What is HDR exactly? Wikipedia tell us:
In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allow a greater dynamic range of luminances between the lightest and darkest areas of an image than standard digital imaging techniques or photographic methods. This wider dynamic range allows HDR images to more accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.
The two main sources of HDR imagery are computer renderings and merging of multiple photographs, which in turn are known as low dynamic range (LDR) (also called standard dynamic range (SDR)) photographs.
Tone mapping techniques, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect. More...
If you want to try make HDR images, you have to be careful. Because you use 2 or 3 images and when you have noise or another artefact on image, they be multiply!
HDR is an interesting concept. Your HDR images are nice, but some people do extreme HDR that is extremely surreal and has lots of haloing, and ghosting, sometimes. I rarely like those images. I've seen HDR used very well, and I've seen many lousy HDR images. It can be a powerful tool if used right.
Gmargittai, what they say about noise I couldnt find in my images, even when using many images together, I still find lots of noise, so I rather get them piled on photoshop and paint on the masks, I get to results with the best quality and very low noise. But, maybe I dont know very well how to use HDR software anyway.
They say an HDR image is great when it does not cry out HDR from a distance. It has to be discrete. It has to help render the image as it should be rather than exaggerating it. But as they say each one with his/her own taste. I am sometimes using HDR in my images. The main advantage I get from this is a better saturation and less noise. Why? Because by combining two images the random noise is decreased and also one uses the sensor closer to its median value where it is the best, Not too dark not too light.
Well, to tell the truth, I don't like HDR images. I sometimes use this technique to remove too white or too dark parts of a photo (for example: https://www.dreamstime.com/lonely-woman-waiting-image11055697 -made from one raw with three exposure level), but I'm aware of using it so hardly....I don't like those graphic, not-real clouds...sorry. Anyway, I'm not a Buyer ;)
Hi, Sebikus, not only HDR tone mapped to LDR can be used to generate hyper realistic images like your two images at this blog, but also realistic images where the dynamic range exceeds the camera capability, like, say, in a washed sky day. Thats how I´ve been using it. The hyper realistic look is cool too, though, and they look really nice on those two examples of yours.
