When I'm focused and giving it my all, it's like I'm in a tunnel. It's actually a miracle that I haven't fallen off a cliff yet. But joking aside! There have been two minor accidents on my past trips. Once the model fell naked off a longboard and suffered bloody wounds on the road. I didn't take any photos of this, but took care of her right away.
The other time, I filmed a model running on the beach and ran backwards myself. Stupidly, a 50cm high lava rock with razor-sharp edges was sticking out of the sand and it caught me. Fortunately, I reacted quickly and was able to jump up at the first contact so that I didn't fall onto the rock. But I still bled.
What I'm actually getting at is that if something like that happens to you, you need bandages. And I've now found out that rental cars practically always lack this. These things also happen on public holidays or at times when pharmacies are already closed.
But it is much more important to be careful. Never run backwards, don't walk too close to the edge and so on. I know, I sound like Piggy Smart. I'll stop with the wise advice — but don't forget to carry first aid stuff with you when out on a shoot, please.
