Turn any photo into a dot grid artwork with these Photoshop actions. You'll get great results with dots that change size. They get larger in brighter areas and smaller in darker areas. Free download available.
High dynamic range
In the real world, the dynamic range far exceeds what our eyes are capable of seeing and what our monitors and printers are capable of displaying. With high dynamic range (HDR) images, you can create images that can store a larger dynamic range. In the example below, a single exposure photograph doesn't capture enough dynamic range to display all the details; no exposure setting could display the correct dynamic range. Photoshop was used to merge three exposures to capture more dynamic range.
Photograph for HDR
If you want to shoot photos and use the Merge to HDR command in Photoshop to create a HDR photo, remember the following tips:- The images must be of the same scene. Place the camera on a tripod before shooting.
- Shoot at different exposure settings to capture the full dynamic range in the scene. You will need at least three photos to use the Merge to HDR command but we recommend at least five for best results.
- Set your camera to Manual mode and adjust the shutter speed to create images with different exposure. You can sometimes get away with using the auto-bracket in your camera but the exposure changes are usually too small. Do not adjust the aperture or ISO because those will alter the depth of field, noise, or vignette in the photo.
- The exposure difference between the photos should be at least one or two EV steps apart. If you are using a camera with low dynamic range, such as a point and shoot camera with a small sensor size, the photos should be one EV step apart. On higher quality cameras such as DSLR's with larger sensors and wider dynamic range, the images can be two EV steps apart. There is usually no benefit to using smaller EV steps.
- The scene in all the images should be identical. Do not photograph moving objects such as cars, people, or landscapes on a windy day. If you use flash, make sure that you use the same flash output for all the images.
- Shoot in RAW mode instead of JPEG for better dynamic range.
Merge to HDR command
The Merge to HDR command in Photoshop lets you combine several of the same scene with different exposures into a single HDR 32-bpc (bits-per-channel) image. First, you'll need to have three images taken at different exposures. Run Photoshop and choose File > Automate > Merge to HDR.
