Over 100 powerful image editing tools, presented in the simplest user interface. Like most workshops, you use several tools to accomplish a task. Core Image Tools is a large toolbox to reach into, to accomplish many complex effects, one simple step at a time. Lightweight yet Powerful: Edit, enhance, resize, rotate, & add effects to your photos|images from the palm of your hand, while you're on the go, or also from your desktop|laptop. Multi-Platform: Use the same app across your devices - iPhones, iPads, Macs, & Vision. Super-Simple Workflow: Pick a Photos image, apply an effect, tap save - done! Want more? Pick that saved image, apply some other effect to it, tap save - done! Loop the image through as many edits|effects as desired & always have a hardcopy in Photos of each step along the way. Plus you'll always have your original, & never had to type in a single filename throughout the entire process. Resize Images: ACTUALLY resize images, not just crop them down or zoom in. Also, you can ADD color|transparent|semi-transparent pixels to any edge of an image to resize it, or offset it, using 'Border | Underlay'. Flip|Mirror: Quickly mask|mirror a brand name out of your selfie. Flip|mirror an image, horizontally and|or vertically, with one tap. Use 'Skew' to straighten, keystone-correct, zoom, mirror, & crop all at once. Smooth: Use 'Blur, Selfie Smoother' to iron out a few wrinkles, de-focus skin blemishes, or smooth out other unwanted details. Line|Edge Drawn: Make an image look as if it was drawn|sketched using an ink pen, pencil, charcoal, colored pencils, colored chalk, light-pen, watercolored, wax-scratched (scratch-art), or made entirely out of dots|square pixels|points|hex-pixels|or crystalized. Bump Distortion: Kids of all ages (Mom? Dad?) love to swell up, or shrink down, faces & parts of people - give dad a superhero chin, a sibling one big eye & one little one, a bubbled alien-forehead of a friend - endless fun. Wish you had a smaller nose - shrink it. Wish you had bigger biceps or shoulders - pump 'em up. Wonder what implants would look like - find out. Zoom in on, & bring attention to, any feature in an image, especially for technical uses, like highlighting a capacitor on a PCB, or a component of a wiring schematic. Overlay Images: Including resizing, repositioning, & rotating them. Overlay your logo or business card over an image. Also, you can make an entire image of a transparent, or semi-transparent color & overlay that over your image, adding a color filter effect to the entire image. Chroma-Keyers (6 types!): Remove red, green, or blue-screen, or any color. Maybe make transparent overlays out of them? Maybe use 'Polygon | Star' to make color-keyed shapes for transparency masks. Checkerboard: Make checkerboard designs - just pick your colors, including clear|transparent. Blurs: Gaussian Blur, Zoom Blur, Motion Blur, Glow|Bloom, & other blur effects. 3D|Graphics|Cube Images: Make your textures|shaders, tile them, rotate them, make normal|bump maps from them for enhanced lighting effects. Mirrored|seamless tiles, multicolored gradients (linear & radial, plus gradients scale perfectly & tile infinitely from one small image - very efficient). Use 'Alpha as Grayscale' to map out image transparencies for your texture|shader's opacity channel. The best skybox|cube image tools too! Color & Light Adjusters: Many options - brightness, contrast, saturation, exposure, gamma, vibrance, opacity. Try 'Dark Document Enhancer' on a dark document or a scan that you want to enhance. Grayscale Images: Select from 7 grayscale modes each honed for specific imaging challenges. Animated Image Player: Play, pause, slow down, speed-up, & reverse animated images. Kaleidoscopes: Do you like kaleidoscopes? Oh yeah! Gotcha covered there! Over a dozen types. Infinite possibilities just from one image, & the default image is of the most beautifully colored flowers. Developers: Make App Icons, Buttons, & Radio buttons.
