i have to greatly disagree with you. i know several photographers working in the field professionally and with the introduction of digital technology in photography, professionals are even more likely to use that ease of alteration to their advantage and more frequently. Before, with traditional photography and before photoshop, altering a photo was a lot of work in the dark room, not to mention a very exspensive process if something was not right (lighting, exposure, etc.) The photographers really needed to know their stuff to take high fashion photos, and they got paid good money for their talents.
Today, many many professional photographers use digital and for many reasons. Fixing bad lighting, skin conditions, the weight of a model, saturation, contrast, exposure, etc, can be edited completely in photoshop and other programs. That's why being an apprentice photographer is so much easier because you have all of these tools at your disposal. Many jobs have been lost because of this, and also many more unskilled photographers can use digital technology to fix other-wise crutial mistakes that would, in the past, single out the talent from the amateur.
even if you see the shots they take on americans next top model for each challenge, almost all of those shots are taken digitally and photoshopped to get those girls looking the best they can. (unless an unphotoshopped image is what they are after..........)
