![]() ![]() Important to choose the tool best suited to selecting what you want from an image. ![]() Fuzziness is luminance levels, can increase. ![]() Make sure the channel you want to work in is selected.Ĭolor range: Dialog box-selection should be white, use eyedropper to pick color range. If there are areas you need to correct, you can erase or fill them in in the alpha channel using the brush or eraser tools. Choppy edges solved by auto enhance button. Size the brush to get into the regions you want. Paint away selections or do it with option key. Brush in a selection, to what is considered an edge. ![]() Quick Selection Tool: “ w” below the lasso tool, paired with magic wand. If you know you have a completely blank background, you can just select that. Turn on rubylith in alpha channel to overlay and compare it to original. Can smooth it- go to Select/modify/smooth. The menu selection saves it as a negative (black) area Why? The channel icon saves the selected area as a positive (white) area. Alpha channels are transparency information that you can use to separate out parts of an image. This saves your selection on a new channel, an alpha channel. Don’t try to select an entire image all at once. Looking for edges-rapid luminance changes. Press delete key to get rid of bad points. Click on initial point, move cursor along edges and line is automatically drawn. Magnetic Lasso tool: Most refined, and automatic, good for irregular edges. Hover over first point you clicked, notice o, or just double click. More refined, good for objects with straight lines. Simple lasso is good for selecting large areas without worrying about details of edges. Use spacebar to move around inside the image. Option click over the marquee tool to toggle between flavors of the tool. Select horizontal tool and click-gives you selected row. Single pixel tools we’re ignoring for now. Note options for feathering, fixing aspect ratio and selecting fixed size.Įllipse tool: same keys as above. Release space bar but continue dragging to complete marquee. Move the selection by pressing and holding the space bar before you finish dragging. Press and hold shift/option keys as dragging in order to draw from center out. Add to selection or subtract with shift or option keys. To move selected pixels, go back to the move tool ( v). Can move inside the selection line still in this tool. Marquee tools-rectangles and ellipses (“ m” key) unconstrained shape, shift plus tool makes a square. In Layers, choose duplicate copy, and okay. The first thing you should always do when working in a file is duplicate the original and turn it off, so if you make a huge error, you can get back to where you started. Selection tools, creating layers for puppet limbs: (use Melda) See “Photoshop Masking & Compositing: Fundamentals-#4 the essentials of selecting” Include resolution, 24 bit color, Descreening. Set up a station to demonstrate scanning. We cannot easily and cleanly increase the resolution, we have to scan at a higher resolution in order to have a high quality image. If you know that the pixel dimensions of your frame are 1920 x 1080, then you know the percentage of that space that this image will take up. AE will ignore “Document size” and read this as 72 ppi. Show example of what happens when you zoom in too far. Scan your image so that you have high enough resolution to zoom in as far as you will need to and go no lower than 72ppi. Resolution: Inside After Effects and Photoshop, the pixel is the unit of measure. Can get rid of background with key effects, but is probably better to do this prep beforehand so rendering and animating takes less time. As flat image, notice that we have to do some work to delete her background and separate out limbs. Lecture/Demo: Photoshop tools for preparing art for After Effects Part two is hands on exercises exploring some handy After effects tricks and features. This outline is divided into three parts: part one is a lecture demo of Photoshop tools that you can use to prepare artwork for After Effects.
