how can you use photoshop? i'm trying to make clearer pics from the dvd's but i can't on photo editor
There is only so much clearing you can do. If you take a small pic and enlarge it there won't be anything you can do. Smaller images only have so many pixels and enlarging them only enlarges that pixel and doesn't add anymore. If that makes sense. I can recommend a Dvd player on your computer such as Power DVD which allows you to grab screens right off them.
If your picture is blurry there are a few things you can try. Duplicate your layer with the render. 1 - Filter - Other - High Pass (around 1.5-2) put this on overlay and merge down. Next Filter - Noise - Median, change this opacity to around 35%, and set this layer to Soft Light and merge down. After this you can sharpen the picture using smart sharpen and adjusting them to your liking. (I'd like to thank the very talented Sigma for teaching me this technique)
I've attached this picture - The Top is the original sig I made blurry intentionally, the bottom I've applied the technique to sharpen. Enjoy
