With the magic wand tolerance set at 50% and global you are locking on to the color you are touching with it,, in all shades. In a 800x600 image there are less of these spots to lock on to than a 2000x2000 image. It doesn't have warp drive you know,lol.

An 800x600 image is just under half a million pixels. The magic wand takes about 5 seconds, which is not too bad. A 1024x1024 image is just over a million pixels. With double the pixels you might expect it to take about 10 seconds. It actually takes about 60 seconds. The 2048x2048 image is just over 4 million pixels, and I got bored waiting for it to finish.

The photo I found the problem was 20MP but not as bad for performance as the random noise. Selections with the magic wand were taking over a minute though, which is a right pain when you want to play with the tolerance to find a value that works.

p.s If anyone can recommend an automated tool as well that can cope with slightly distorted images such as this that would be a massive help too! slide1-1,5x,unquenched,control,well3,ol,300ms13841036 892 KB

With Photoshop 23.4 (June 2022) release, the Object Selection tool has been enhanced for making better hair selections in human portrait images. Object Selection tool can now recognize portraits and apply hair refinement to get a mask as good as that delivered by Select Subject.


After your selection is done using the Object Selection tool, you can further improve the mask results with the Refine Hair option in the Select And Mask workspace in the options bar for images other than human portraits like pets/animals/fur more naturally.


Beginning with Photoshop 21.2 (June 2020 release), Select Subject is now content-aware and applies new custom algorithms when it detects a person is in the image. When creating a selection of portrait images, treatment around the hair area has been vastly improved to create a detailed selection of hair. To temporarily turn off the content awareness, you can press and hold the Shift key while performing Select Subject. 


I have photoshop elements version 10. It has always worked fine. However, today I have noticed that the magic wand tool is not working. I have to cut out a lot of images from white backgrounds. Usually I use the magic wand tool, set the tolerance at 32 with anti-alias and contguous ticked. Once I have got rid of most of the background I then zoom in, change my tolerance and get rid of the rest. What is happening now is that I make the first click, zoom in, change the tolerance and make the second click. The cut out "marching ants" then disappear completely around the rest of the image and I'm just left with the second click I've made. Basically it is not remembering my first selection.

I don't know if this is anything to do with it, but I'm also getting a message up on opening the file (most of them are .tif files) that "this document uses an unsupported colour mode" and it asks me to convert it. It's giving me this message even with images I have previously downloaded and used without getting that error message.

Re "unsupported colour mode", I did check and it defaults to RGB colour mode for all images, so still not sure why I'm getting up the message about this, especially when it has never happened before. The only other thing I have changed is my browser - I got rid of chrome because it was causing me major issues and am now using firefox, but I cannot see how this could be causing this problem.

Cutting out details of an image can be very easy or a bit challenging. A lot depends on the background of your photo and how complex the image is. I'm going to show you the simple way using Pixlr Editor's magic wand tool. If you're not familiar with Pixlr Editor, it's a free online image editor. 


 The magic wand is magically effective when your background is simple in nature. If the background is one color or monotone or without a lot of complex shading or tones, or if the area you want to cut out has a strong outline that sets it apart from the background (e.g., a logo), you can simply use the magic wand and click on the area you want to copy or the area you want to cut. Once you do that, you'll see the respective area outlined with a flashing dotted line.


I'm trying to isolate the sky region from a series of grayscale images in OpenCV. All of the images are fairly similar: the top of the image is always a sky region, and is always a bright, gray-white colour. I've attempted contour-based approaches, and written my own algorithm to extract the line of the horizon and divide the image into two masks accordingly. However, I've noticed that the reliability of the magic wand tool in Photoshop on this image set is MUCH more accurate.

What is the best way to cut out the men from the image, similar to the "magic wand" tool in Photoshop? I imagine this algorithm won't have to be as sophisticated, since we know there are only two colors (black and white) and we want to extract the black images.

When I use the magic wand tool it also cuts out the bottle cap of the product because the bottle cap is white. To get around this I duplicated the layer, converted to smart object, made adjustments to the levels so that the bottle cap was no longer white and then used the magic wand tool. After I do this, I go back to the original layer, unlock it, hit delete and then delete the duplicate layer so that the background disappears.

The magic wand tool is by far the simplest way to do this. If the bottle cap is white but slightly different in color from the background (which it seems like it is, if you got it to work using levels), you can try changing the tolerance of the magic wand tool. The lower the tolerance, the more sensitive it is to subtle color changes.

i am using the magic wand but my image is more silver with some white shadow effects that the tool wants to delete. I have lowered the 'tolerance' to 0 and it still is wanted to delete unwanted areas. i have tried the lasso but that takes way to long to try and be precise. here is the attached image that i need the white background fully removed. any ideas how to do it without it taking pieces out of the top of the pistons (5 spots) that i dont want removed at all (white shadows) so to speak. the tolerance at 0 saves the one on the lower left side of piston 1.

The Magicwand tag makes it possible to click in a region of an image a user is doing segmentation

labeling on, drag the mouse to dynamically change flood filling tolerance, then release the mouse button

to get a new labeled area. It is particularly effective at segmentation labeling broad, diffuse, complex

edged objects, such as clouds, cloud shadows, snow, etc. in earth observation applications or organic

shapes in biomedical applications.

The Magic Wand requires pixel-level access to images that are being labelled in order to do its

thresholding and flood filling. If you are hosting your images to label on a third-party domain,

you will need to enable CORS headers for the Magic Wand to work with cross domain HTTP GET

requests in order for the Magic Wand to be able to threshold the actual image pixel data. See the

Label Studio storage guide for more

details on configuring CORS.

The Magicwand tag is configured to work with an Image tag that it will operate on for labeling.

If you are storing an image cross-domain that the Image tag will reference, you will have to

correctly setup the crossOrigin on the Image attribute. This attribute mimics the same

crossOrigin attribute that a normal DOM img tag would

have ([reference])( -US/docs/Web/API/HTMLImageElement/crossOrigin).

- If you create a new document from clipboard. Flood select tool (Magic wand) will never work. Select color range won't work either. However, if you export the image to, say TIFF format, then open it, then somehow magic wand will work. If you are reading this I encourage you to try it and see for yourself. Just hit print screen button to capture your display screen. Fire up Affinity Photo and create new doc from clipboard. See if you can select anything using magic wand.

I am often working off screen shots of our existing products. I would like to use magic wand to change the color of particular elements of the UI. I would also like to be able to select a UI item from the screen shot and cut and paste in in order to move it.

Thank you for your message. It sounds like you are looking to use the magic wand tool and chroma key in order to select pixels in a flat image, with the goal of removing or recoloring the background, as well as splitting elements into layers.

For your specific needs, the magic wand tool would be useful for selecting individual elements of the UI, allowing you to change their color or move them to another location in the image. Additionally, the chroma key feature can help [remove the background from an image]( -to-create-transparent-images.htm), leaving only the desired UI elements intact. 006ab0faaa
