You may need to do this again if you are very particular and if some background still shows. If one now clicks on the check mark, the software will do another perspective crop, and the remaining photo should only contain the painting you want. The resulting dashed line should be the perfect match between the outer edge of the painting itself and the rest of the background. This shape will not be a perfect rectangle. One can now do another perspective crop by placing the cursor at one corner of the painting and carefully run a dashed line along the border of the painting and the remaining corners of the painting. The software will put the resulting photo into a rectangle. Be sure the “perspective box” is checked and click on the check mark to do a perspective crop that will remove most of the background. In Adobe PhotoShop, on the home page, one can open the original photograph and surround the painting with a relaxed dashed line on the photograph which will not touch the painting (and will not be a rectangle!). Open your image, choose the Crop tool, then click and drag over the section of your image that you want to keep. For example, if you have a picture of you and your family, you can crop the image to remove all the tourists standing next to you. When you crop an image, you cut a portion of an image from a larger image. All the paintings I photo are rectangular originally, so the final image of the painting should be also. This wikiHow teaches you how to crop your image with Gimp. We’ve covered lots of ways to remove the background from images, but given the right situation, the easiest way will be using fill tools like the Bucket Fill, Magic Wand, or Magic Eraser. The resulting photo always has a background that must be removed, and the image of the painting itself should be the complete painting. They can be easy fixes, and here’s three great (GIMP friendly) tips to help in three different scenarios. If you want to closely examine any one of the GIF frames, you can disable the animation and specify the frame number you're interested in.I photograph artists’ paintings. In the options, you can also find a section about GIF frame delays, frame sizes, and frame counts. The "Animation Preview" option lets you see the input GIF with the original background and the output GIF with the removed background. This option works only in the browser and illuminates the removal areas using black and white pixels. To see exactly which pixels will be removed and which will remain, you can use the "Alpha Channel Preview" option. It is also useful if you need a specific image size that does not match. If you want a true circle, use the Fixed. ![]() Create a circular selection with the Ellipse select tool (the 2nd one in the toolbox). Learn how to erase the background of an image, including portrait images and photos with any type of hair, using this simple workflow I created using GIMP 2. First, make sure that your layer has an alpha channel. ![]() This tool is often used to remove borders, or to eliminate unwanted areas to provide you with a more focused working area. But there can be images where corners are transparent, so that only a circle shows. It works on all the layers of the image, visible and invisible. ![]() For example, the percentage 0% means match just one color and 20% means match 20% of similar color tonality. The Crop Tool is used to crop or clip an image. In this option, you can specify the percentage from 0% to 100%. If the background of your animation has various shades of the same color, you can remove them as well via the shade matching option. Similarly, if you enter a mathematical color value "#0000ff", the program will remove all blue pixels. For example, if you enter the color "yellow", the program will remove the yellow background from the animation. The area that will be removed from the GIF is selected by matching the specified color in pixels of the frames. When the background is deleted, you can download the transparent GIF right away. ![]() If your GIF has a single frame (it's static), then it deletes the background from just this one frame. If your GIF is multi-frame (it's animated), then it loops over all frames and deletes the background from every frame. This is a browser-based program that deletes the background color from all GIF frames.
