HDR

HDR, or High dynamic range imaging, is a set of methods in image making and photography to capture a greater dynamic range between the lightest and darkest areas of an image. HDR images can represent, more accurately, the range of intensity levels found in real scenes, from direct sunlight to faint starlight, and is often captured by a plurality of differently exposed images of the same subject matter. This is called bracketing. Non-HDR cameras take pictures at one exposure level with a limited contrast range. This results in a loss of detail in both the light and dark areas of the image depending on whether the camera had a low or high exposure setting. However any camera that allows you to control the exposure setting can create a HDR image. HDR compensates for this loss of detail by taking multiple pictures at different exposure levels and intelligently stitching them together to produce a picture that is representative of both light and dark areas. 


I tried making a HDR image using just one image in photoshop and here is how i did it.

First I opened the image in photoshop, then i made an under exposed and over exposed version of the image. 

This was the over exposed image. 

Then I opened the images up in Adobe bridge and I Merged them to HDR using photoshop. 



I selected all three images, chose tools and selected 'Merge to HDR'.

The image didnt really work very well and this was my end result.



My end result wasn't the result i was looking for. I dont know what happened to this image.


I tried to do this with another image, and this was my process and result. 






I was very happy with my final result and i think it worked very well!
