Painting taught me to observe even more as a photographer. Although, I will say that contemporary painters have an obsession about mark making as how the paint is put down on the surface. My instructors would always tell me to not go back over a mark once I had made it. However, the retinal painting studies that I did made in Painting I and color studies made me see far more in the world around me as far as color and form. Every medium I have worked in has had an influence on me.
This is an interesting thread in my opinion. I also do both - painting / sketching and photography. I feel that both benefit from each other even if they are different.
For me producing a photography is in some aspects similar to producing a painting - at least if the painting is done in front of the scene. In both cases placing the objects in a balanced (or purposely unbalanced) composition by changing ones own position and the placement of the different objects inside the image borders is crucial. But in a painting one has more freedom to accentuate the different things like one sees and feels them. In both, painting and photography, unconscious decisions take place - however in photography they are quick actions and one does not realize them directly - while during painting this is the thing which constitutes the main fun for me: how the painting is formed on the paper 'by itself' without thinking too much.
Maybe I can illustrate this with two examples: I recently sketched two images quickly with felt pens: one in front of a night scene and one of some old tires in the wood - and today I got the slide film back from development with the photos I made of theses scenes too. I find it interesting that for the night scene the painting is much more different to the photo - the painting representing more truly how I saw and felt the scene.
In my humble opinion photographers would be a lot better served if they stopped naval gazing and worrying how their craft was the poor relation of Fine Art, (which there seems to so much anxiety about on this and other photography forums), and just concentrated on shooting the best pictures they are capable of.
Though I appreciate the discussion of the concept (and is see so little of this type of discussion on forums, so I'm delighted to see it here), there's such a range of quality and ability of the people in both fields that making the type of generalization that was proposed seem a bit like trying to decide what color is a shirt.
I suspect, however, that the very best people in virtually any field are the ones who are the most observant, and that this cuts across everything from drawing and photography to things like farming and selling shoes.
I think your post shows just how difficult photography is. Both photos are basically just snaps with poor lighting and poor composition. But in your "mind's eye" you were able to see the true light and content and paint it as it would have been if the lighting conditions and perspectives were better. With a camera, the photos fail.
The painter is blessed with a blank canvas. He only puts in the things he wants in the way that will make it aesthetically pleasing and/or to accentutate the content. The photographer starts with a full canvas containing all sorts of things he has to get rid of and force perspective, lighting and other issues to eliminate the things that detract. A more difficult process.
By the way , I like your sketches.
Another thing about your sketches and photos is that they create a learning experience for all of us. And that is how balance and "rules" of composition apply to painting and photos.
In your building picture, the right negative area was eliminated in your sketch. The tree was inserted in a more balanced position against the weight of the dome. One can see the "rule of thirds" at work.
Likewise in the tire shots, the negative space on the bottom and right were cropped out in your sketch something I could have done with the photos as well to make them better. It created a pleasing balance in the shot.
There's a lot photographers can learn from painters about composition, balance, content, lighting etc. Yesterday while waiting in a doctor's office, I was looking through their magazines in the waiting room. Some were painting art related. I was impressed by how so much of what photographers should learn come from the experiences of painters.
