- The last editing technique I'd like to share with you…is extended development.…You use it to subtly increase the density…in the highlight values.…In other words, when I say increase the density,…what we want to do is just add a little bit more tone…in the brightest of highlights.…Comparable technique would be in your levels adjustment,…grabbing the top slider and moving it over…or maybe five points just to bring that…tiniest bit of detail into the highlights.…If you're working with a RAW file,…think of this as a way to do maybe some highlight recovery…if your negative is a little overexposed.…
You can see the image we picked.…Once again, we're back at the Mammoth Hot Springs…in Yellowstone National Park.…These bromide deposits are blindingly white.…Capturing them was a real challenge.…We had to do some exposure adjustment.…Typically, when you're trying to capture…highlight values like this,…you want to overexpose to build up density on the negatives.…In doing our overexposure,…I think we created a little halation…
First Konrad provides a tour of his own darkroom space, and introduces the key ingredients that dictate how pictures print: paper, exposure, and contrast. He checks a series of images by developing initial test prints, and then explores options for refining the images in the darkroom via cropping, burning and dodging, and adjustments to the development time. When he's finished making prints, Konrad shows how to clean up the darkroom and introduces different paper choices and resources for black-and-white film photographers to explore.
