nmbcb4 Posted December 22, 2015 Share Posted December 22, 2015 Photoshop's Maximum and Minimum filters are useful for modifying masks. The Maximum filter has the effect of applying a spread (dilation)—spreading out white areas and choking in black areas. The Minimum filter has the effect of applying a choke (erosion)—shrinking white areas and spreading out the black areas. Like the Median filter, the Maximum and Minimum filters operate on selected pixels. Within a specified radius, the Maximum and Minimum filters replace the current pixel’s brightness value with the highest or lowest brightness value of the surrounding pixels. These filters, especially with larger radii, tend to promote either corners or curves in the image contours. In Photoshop CC, you can choose from the Preserve menu to favor squareness or roundness as you specify the radius value. I'll be needing a close approximation of these filters to justify making a break from Photoshop. Does Affinity Photo have the equivalent of Photoshop's Maximum & Minimum filters?

anon1 Posted December 23, 2015 Share Posted December 23, 2015 From the Affinity Photo Help: Maximum Blur The Maximum Blur filter broadens highlight regions in the image, and shrinks darker areas. It works by comparing each pixel to its neighbor and replaces darker pixels with lighter pixels. This is most useful for modifying masks. // and there is an option to have it (non) circular Minimum Blur The Minimum Blur filter shrinks highlight regions in the image, and broadens darker areas. It works by comparing each pixel to its neighbor and replaces lighter pixels with darker pixels. This is most useful for modifying masks. // Maximum and Minimum blur are one of those filter that are not live filters though, which means they´re destructive Blur Filters: Use blur filters to apply creative blurring effects to your photo. Available filters include: Average—applies a uniform colour averaged across your image. Bilateral Blur—blurs while retaining high contrast. Box Blur—blurs based on a boxed region. Custom Blur—applies your own blur using a customizable pixel matrix. // maybe this is also something for your interest? ;) Depth Of Field Blur—applies elliptical or Tilt-shift blur gradients. Diffuse Glow—blurs with a soft glow effect. Field Blur—adds focal points to a blurred image. Gaussian Blur—a smoothing blur for noise reduction. Lens Blur— simulates blurring from wide aperture lens usage. Maximum Blur—broadens highlights, reduce shadows. Median Blur—blurs while affecting colour regions. Minimum Blur—shrinks highlights, increase shadows. Motion Blur—blurs to simulate directional movement. Radial Blur—gives a circular blur at a chosen position. Zoom Blur—blurs to simulate zooming-in motion effect. hope this helps :) Kal, Depa, m2gdh and 2 others 5 Quote Link to comment Share on other sites More sharing options...
