The way I look at it, no two photographs are ever the same. How can they be? The variables are just to great such as light, time of day or season, composition, camera settings, etc. What you shoot is going to be your own vision of what the location looks like.
Do I think it is good practice to look for more original and fresh locations, you bet I do! That's what makes photography so much fun. Finding a new location or composition is always very rewarding and productive. As photographers when we walk and explore we are always looking for a photographic opportunity. I always carry my camera because I never know when a great image possibility will present itself.
It brings me constant joy as I walk through my home and see my images reminding me of the experience of that location. It makes the difficulty of getting the image very worthwhile. If the image is at an "Iconic" location I enjoy it just the same as any other image I shot that was " wall hanging quality ".
The bottom line as landscape photographers we just want to make the best image possible in the presentation and light that is offered to us at any given time. If the location is what you want and you want that prize image, then shoot it. It is your vision and art for you and others to enjoy. To me this is what photography is all about. Being at the most beautiful and interesting locations and recording that moment for yourself. You never know if you will have the opportunity to return, so shoot away!!
Until next time may the best of light follow you!
