I still do not have a good professional photograph of me looking like a Serious Geologist In the Field. But I had some downtime in a scenic area, waiting for yet another part to be delivered, I wasn't actively burnt and/or rashy from poison ivy, and I thought, "hell, I'm just sitting here. I'll take my own damn photograph!".
Man, hot day + sunscreen + logging soil samples and brushing at stray bugs means I am really not going to get a professional looking photograph in the field. Ladies in the movies can look dewy and/or artfully grease-stained. I just look gross.
