Impact Images

HDR (High Dynamic Range) The art of blending multiple exposures, you can create images with incredible detail and photos that mimic fine art paintings and surrealistic imagery.

HOW DOES IT WORK ? When the human eye scans a scene, the pupil dilates and contracts, this enables us to quickly look around and perceive detail in all but the brightest and dimmest conditions. When we take a photograph, we have to decide what length of exposure to use in order that the important parts of the photograph are in detail, this means certain areas of the photograph may suffer as a result of under, or over exposures.

TAKING YOUR PHOTOS, Have your camera on a tripod if you wish to get sharp results, I take three photos each at a different exposure using the Auto Exposure Bracketing - a setting most DSLRs will now have, I take the three photos in quick succession.

CREATING THE HDR, Once I have the images on my laptop, I need to convert them into a single HDR image. The software I use is Photomatix  , This software will merge all the three images into one single image using the best exposure from each, the finished result is an image showing a Higher Dynamic Range of exposure to the overall image.

The three photos above are the original RAW images, the lower larger image is the finished result. Please note that the finished image was later straightened and further work carried out using Photoshop CS4.
