i saw tons of people buy DSLR in the last few years.
Most used as overpriced P&S because they did not know what SLR's are capable or did not have interest in learning or did not have time.
Given that many P&S and smartphone cameras have "effects"to get the desired effect they realized that they do not need no longer needed a DSLR to shoot, download and edit.
i have a friend who bought a 600D because he liked my pictures.
now he is complaining that everything is "so unsharp" with his DSLR when he takes pictures for his ebay auctions.
i (tried to) teach him about aperture but he still doesn´t really gets why, with his 190 euro P&S everything was sharp and now his pictures are "unsharp".
"there must be a way this DSLR makes sharp photos from back to front without all this raising ISO because of smaller aperture stuff ... or buying a speedlight??"
DOF is some strange concept for people who only shoot with a P&S before.
he also complains that his images don´t show as much details as mine. "you are sure this camera is not broken? your camera makes much better images".
his problem is, when he does portraits the head only occupies 1/6 of the frame and then he crops like mad. told him a few times to get closer... he makes the same errors again and again.
some people really don´t need a DSLR.
he likes my macro and portrait shots but even after 16 month he still takes pictures in P mode.
and he wonders that with the "expensive" DSLR his images doesn´t look much better then with his 190 euro P&S. for him light is light..... you only need enough.
i still try to teach him a bit.... but it´s hard work.
