If a camera only has a iso 1600 capability, how do you push it up to 3200?

Use levels to expand the histogram. Since that increases the noise, almost certainly find the noise level to high to use the image for anything but very small prints and/or small web images.

Just shoot however you want under ISO 1600. Take the image into a photo editor like Photoshop and duplicate the background layer and use the duplicate in "screen mode". Everything will get lighter. If it's still not light enough you can stack layers, making copies of the first duplicate. There are more nuances in doing this, but that's the gist of it.

The best way to do this is to shoot in RAW. RAW gives you two extra stops in either direction. The noise may or may not be objectionable. Certainly pushing it one stop will not significantly increase noise, although at 1600 you have inherent noise anyway.
This is MUCH better than editing later in Photoshop where you are not actually adding an F stop, merely chanbging the existing levels. Dave |
