Sometimes a photo-worthy moment happens so quickly that it’s near impossible to compose the frame properly, like when a great white pelican suddenly appears next to your boat.
At moments like this, a messy, distracting backdrop is often hard to avoid. Here, the metal bars intrude on the composition rather than enhance it. But if we like we can remove distractions like this with simple retouching tools in Affinity Photo.
One of the most powerful is the Inpainting tool. It’s a clever feature that’s conveniently easy to use, even for a complete beginner. We simply paint over parts of the image and the tool intelligently analyses the area, determines what we’d like to remove, then replaces the offending pixels by sampling and replicating those nearby. Here it means we can add extra waves to cover the bars.
Of course, like all automated tools it’s not infallible. It works brilliantly for removing imperfections against otherwise clean areas, like a pimple on skin or a sensor mark in a sky. But when the object we’re attempting to remove intersects with something we want to preserve – like where the bars meet the body of the bird here – the result can be a blotchy mess.
However, there are steps we can take to prevent this happening. Here we can use the Clone tool to ‘cut off’ the bars where they intersect the body of the bird, then use Inpainting to finish off. By employing Affinity’s intelligent selection tools, it’s a quick and easy task.
The Selection Brush works very similarly to any other brush, allowing you to paint a selection over your image. But the clever part is the way it seeks out edges and changes in colour or tone as you paint. This makes it easy to snap the selection to the edges of complex objects like the bird we have here. If the tool manages to accidentally pick up unwanted areas in the selection, click the subtract button at top left (or hold Alt) and paint to remove areas until it’s perfect.
Step 1: Remove the bar
We've opened our image in Affinity photo and headed to the Layers panel to click the New Layer icon at the bottom. Next, we grab the Inpainting tool from the toolbar (next to the healing tools). After we set ‘Current and Below’ in the tool options at the top, we zoom in close and paint over the bar to the right of the bird’s head.
Step 2: Clone to tidy
The Inpainting can leave slight blotchiness along the edge of the correction, so we switch to the Clone Tool (S) and again set ‘Current and Below’ in the options, then hold Alt to sample a clean part of the sea or bird near to the messy area. Now we can paint to clone the pixels from one place to another.
Step 3: Select the bird
Often it makes our cloning easier if we first select which parts to isolate in the image. Here, we grab the Selection Brush and highlight the bottom layer, then paint over the bird to select it. The tool automatically snaps to the edges. Now we can go to Select > Refine Edges then increase the Radius slightly and hit OK.
Step 4: Clone the edges
Now we go to Select > Invert Pixel Selection. We highlight the upper layer again then grab the Clone tool. We can zoom in close and then clone along the edges in order to break the connection between the messy metal bars and the edges where they intersect the bird’s body. When sampling areas like these, try to follow any lines in the background, like the lines of the waves here.
Step 5: Paint over the bars
We can grab the Inpainting tool again then carefully paint over the remaining bars in our photo's background. Now, because the bars are not ‘connected’ to the body of the bird, the results of using the Inpainting tool are much better than if we were to simply paint over the bars without first cloning the edges.
Step 6: Finish it off
To finish off, we hit Cmd/Ctrl+D to deselect then zoom in and check all the edges for blurriness or mess. The Clone tool is useful for blending rough pixels when used at a low opacity. Here, we set the tool opacity to 30% then Alt-click to sample a nearby source and clone away any remaining messy pixels.
The Selection Brush is one of the most powerful tools available in Affinity Photo.
It works very similarly to any other brush, allowing you to paint a selection over your image. But the clever part is the way it seeks out edges and changes in colour or tone as you paint. This makes it easy to snap the selection to the edges of complex objects like the bird we have here.
