Would love to help with that. One of my favorite subjects.
To get the best of your event photographer is to understand what you need to do the images.
And before that, you need to ask one simple question. What do I need to improve, or what do I need help with.
You see, images are magical. They can do a lot of things.
Do you need improved user experience? Then you need live images and some type of activation.
Do you need social media engagement? Same thing, only more live images & good targeting.
Do you need separate content for customers/visitors, speakers, Press, in-house ... and so on?
Do you need just a few images a couple of days later or a week later? Then you just need somebody you can trust, and that is it.
I think asking those questions first can give you not just the brief, but also a description of the correct photographer you need.
It can also help with the budget. Because if you actually improve some of all of the above, RoI is raising, so the added value is way bigger.
The point here is that a good brief is not what photographers do we like, and what does he need to shoot? It needs to start what do we need to add value to the event.
Keep in mind that the average lifespan of an image online (social-media especially) is 2.5 seconds!!!
So you might need the most amazing photographer that can produce the most amazing 20 images from the event, that will go through 3 weeks of post processing! Because that is what is going to increase your RoI and get you more sponsors. In the same time, you might need a small photo-booth
I think photography is way underrated because we are very conservatory with it. Because we got used to having something exactly like that. The secret is how you use the images, not the photographer(s).
Verry happy to talk more about the subject
