the Path window and select the saved path's name.
I would think this would work with layer selections as well.
Hope this helps...

Magic wand selects everything. Help!
Hi,
I'm using Illustrator CS6 and I haven't been able to use the magic wand tool. I have Photoshop CS6 and the magic wand works perfectly in that program. The problem is that I mainly use Illustrator to work and if I try to open the image in Photoshop the colours don't fill properly (white fuzzy edges) so it's not really a solution for me to just use photoshop instead. I'd really like to get to the bottom of this. I've looked through dozens of forums and tutorials and can't find anything that solves my problem.
The images I'm working with were created by myself from scratch using illustrator. I was working on a multilayer image, and I selected the option to use all layers in the magic wand tool option bar but it didn't work. So, I flattened all layers so that I would be working on a single layer image and still nothiing. The image has been fully coloured using live paint. I want to be able to quickly change the colours in the image without having to reselect and colour every portion. I worked with a limited colour palette of maybe 10 colours, so really this image should be perfect for magic wand. I have set the tolerance at zero for fill colour. The other options are deselected. If someone could help it would be much appreciated. It's very frustrating!!
Thanks!
ShiraThe magic wand does not select objects it selects the color. That color is placed in the swatch well at the bottom of the toolbar.
What you can do it use the selection tool (the back arrow at top of toolbar or the lowercase v on keyboard.) Select one of the colors you want to change, then in the top menu goto Select>Same>(choose an option) This will allow you to select all the same colored fills or strokes and change that color all at the same time. Just a matter of double clicking on that color swatch at the bottom of the toolbar to bring up the color picker or use the swatches in the top tool bar when the selection tool is active. -
Magic Wand selects the whole picture
Hey, i tried using the Magic Wand Tool to select an area before and it works. But yesterday idk what happened and whenever i used magic want tool to select a specific area it keeps selecting the whole picture. How do i get this fixed? Please reply asap. Thanks!
Hi SepetMTJ22,
I would try looking at Charles' suggestions. It is most likely that you have an empty or solid layer selected, which would select everything for you:
Or that you have a sample size that is too large, make sure you have it set to a small enough point sample. One is recommended. -
Hey guys/gals,
I have photos of a few models (not super models, lol) photographed in front of a chroma color green matt. When I used the magic wand to select the green matt for deletion it selects some of the model. The model is a stark contrast in color (purple) to the green matt. There doesn't appear to be any green reflection on the model. It was shot in a light tent/cube to prevent this. Is there anything I can do short of manually deleting the green material? If I have to I'll manually cut out the image one pixel at a time, but I prefer a quicker solution.

I do illustrative site plans for an architecture firm. I frequently use the magic wand to create selections in pdf's created from a CAD system. I usually import them as a smart object so that they may be updated regularly as design changes are made. However, in CS4, I am finding it very difficult for the magic wand to make selections in between lines of a pdf. No matter what I set the tolerance at, it seems to select more than the area that I am trying to select. I recently installed all updates and it worked for one day and then returned to making incorrect selections. I need some help or advice.
Thanks,
Caleb SchultzAfter I posted this I figured out the problem, and it is just as Josh suggests. Apparently, the magic wand and eye dropper are directly linked to the sample size of the eye dropper. Thanks for your help and suggestions.

Contiguous magic wand selections
This feature would be fantastic. I want a multi-option contiguous feature for wanding. Hotkeys could govern which selection is made.
1. same group contiguous
2. same layer contiguous
3. entire image contiguous
(e.g. overlapping or touching precisely in 2D space)
AND
Another "same color values" hotkey that can combine with the previous 3.
AND
Just to challenge the programmers... if the user preselects multiple groups, then uses the special magic wand, the selection spans just those groups.
wouldn't that be grand?
dIt looks like if I did this I would have to have an F key to tuen it on and then another f key to turn it off.
Scripting is best I think as I would be able to assign any key as opposed to F keys
Thanks just posted on PS-scripts in the hope I get an answer too

Quick selection tool failing to select objects
Every time I use Quick selection tool it selects the area which I don't want to use. I have a website called JoGuru Social Travel Network for which I need to edit it's logo. Now since the logo has many green and blue variation I can't select the area I need.
I thought of changing the color of logo so that it looks refined but green color signifies travel and i can't think of using any other color. It would have been easy to pick other color. For me Green is God. I must use that only. I also need to encorporate small road in it that defines journey to infinity. This tool use to work well before. It's giving me problem for the first time. Please help.I have managed to do this... Snap to grid helped a lot ! Thank you.. I will now start learning all these things one by and and slowly slowly. Thank you so much Trevor !!!

Magic wand selection to outlined border

Hi Everybody,
I need an iPad app that can open an image and has a Magic Wand-type tool so I can select white background around a subject. Then delete the white areas so it becomes transparent. Then save as a PNG with transparency. I've tried Pixelmator...I can select the white but I can not delete the white. I downloaded Photoshop Express...no magic wand tool.
Does anyone have any recommendations?
Thanks,
GaryIt's a shame you don't have Mac. The feature is built in the system (in Preview, Pages, etc).
That makes me think: this feature should be in the iPad iWork apps too (Pages and keynote): check out this guide: http://www.cultofmac.com/256475/knock-out-those-backgrounds-instant-alpha-hidden -in-pages-for-ipad-ios-tips/
