Dynamic adjustment of image exposure rate with tracking bar using the the gamma function
As can be seen in the graph of the gamma function, when R>1, the curve is below R=1 and the value of the color space decreases, making the image less bright, becoming an image of little exposure. When 0<R<1, the curve is above R=1 and the value of the color space increases. Macroscopic performance is the increase in image brightness, becoming an image of a lot of exposure.

- 1: Put the images to transform in the folder /img_in/
- 2: In the top you can see a track bar, the value of the track bar is R/0,01
| R | Track bar |
|---|---|
| 1 | 100 |
| 0,5 | 50 |
| 1,5 | 150 |
