Anytime I book a trip to a new place I do a google image search for photo hotspots or must see landmarks. I love visiting places like 500px.com that are full of incredible images. This is a great source for inspiration that helps me put together a list of must see locations. However, in doing this, I have found that the online images rarely match what you find in reality. I have found that in many cases it takes a good deal of photoshop afterwards to match the vision that has developed in my head of what the photograph "should" look like as a result of this research. Here are some examples from a few recent trips. I've included the pre-photoshoped images to compare the changes that were made.
Some times these changes can be very time consuming, but in my opinion the final piece of art is well worth the effort.
