Being a bit of an introvert is not the best thing for a portrait photographer as people are my subject matter and it certainly makes it "interesting" in approaching potential models; and also something I need to really deal with/overcome in the year(s) to come. I also plan on creating a studio space for myself in the coming year so I have a "home base" for shoots. Not every (potential) client has a location to use or wants to shoot outdoors, so a studio space would be very preferable.
I'm still working on defining my personal style; but I'm not sweating it as I know this will come with time. Weather it will be a lighting style, a colour style, high key, low key...maybe I never will have a distinctive style that identifies my work. Not all photographers have an instantly recognizable style.
The latest self portrait shoot eventually ended up with me converting to Black & White, by trying out some of the presets I have in Lightroom. I ended up using one from a collection from Lindsay Adler I purchased as part of a bigger package deal a few months ago. I might have to try it out on some more portraits as I like the look it produces.
