I have 20 years experience by PhotoShop, especially with editing photos of Architecture, Tourism and Landscape. I havn't had job in here yet but given that I am an Aerial Archaeologist I have spent so many hours in the aircraft with camera and editing photos after flight for scientific papers, ppt, web etc. The same is with photos from every outdoors activity - hiking, camping, tourist traveling and archaeological excavation. Editing photos with a landscape and architectural contents refer to recover data from a raw photography and also making them really vivid and colorful, useful for various purposes.
With а bit of PhotoShop every photo may be slightly work of art.
Old and damaged photo restoration
Recreating missing areas in photos
Increasing image size without compromising on the quality of the photography
Removing/adding background, persons and sky/unwanted objects.
Enhancing/adjusting color, lightening contrast
Background editing - white/ transparent/ different
The scope of PhotoShop activities is enormous and it is difficult to describe all, so I'm ready to talk about any special wishes or ideas related to image editing.
