Applying filters
Filters can be applied to layers within your document for corrective or creative purposes.
About filters
In Affinity Photo, filters are available in both non-destructive and destructive forms. A variety of filters are available as Live Filters which are non-destructive.
For destructive filters, it's a great idea to make a duplicate layer of the layer you planned to work on. By applying a filter to the duplicated layer, you preserve the original layer's contents, with the option to hide the 'filter' layer as needed.
If a selection is in place before the filter is applied, the filter will only affect pixels within the selection.
Available filters
BLUR
- 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.
- 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.
SHARPEN
- Clarity (
) — sharpens the image by affecting local contrast.
- High Pass (
) — sharpens image edges.
- Unsharp Mask (
) — sharpens image edges as an alternative to High Pass.
DISTORTIONS
- Deform—distorts from one or more anchor point positions.
- Displace (
) —distorts using a displacement map.
- Lens Distortion (
) —fixes barrel and pincushion lens distortions.
- Mirror—provides a reflection using one or more mirrors.
- Perspective (
) —a filter based on the Perspective Tool.
- Pinch/Punch (
) —squeezes or bulges an image area.
- Pixelate—creates blocks of colour to obscure image areas.
- Polar to Rectangular—distorts by changing polar to rectilinear X/Y coordinates.
- Spherical (
) —creates a convex or concave sphere distortion.
- Rectangular to Polar—distorts by changing rectilinear X/Y to polar coordinates.
- Ripple (
) —produces a radial rippling effect.
- Shear—apply a linear or curved shear to an image horizontally and/or vertically.
- Twirl (
) —creates a clockwise or anti-clockwise twirl effect.
- Affine—moves, scales, or rotates by percentage amounts.
- Equations—apply custom transform filter based on mathematical expressions.
NOISE
- Add Noise (
) —introduces noise to recreate natural texture.
- Clarity—gives contrast-based image sharpening.
- Diffuse (
) —adds noise to image edges.
- Noise Reduction (
) —reduces luminance and colour noise.
- Perlin Noise — Tạo nhiễu hạt giống như hiệu ứng đám mây.
- Dust & Scratches (
) —removes dust and scratch artefacts.
- Deinterlace— converts field based video images to progressive images.
DETECT
- Detect Edges — isolates all edges in your image.
- Detect Horizontal Edges — isolates horizontal edges in your image.
- Detect Vertical Edges — isolates vertical edges in your image.
COLOURS
- Vignette (
) — Tạo hiệu ứng đen 4 góc, tạo thành một vùng phủ hình oval quanh bức ảnh.
- Remove Vignette — fixes unwanted vignetting around your image.
- Defringe (
) — remove colour fringing by sampling.
- Erase White Paper — Chuyển màu trắng thành trong suốt, lưu ý là các màu có pha lẫn trắng cũng bị ảnh hưởng.
- Emboss (
) — creates a convex rounded-edge effect.
- Solarize — sets lightness above which image colours are inverted.
- Halftone — simulates continuous tone reproduction.
- Fill — Fills the layer with a solid colour, history snapshot or inpainting.
- Matte — Chuyển các vùng trong suốt thành các vùng màu solid.
OTHER
- Apply Image — Chèn thêm ảnh vào cùng 1 layer, sử dụng chế độ hòa trộn trong riêng layer đó.
- Lighting (
) — The Lighting feature simulates lighting from one or more light sources.
- Haze Removal — can remove slight to extreme cases of haze affecting an image
THIẾU
- oil color
