Dynamic Range

The suggested time to spend on this course if you plan to do it in 12 months is about 10 hours a week.   I seem to have spent about that so far on the dynamic range project and I haven’t completed an exercise yet!  It doesn’t help that the weather is grim so the normal conditions for photos such as this are not available bit I thought I had found a reasonable compromise.  Gloss photo paper as a background, some bottles of shiny nail polish sitting on a black lens bag.  As this was taken indoors on a very dull day it was lit by a craft lamp with a daylight bulb.  I then took a series of photos until I had one which was well exposed and had no clipped highlights; f5.6 at 1/5 sec So far so good, I then  expose for the white areas, fine but when I try to expose for the dark areas, the exposure  goes off the scale so I have to start again.

Next problem ….Open the image in your processing software……..Using the software’s pixel value sampler….. what is that and where do I find it?  I have searched the help in both Elements 9 and Lightroom 4 and found nothing.  Then the bit about calculating the range between the 2 ends has me foxed as well as it sounds that this is tied into the exposure adjustments made on the dark areas!  Posted a question on the OCA forum, hopefully someone else will understand this better than I do!


About Anne Bryson

I live in Gloucestershire with my husband Iain and West Highland Terrier, Isla. I enjoy golf, photography and my grandchildren, not necessarily in that order! Having completed a 10 week digital photography course with the Open University in 2010 and wanting to take photography further, I enrolled on the Open College of the Arts BA (Hons) starting with 'The Art of Photography' which I thoroughly enjoyed. Next came Digital Photographic Practice followed by People and Place. In April 2016 I progressed to level two with Documentary and in June 2018 enrolled on my latest OCA course, Landscape.
