Watch video: How to blend photos from two different focal lengths
One of the great joys of landscape photography is when you’re treated to a combination of enticing foreground details and elements in distant scenery. But composing this into a balanced frame can sometimes be a challenge.
If we use a wide-angle lens to shoot the foreground details – due to the exaggerated perspective – the backdrop can become too small and insignificant. Here, for example, the blurred water in the foreground plays an important part, but to capture it we needed to use a wide-angle lens.
This left the focal point beyond – the Pontsticill Reservoir in Wales – too small. Focal length blending offers a way to get around this. By taking two frames at different focal lengths – one wide, one longer – then blending them, we can enlarge the background.
Compositing in landscape photography is a contentious issue. But combining two versions of the scene like this may arguably bring us closer to how the scene feels in the flesh. Our eyes don’t work like super-wide angle lenses (they’re more like a combination of a sharp 50mm in the center and a blurry 20mm around the edges).
So the exaggerated perspective you get with wide angles – with oversized foreground details and minuscule distant scenery – often feels vastly different to the view when you’re looking at a scene with your own eyes. Blending two focal lengths could be closer to the experience of being there…
1. Prepare your images
Open your images in Adobe Photoshop (if toning in Lightroom first, ensure that both images have identical adjustments). Analyze the scene in the wider of the two images and determine where the easiest join line will be. Here, the dark banks of the lake are ideal.
2. Copy and position
Go to the zoomed-in image then grab the Move tool. Drag it to the tab of the other image and then down and in to copy it over. Lower the layer opacity to around 50% then hit Cmd/Ctrl + T. Use the bounding box to transform, resize and position the image to fit.
3. Paint a mask
Bring the layer opacity back to 100%. Click the Add Layer Mask icon in the Layers Panel then grab the Brush tool. Paint with black to hide parts of the long image so that it blends with the wide scene. Use a soft-edged brush tip for a gentle transition.
4. Fine tune the blend
Zoom in close to check the edges of the layer, making sure that the blend looks natural. Using a smaller brush, paint with black to hide parts or hit X to switch to white and paint to reveal hidden areas. You can also paint at a lower opacity for a gentle transition.
5. Clone to tidy
Make a new layer and then grab the Clone tool. We can use it to tidy any rough areas in the composite. Set it to Sample: All Layers in the tool options at the top, then hold Alt and click to sample a clean area and paint to clone over any sketchy patches.
6. Final toning
Hit Cmd/Ctrl + Shift + Alt + E to merge a copy of all the layers, then go to Filter > Camera Raw Filter. Try the color-shifting presets in the Profile Browser (click the grid icon in the Basic Panel to access it). Make any other tonal changes or local adjustments you like to finish.
