HDR imaging represents a radical departure from traditional forms of photography. HDR (high dynamic range) images hold more luminosity than conventional cameras can record and potentially more than the human eye can see (at any one given time). Read More...
Double exposure gives you two times the image information to use in a final image
This is the third in a series of “R/Evolution” columns on Extended Dynamic Range (XDR). Extending dynamic range has become increasingly mainstream for professional photographers as software has become more powerful and new techniques have been unveiled. Read More...
Extend the dynamic range through this processing technique
Reproducing the full range of tones or brightness values seen by the human eye is one of the most fundamental challenges in photography. Capture, display and print technologies are all limited when compared to the ability of the human eye to see a wide dynamic range. Recent advances in technology enable you to exceed these limitations. Read More...
Extending the dynamic range in your images is possible with sound technique and a little software magic
Reproducing the full range of tones or brightness values seen by the human eye is one of the most fundamental challenges in photography. Capture, display and print technologies are all limited when compared to the ability of the human eye to see a wide dynamic range. They're all advancing. As they advance, our methods for addressing this fundamental challenge advance with them. Read More...
In this first in a series of columns about digital black-and-white, we explore some of the fundamentals
Prior to the 21st century, black-and-white photographers developed a heightened sensitivity to the direction and intensity of light, a given relationship between highlights and shadows, largely discounting the appearance of hue and saturation unless able and willing to use color filtration during exposure. These perceptual skills are all very important for 21st century digital black-and-white photographers. But, today, because you can make any hue light or dark, globally or locally, and you can make more dramatic changes to more saturated hues, hue and saturation need to be factored in rather than factored out.
Strategies for selectively lightening and darkening an image
This is the first iteration of a new Digital Photo Pro column from John Paul Caponigro, a master photographer and artist who teaches workshops, writes books and lectures on Photoshop technique. In each installment of (R)evolution, we'll examine a technique for improving your photographs. By focusing on a single problem in each column, we hope to show you the depth and power of some of the tools at your disposal in Photoshop.
Mastering this tool will help to ensure that you have continuous tones in your images
Smooth transitions. They're the essence of continuous-tone images. In most cases, you want to preserve them. On occasion, you want to modify them. Sometimes, you want to create them. While gradients can be extremely complex and yield highly sophisticated results, once the basic principle behind them is firmly grasped, they're simple to create and use. Using the Gradient tool, a gradient is created between the start (where you click first) and end points (where you drag to). The start and end points may be placed anywhere on the canvas. Gradients can be drawn for any length at any angle.
Take control of the contrast in your images with precision using these Photoshop controls
The relationship between highlights and shadows is a critical aspect of any image. Photographers have been trained to become highly sensitized to these relationships. Today, we have more control and greater precision than ever before over these key visual elements using the digital darkroom. In Photoshop, the type of adjustment chosen will provide very specific control. The specificity of an adjustment can be further refined by using a mask. One type of mask yields extreme precision and is derived directly from the light and dark relationships within an image—a luminance or contrast mask.
Use this powerful tool to affect precise areas of your image smoothly
Digital imaging offers the ability to define complex contours efficiently and precisely, enabling users to affect an image in very specific areas. What was once tedious and challenging is now quick and easy. Once you learn a few essential selection and masking techniques, few contours will elude your grasp. Before I continue, let me caution you against defining contours too precisely. Remember, contours in continuous-tone images are often quite soft. What's more, many times photographers simply need to define broad areas to work smooth transitions into surrounding areas. Just because you can define contours precisely doesn't mean you should, but it's advantageous to have the option when you need to.
