I am so ready to do more plein air painting but summer heat has other plans. Basically the sun doesn't like me that much. So in my opinion it is ok then to take a photo and paint it later.
The pro is, there is AC... comfortable chair, desk etc.
The con is you are much slower and more detailed.
I always try to do all kinds of styles and find what is working for me in different situations.
Practice give confidence. You do not need perfection in art. You need not to stop. To grow confidence. And to have fun creating.
I took a few photos in Main street, Old Town Tustin. Painted at home.
