Ok, so apparently I've punched a beehive here. Sorry bout that.
Derrell - I didn't mean that to come across as a personal attack or be inflammatory. I always seem to write my most potentially provocative posts right before bed, in the shortest amount of time, with the least tact. So, sorry that you took offense. And sorry if I put words in your mouth. But I was going off the fact that in the past few months, I seem to remember you dismissing quite a few 'portraits' right away for not being vertical.
I completely agree that it is all about understanding, not rules. But rules, when left to themselves, don't teach understanding. I do agree the in most cases there is a better presentation and a worse one. But I'm completely against rules as absolutes, and the idea that one thing is universally right and something else is universally wrong.
There's zero justification for the horizontal on this shot. Room to "breathe?" Sorry. No sale.
It's statements like the above that I have a hard time sitting easy with. And it's statements like this that make me thing of nothing but the rules calling the shots. It's a pretty bold statement to say that there is "zero Justification" for anything in art. At best, you are qualified to say that you see no justification, but no one is qualified to speak sucha justification out of existence. But you've gone one step further by invalidating my opinion because it doesn't line up with what you've come to understand as being 'correct'. I'm sorry, but you don't have the authority to overrule my opinion. The very foundation of art is that it's about appealing to people. Different things appeal to different people, and when the rules try to subjugate art by declaring what someone is or isn't allowed to like the look of, then the chain of command is out of whack.
The rules exist because there are things that generally look better than other things. I'm not against the rules. I think everyone should study them extensively. But ultimately, the rules are not in charge of what people think looks good. The rules were meant to be guidelines to help people recreate what people have already decided they think looks good. Certain things just are more pleasing looking than other things. The rules were meant to serve the tastes of the viewers, not decree what the viewers are allowed to enjoy. Rules have their place in learning, but after they are known and understood, it all comes down to what looks good, which is a personal decision by the artist, and may not be agreed upon by all.
I read all of the links you posted, and none of them went any deeper than a rudimentary and shallow explanation of composition. Most of them just feature people explaining things in extreme brevity, then using bad photos to prove their points. Quite a few of them just used obvious examples of compoistions that don't work in a given format to try and prove the rule. But a few of them were more along the lines of orientation being an important choice, and sometimes one or the other is more appropriate than the other, but it all ultimately comes down to photographer's choice, and that nothing is flat out wrong.
I find the image in question enjoyable. I could maybe do with the top of her head, but it honestly, it doesn't bother me that much. If I were to change it in any way, it would only be to slightly open up the crop. I would leave the orientation the same. I prefer it in horizontal over vertical. The photographer and the OP apparently also like it that way. I visited the photographer's site, and found many more examples of horizontal oriented 'portraits' with the top of heads cut off, and honestly, I don't think many of them looked good at all. That's why the rule exists. Most of the time it doesn't look good. But there are exceptions to every rule. A picture's ultimate job is to connect to the viewer, and if people are connecting to this image, than no rules have the authority to say it's bad photo. You can say you don't like it. You can say it's not a good example of what generally looks good. But you can't say that it is therefore disqualified from being enjoyed by anyone else or that it is wrong.
The rules are a reflection of what looks good. What looks good isn't a reflection of what the rules declare.
Final Disclaimer - I'm still not trying to be inflammatory, nor am I attacking you, nor am I all heated up over here. I"m calm and just debating, so lets keep this cool.
