HDR Photography
HDR (High Dynamic Range) images attempt to show the full detail within a scene like how it would be seen by the human eye. Cameras have a range that is only a quarter of what the human eye can see so frequently photographs can be too dark or burned out in areas. Software can be used to merge different exposures of the same image so that the parts that are shadows and the parts that are highlights can appear to be correctly exposed giving a simmilar range to the human eye. HDR software is now at a point where seperate exposures can be merged to HDR quickly and intelligently giving excellent results.
I have a lot of experience of using HDR software, I have become quite competent with the technique and well aware of what it can and can't do.
In my opinion there are two main types of image that can be achieved through HDR. The hyper-real, super vibrant type which is commonly used to shoot things like churches and landscapes. When used correctly this effect can be very eye-catching and result in some stunning photographs. When misused, this effect can be over powering and can sometimes detract from a photograph, you commonly see photographers using this type of HDR to distract you from noticing badly composed photographs. Personally i don't think relying on HDR to make badly composed photographs appear good is worth while, and the use of HDR should always come second to subjects, composition and in-camera settings.
The second type of HDR is in my opinion the better way to make use of it, under most circumstances this is the way i tend to use it.
This type is where photographs are only enhanced with HDR if it will genuinely improve the photograph by correcting any ill-exposed areas of a photograph caused by using average meter readings when shooting.
With the aim of improving exposure in mind, using HDR should make all areas of a photograph correctly exposed leading to, in most cases, a vastly improved photograph, But also a photograph which retains its credibility.
