Basically it blocks 50% of what is left behind, as opposed to being a pure 50% opacity in a additive way. Therefore working in an inverse exponential way towards 99.999...% opacity. So laid on top of each other: 1st stroke: 50% 2nd stroke: 75% (50% + 50% of 50%) 3rd stroke: 87.5% (75% + 50% of 25%) 4th stroke: 93.75% (87.5 + 50% of 12.5%) 5th stroke: 96....

Yes, simply use "Nearest neighbour" as the resample algorithm in the "image size" dialog (image -> image size) Edit: @CAI gives a nice tip - "It's also worth mentioning, if you don't want any distortion at all, multiply the scale by whole multipliers (so 2x, 3x, 4x or 200%, 300%, 400% etc.)"

Color number is just half the game. The other is to compress the picture after color reduction. This lossless compression, searches for repeated patterns in scanline order. Long story, in short: When you add the logo you are increasing the image variability, entropy. Compression gets worse the more entropy there is in the image, as the computer can nolonger ...

An easier way than masks: using blends. Here's how I would go about creating the first one: Grab yourself a picture of a cityscape. Make it greyscale if it isn't already. Next, grab yourself a picture of a bearded hipster with glasses. Convert to black and white or greyscale and up the brightness and contrast. I've also painted some white over some ...

Each stroke is moving 50% from the current color towards the brush color. The formula would be 100% * (1 - (brush opacity ^ number of strokes)). So going from white to black, you will have: 50% gray 75% gray 87,5% gray 93,75% gray 96,875% gray 98,4375% gray ...etc, slowly moving towards black. I.e, you'll never actually truly reach full opacity, but at ...

Although joojaa is mostly correct, actually GIFs do not use Run Length Encoding. They use the LZW algorithm. Basically, this algorithm can take advantage of EXACT repetitions of horizontal strips of pixels. This works very well for solid colours and regular dithering patterns (e.g. checkerboard patterns). However LZW can only "remember" 4096 different ...

Icons are made to not include text within it for many reasons. First, Icons could be smaller and any text in it could be hard to read Second, Icons are made to relate and connect a certain function with well know visual representation to man mind, without thinking or even reading. Third, what would you do when somebody in other country wants to localize ...

Start with a very loose idea: Marquee tool to quickly go over the High: Add your high color: If I press Cmd/Ctrl+Plataeu thumbnail on Layer Panel it will select it for me. Then do Select → Modify → Expand. I used 15 pixels. Notice the bottom of the Plateau and the Selection now have an offset to it: Create a layer beneath, color it, ...

There are many reasons why you would want to rasterize text. I agree that in general one does not want to do it if it can be avoided. Reasons for rasterization: You dont trust the end users application to do it correctly or you are having some issues with your own/a known rasterization engine. In these cases you can gain benefits. This can be a valid ...

There is no way to print RGB colors in CYMK simply because you can't 'print' RGB, as it's a projected light color space, not a reflective light (ie, ink) color space. Many colors overlap in RGB and CMYK spaces, but not all, as you've found out. You can use spot colors to print more colors that CMYK can provide--which can get you closer to what you might ...

Ok I am up to the challenge... First we need to re-frame the image. Now, What kind of floor do you need? For an Ultra Glossy Floor, just copy your door, Skew it, mask it and add a gradient opacity. The same for the frame of the door. For a Satin floor, apply a gaussian blur to this same object and use some mesh fill to add the spilled light. Play with ...

Advanced hair extraction tutorial First off, plugins and simpler methods are available. This is if you want to get higher quality results. It is largely the same as ACEkin's answer except going into details and with visuals. I'll be using this photo from Photo by Ariana Prestes on Unsplash.com: Note: I'm going to be doing the body in a separate layer so ...

It's been a while, but before it was possible to create gradients using exclusively CSS it was a handy tool to isolate a 1 px cross-section of a vertical or horizontal gradient to use as a background image. So if you had the following image as a mockup you could use the single-column marquee tool to grab a 1 x 64 px slice and save it as a lightweight GIF ...

I've designed billboard art (same basic size as your project) for several different vendors, and they mostly ask for 10th (1:10) scale artwork at 300ppi with some kind of pocket allowance. 100% scale is not generally necessary. All vendors are different and may have different requirements, though, so check their respective web sites for upload requirements.

