Hi jonib101,
I've been watching this thread for a while; I wasn't going to reply as there had already been feedback on the work and there's no point in just repeating what others have said, however I've had to respond to some of the....less helpful....comments that have been put on here. Why? Because I thought this forum was supposed to be helpful to newcomers, I thought I'd finally stumbled across one that didn't operate as a click, I thought the replies (whilst being repetitive) were on the whole, fairly well balanced and to the point but, God help me, I think I've just be lured into a false sense of security...
First, just your initial question, can you call yourself a professional and charge for your work? The difference between pro and amatuer is that a pro charges for their work, there isn't a level of quality where you move from one to the other, despite people expecting it when they hear professional. What you should have probably asked is will your work be good enough to earn a living from photography? I'd say yes, it will be, against the common grain of the threads here I think your work is good for starting. There are certain points you need to read up on, DOF, affect of zoom etc etc etc, but they'll not take long for you to understand. You will need a pro camera, SLR, MF or whatever, but that's not going to make or break your work. If you're a good photographer you'll take a good photograph with your phone, if you're a bad photographer, you can mix a Canon EOS 1Ds Mk3 with Lightroom 3 and Photoshop CS5 and a big, fat, juicy memory card and it'll not make any difference, your work will still be awful.
If someone is happy with your work and is happy to pay you, that's the real acid test, the proof of the pudding and the rest, not what someone here tells you about how they don't like your style....or that you're going to be sued.
Now...
Derrel, you're reply wasn't helpful and was, bluntly, incorrect. It wasn't helpful because, when I read it, it came across as unbelievably patronising. You're incorrect because (a) you don't have to rotate...camera....to portrait....orientation, it's commonly held that cropping up to half the forehead makes for a very good portrait and (b) Jonib101 didn't 'butcher' 5 out of 5 portraits.
KmH...what sort of 'help' is that? Yes, there are areas of photography business that are not to do with photography, people sort them out when they are required to. But in the vein of your reply; were you asked about them? Are you a professional tax / business advisor? Do you honestly, really, truly, think your reply was useful, answering the question asked, or leading the discussion onwards? I don't.
ivomitcats, do you cross a road at all, because people have actually been killed by passing cars. It's happened before. Do you fly at all, because people have actually been killed in plane crashes. It's happened before. Do you stick your face in a fan at all....well, I'm sure you know where this is going...like KmH, you're not really leading the discussion onward with this, all you're doing is scaremongering and making unrelated points.
Now before someone jumps up all bloated with righteous indignation and froths at the mouth typing a reply tellng me I'm wrong because 'he's been thanked 1,000 times in half a thread' or 'she's written over 1,000,000 threads in a day' or 'they've got a really long lens on their camera' read my signature and ask yourself is it worth it?
