Another frequently asked question is how do you cleanup mistakes and messy edges.
Some people are fine with slopping the polish all over the cuticles, and maybe picking it off later, in the shower. In real life, you can sometimes get away with that. But for the purposes of macro pictures, there is little room for error.
A lot of people ask me abut 'the gap'. The gap being the space between the polish and the cuticle. This is achieved in a few ways, but I assure you, in real life it is not nearly as noticeable as it is in macro shots.
Depending on the consistency and colour of the polish, I clean up in a few different ways. One being the classic- run the thumbnail of the other hand down the side of the freshly polished nail' trick. This works well until your get to the second hand and you no longer have an unpolished thumbnail to do this with.
For a quick, easy, not too messy cleanup, I will often use an orange wood stick, sometimes dipped in acetone, or with a tiny bit of fibers from cotton wound around the tip then dipped in acetone.
For a messier mani, or really precise cleanup, I use a tiny, thin, stiff brush dipped in acetone. My favourite is from Joe Fresh, and I think it's likely an eyeliner brush. The eco tools angles eyeliner brush works well too. I dip it in acetone, dab it on the paper towel and run it along the edge of the cuticle. It works wonders. After this, I often apply cuticle oil.
