Understanding
Sometimes you have to help the viewer understanding your pictures.
One challenge could be understanding sizes. Like it is a very small or very big object. An easy solution is to add to the picture something the viewer familiar with. Like have a person on the picture. That is what I’ve done to help you see how big are the caves!
To make this picture I also had an understanding challenge. As I’ve said these caves are close to the Croatian-Slovenian border – you have to be cautious no to cross the border! We were walking for hours and we knew that the caves must be close … somewhere. Suddenly we spotted a rock on the road with an arrow to the left and some text … in Slovenian. So we have found – go to the left! Luckily my friend could read & understand it. It says: do not go to the left as you would cross the border :) So the caves were to the right.
Did you use HDR for these shots?
Many time I shoot a bracketed series however I use only one pic. I edit in Lightroom or Capture NX. My camera’s raw has lots of dynamics so I find all these details in one shot. However highlights, shadows local exposure corrections make HDR effect :)
