Last minute changes are necessary sometimes

Live from the WeAreDevelopers Congress in Berlin, where we will be presenting tomorrow.

Our session will take place at a stage called Airstream, which is located outside. We have a large TV screen for our slides and demos, but being outside introduces natural light that you wouldn't have in a dark room.

Why is this such a big deal?

Contrast.

Our presentation features a black background with thin dark grey lines to illustrate one of the concepts we're discussing. However, when outside and exposed to natural light, these lines become invisible. Therefore, adjustments are necessary, such as using a lighter shade of grey for the lines.

Conducting tech checks or arriving early at your presentation location is important. Very, very important. Don't skip it.
