High Dynamic Range (HDR)

High-dynamic-range imaging (HDRI or HDR) is a method used during photographic image processing which creates a greater dynamic range, between the lightest and darkest areas of an image.

There are two basic methods of doing this; the first is by taking several pictures of your chosen scene or landscape at different exposures and then combining them to create one image. The other method is to re-process a single image several times, increasing and decreasing the exposure, before combining them as before through Photoshop or other HDR software. The outcome can be dramatic; HDR images can therefore represent more accurately the range of image intensity levels, and appear similar to what we see with the human eye.

There are solely HDR cameras and our standard non-HDR cameras, even those with IPhones now have a HDR setting, which can take acceptable images.

We are unashamed exponents of HDR photography and you will see it being used in several of our pictures on this website. We also teach the best methods to obtain your own HDR images. As with many photographic genres, there are those that love it and others who say it is not natural, so it is frowned upon. We believe that by creating an image, which is closer that which we see, it can be very pleasing and therefore is fine by us. When the exponents of film photography (with myself being one who went into the darkroom) many techniques were used to enhance images, so what are we doing now in our software that is so different or less acceptable?

Therefore, HDR balances the exposure levels and with intelligent photo stitching, we can produce a picture that is representative of both dark and bright areas. We would add one note of caution, do not use overly exposed images to your processing stack as they can create to wide a dynamic range and too much burn out will result, which can be too much for some software.
