Landscape photographers often blend images shot at different focal distances for maximum sharpness and occasionally those shot at separate focal lengths for creative effect. However, you can also blend images shot at different shutter speeds for both creative effect and high levels of sharpness, and this excellent video tutorial will show you how to do it using Photoshop.
Coming to you from Adam Gibbs, this great video tutorial will show you how to blend images shot at different shutter speeds using Photoshop. This is a very useful technique that can really help you level up your landscape images. We often shoot at very long shutter speeds for the purposes of showing the flow of water or the like, but if that water is surrounded by foliage and there is any sort of wind, this can rob those areas of your image of sharpness. So, in this case, the best way to handle it is to shoot the water with a long shutter speed for creative effect and the rest of the frame with a short shutter speed to freeze any motion, then to blend the two in Photoshop. Check out the video above for the full rundown from Gibbs.
