I think the shots look ‘posed’.
All my work is done posed; I very rarely shoot candids these days. These were taken from a formal session though, which is different to how I normally work (which is in the moment, in the street).
I think you’re identifying that you’re not keen on portrait photography, which is fine and I don’t take it as a criticism. I also think it’s important to not anchor your opinion to whether you have the ability to execute things yourself. Your opinion can be just as valid (and I welcome it).
Possibly what you’re articulating is the ability to capture a person’s true self without it looking too contrived? That is much more difficult to do. The colour photograph though has had people who know the subject unanimously declaring that that is absolutely her but you would only know that if you knew her. It also doesn’t mean that the pose she is holding isn’t, as you say, entirely posed. I had her very deliberately hold this position. It is possible to achieve the sense of the person without directing them, but that is the part that is much harder to achieve and where I still have a lot of work to develop as a skill.
To be honest, I’ve been thinking a lot lately about the value and athenticity of photographic portraiture in general. I have some doubts even though I am deeply wedded to the idea!
