Focus stacking, typically used for macro shots, where multiple photos are taken with the focus point adjusted slightly between each shot. Briefly, stacking will usually refer to:ġ. Stacking can refer to a number of different techniques, none of which have any particular relationship to HDR or blending. However, if you have a scene where there's lots of complexity where the bright and dark bits meet, blending can be a very time-consuming activity (and, if done wrong, can look even less realistic than an overdone HDR photo). The advantage of this technique over HDR is that it's much easier to get a natural look if the horizon is relatively uncluttered. You can then use a brush to blend the two exposures together. In this case, you would typically take two exposures, one for the ground and one for the sky, and then load them both as layers into your photo-editing software.

Some people like this style of photography (and there's nothing wrong with that), but if you don't, HDR can be a difficult technique to tame.īlending is commonly used to refer to a similar technique, except that instead of using software to automatically combine multiple exposures, you do it manually in Photoshop or another image-editing package. The main downside of HDR, other than the additional work processing the image, is that it can be very easy to make the resulting photo look very unrealistic, with halos, alignment issues, unnatural colours, and so on. HDR is commonly used in cases like that above, where the scene has more brightness than the camera can capture, and you want to get the detail that your eye sees. When you process a single raw file in Lightroom, you are tone-mapping that raw file (which has a higher dynamic range than your monitor) into a low dynamic range photo that can be displayed - that's what the shadows and highlights sliders in Lightroom do. While what is called HDR is usually merging of multiple exposures, as I said above, a modern high-end digital camera has a dynamic range of about 14 stops, whereas a modern display has a dynamic range of about 10 stops. Tone-mapping is actually something a lot of people do all the time without even realising it. The whole process is usually called HDR, but actually, most people never deal with the actual HDR file (the bit created after the combining step), but go straight to tone-mapping it so that it can be displayed properly on a normal display. This tone-mapping is the bit where you play with all the sliders, and it adjusts how the HDR image is 'compressed' (it 'maps' the 'tones' in the image so that they can be displayed). We are then tone-mapping the HDR image into a low dynamic range image that can be displayed properly.

Firstly, the multiple exposures are combined into a single HDR image - this is a photo that contains all of the brightness information, but cannot be displayed on a normal display. What actually is happening when we do 'HDR' is that we (or our software) is performing two separate steps. You can fix either one of these, but not both at the same time.Īccordingly, HDR is used to capture all the detail in the scene, by taking multiple shots at different exposure levels, which clever software can then analyse and take the best bits from each photo.

This has resulted in the detail in the sky being lost in the top right (because it's too bright for the exposure settings), and the detail in the ground being lost in the bottom right (because it's too dark for the exposure settings). For example, this scene had more dynamic range than your camera: This is why some photos cannot capture detail that the eye can see. Modern high-end digital cameras have a dynamic range of about 14 stops, whereas the human eye has a dynamic range closer to 20 stops. This occurs because there is more dynamic range in the scene than the camera can capture in a single photo - you can either choose to capture the sky correctly, or the ground correctly, but not both. You are probably familiar with the situation where the camera turns a blue sky white, or turns the ground nearly black. Most commonly, HDR is used to capture more brightness range than the camera can in a single shot. It often refers to more dynamic range than the camera's sensor can capture, but it can also refer to more dynamic range than a display or printer can reproduce. You may well ask 'more dynamic range than what'. Dynamic range is the number of stops, or levels of brightness, in a photo. HDR, or high dynamic range, refers to a photo that has more dynamic range. HDR and tone-mapping are two halves of the same process, which is commonly, although technically incorrectly, known as a whole as HDR.
