The size of the electronic version of the photo exhibition is required to be more than 2M, and mine is only 90KB. What if it's not enough?

The reason why such a large file is needed is for post-processing and making larger photos. Explain that this competition needs a certain degree of professionalism.

If your photo is not too bad, you can make up for it by stretching it with software, but yours is too bad.

Is this original photo you took very small? If so, it means that your photos are too small and the resolution can't meet their requirements. Even if you stretch hard, it will be blurred, so it will be brushed off when you participate in the competition. Let's give up the game.

Next time, use a camera with higher pixels. It is estimated that it takes more than 8 million pixels to reach this size.
