High Dynamic Range Photo.

#1 Post by GrahameA » Wed Feb 19, 2014 8:21 am

Morning All.

One of the issues with digital photography is that it does not have the dynamic range of film. However there are techniques that can be used to create an image that emulates the dynamic range of film.

This is an example of a HDR (High Dynamic Range) image. It was taken around 7:39 pm on Saturday 15/02/14. The final result is a montage of three images with three different exposure so that the "blacks" are black and the "whites" are white.

Afternoon.

Another HDR Photo. The points to note are that the highlights are not blown out due to being over exposed and at the same time there is still detail in the dark area rather than them being just under exposed and lost.

'Evening.

It is an effective technique isn't it?

Really "pops" off the page (or in this case, the screen).

Cheers!

Yes. However, it is only really suitable to stationary images.

Some films equally give some 'pop' due to the dyes/processing.

I will continue to experiment with the method just learn a bit more of what it capable of. Night subjects with the extremes of light and shade seem to offer ideal opportunities.

Grahame, you kept the same aperture for the 3 exposures? Just different exposure times? Excellent results mate.

It is more prudent to vay the exposure time rather than the aperture otherwise you run a risk of varying what is in focus.
