That’s lens fungus. You can UV light the lens to kill it but if it’s affecting the pics now that won’t cure it. It will just kill the fungus not repair the glass.

I would be worried about my safety. Doing a photo session in Winter outside? How do you know there will be other people there and this is not just some attempt at getting you alone in a place that’s not going to be filled with people? Something doesn’t feel right here…

You don’t need my camera.

You need to develop an eye for color, composition, to be able to see light, shadows and how they interact. Some of that you can learn. It’s basic tech stuff that is the foundation of good photos but both of my teacher’s they said I had a painter’s eye. I got that because I’m a complete art freak. I study art a lot, always have. I do art outside of photography, draw and paint, so I think that really helps.

Go to museums and look at art and see what the painters were doing. How they used light and shadow, form and color. If you can train your eye to see that then your photography will benefit enormously.

People assuming the “nice camera” is why my photos look so good. Like I am just there to click a button at the right time. :P

My first teacher he made me spend a whole day photographing an egg, watching where the natural light fell throughout the course of the day. It was so slow and so tedious but by the end of the day I understood the purpose of the lesson. Now I find myself looking for where the light is on objects just throughout my day just to see where the light falls, when and how it changes. It helped me a lot in learning the nature of light and how it interacts with things.