Well, the upper part of the body (to be more specific, the torso) is not proportional to the rest of the body. That's what's beet bothering me a little about the image. Also, the arms appear to be a little small. image source The proportions used in figure drawing are: An average person, is generally 7-and-a-half heads tall (including the head). An ...

Take your image Pixelate your image. Work out the exact number of Rubiks cube cells you will have and make your image that size in pixels, so 1 cell = 1 pixel. If you don't know what scale you want to work at, don't know how many cubes you want to use etc. Using the Mosaic effect (Filter → Pixelate → Mosiac...) will help you preview quickly. Set ...

Options: Convert your art to CMYK and print it as-is. Convert your art to CMYK, and manually adjust the values to increase their vibrancy. (RGB to CMYK conversion can make things look muddy, especially those bright blues). If you're in photoshop, you can try a few different Adjustment Layers to get the colors closer to where you want it. Color Balance and ...

tl;dr: Type that isn't rasterised won't stay in shape on other machines. That's a bad thing for sharing and printing the .psd file. You may also want to use pixel editing on the letter shapes. If you don't share the .psd file and don't intend to use pixel-only effects on the letter shapes, there is no good reason to rasterise. As sharing a .psd and pixel-...

It largely depends on what your goal is. The "new and improved" method is okay for high end gif animations. If you're doing say an old school animated gif banner (sadly these do still exist) then I would just use Legacy. The new method would be to use Photoshop's Render Video functionality and then Adobe Media Encoder to convert it to an animated .gif which ...

If you want to keep the layer linked to your current document: Use Smart Objects. Right click your layer and click Convert to Smart Object. Double clicking the Smart Object layer will open the image in a new tab for you to edit and automatically update the layer in the original file. If you actually want to save it to a new document separate from the ...

I suspect this has to do with the limits of transparency layers. You say that it took 8 x 50% transparency to get 0% transparency. If you have 50% transparency, then 50% of the background colour should be visible through the top layer. If you apply 50% transparency again, then 50% of that NEW background layer should be visible = 50% x 50% = 25% original ...

It depends on what results you want. If you want it to look "blocky" (i.e. each pixel in the original becomes a square in the result) then MrMerrick's answer is correct. If you don't want it to look either blurry or blocky then you need a dedicated pixel art scaling algorithm. I'm not sure if such algorithsm are available for photoshop, I did find a plugin ...

Another possibility, here; try drawing your images using vector shapes. There is a little time investment, but the potential afterwards could pay dividends. Start by setting your grid size (say grid line every 10 pixels, with only 1 subdivision). Turn on grid snap. Using the pen tool draw your shape. For any parts of the shape that are separated (i.e. on a ...

These are definitely made by hand. These are so called "scientific illustrations" absolutely beautiful. Check your local library or internet for "botanical illustrations" I think it's not possible to fake this with photographs and filters. Or at least not with that amount of quality.

If possible you should always retain the vector information in your type, ideally by leaving your type as an editable text layer, converting it to a smart object or converting it to a shape layer. However, certain filters and tools in Photoshop (depending on which version of Photoshop you are using) can only be used on raster layers. From Photoshop Help / ...

The effect is commonly referred to (but wrongly named) as double exposure but this is merely just clipping an image based on a selection. How this is done Make a selection of your person with the Pen Tool (P) or however you're most comfortable selecting things. Make a Layer Mask, Go to Layer -> Layer Mask -> Reveal Selection. Paste a graphic image ...

You have 4 options, and as for 90% of things done in Photoshop, it's all a matter of skills and using the tools you have. No automatic "floor cleaner" in Photoshop unfortunately. At least one option doesn't require any Photoshop skill at all! 1. Use a broom before taking pictures of shinny surfaces Personally, I really like the Oskar from Vileda. It's ...

It might not be as time-consuming using Photoshop as you think. You can somewhat automate this using the built-in Photomerge tool. For demonstration purposes, I've created a conversation that totally didn't happen using fakephonetext.com. You should first crop out the bits of UI that are repeated in each image, so going along with the example all of the ...

I'd just replace the background altogether. For this quick example I used the Magic Wand to make a selection of the background, inverted the selection, then applied a layer mask and put it on top of a re-colored construction paper texture.
