Just a few HDR photos

Just a few HDR images I took to day

 

Hi " M " it stands for,High Dynamic Range

When you look at a scene, there will probably be a range of how bright things are. We can assign a brightness value to each thing/area...in EVs (exposure value). So for example, the sky might be EV12, the landscape might have areas of EV8, EV6 and EV4. So to calculate the dynamic range of the scene, you take the brightest value and subtract the lowest (12-4) and we come up with a dynamic range of 8EV (or 8 'stops').

Now we need to realize that our cameras are only capable of recording detail within it's own dynamic range. For the most part, digital SLR camera are capturing about 4-5 stops (while maintaining good quality).
So when you go to take a photo of a scene that exceeds your camera's dynamic range...you will have to make a compromise. If you expose for the shadows, the highlights will be blown out (white). If you expose for the highlights, then the shadows will be black with no detail. So it has been our task, as photographers, to make this choice and expose for what we deem to be the most important parts of our scene (or do something to alleviate the problem).

One way to get around this problem, is the HDR technique. (High Dynamic Range). With this technique, rather than choosing one exposure, you take several photos at different exposure values...exposing for the shadows and the highlights. You then use software to take the best parts from each image and combine them into one image, which will have a greater dynamic range than you could ever capture in a single photo.

 

Brilliant explanation.

honest opinion - colour superb but I have trouble looking at the pictures as they hurt my eyes. . It's slightly out of register, similar to 3D pictures and my eyes are very sensitive to it.

Poor, sensitive, dear!!

 

Thank you Shiney my friend I will try to make them a little easier on the eyes,I know just what you mean

To day

 

Good morning Sheal and thank you I have put a poll up in a friendly way just to see what our members think about HDR Images,I guess you will be voting NO

Bearing in mind that enlarged to a poster size and nicely framed they can look good

 

Sorry, Woo, but although they are much better than they were, they still hurt my eyes as they are still slightly out of register. They still have the slight effect of looking like 3D pictures without the special glasses.

 

Good morning Shiney no worries my friend all photos look like that to me
