Sometimes it works for your business portrait to be on the low key end. Depending on the purpose and intention of your shoot, different expressions might suit. In this case, we give the example of the most low key pose you can do, straight on.
Don't get us wrong, as abrupt as it may be, it also makes for an instinctively approachable first impression, albeit in a completely different way than an angled pose. With face on shots, there's nothing to hide and you have all your cards on the table. This psychologically evokes trust, and straight forwardness, which is ultimately an attractive quality in humans!
