How to Adjust Color Management Settings

How to Adjust Color Management Settings

Color Management is the process of controlling color reproduction through a workflow. There are college-level courses and certification programs on color management and the subject is way too complex to discuss in a single article. The purpose of this article is to make you aware of the process and to understand where color management may be implemented on your computer. Most color management in graphic applications is applied through the use of ICC profiles. An ICC profile is a set of data that characterizes a color device according to standards created by the International Color Consortium (ICC). Profiles contain the color attributes of a unique device and "translate" the differences between the source and target color spaces (to learn more about color, visit the links in Resources below). Profiles can be implemented in a variety of places on your computer system and conflicts between profiles can cause inconsistencies between the color viewed on the monitor and other devices. Here I will outline the steps in order to familiarize you with how color management is implemented on your system.

Instructions

    1
    Adobe Gamma

    Adobe Gamma is an application that is installed automatically on your computer when you install most windows Adobe Imaging Applications. You can locate the Adobe Gamma application under CONTROL PANEL in all Windows computers. It provides an easy way to implement ICC color profiles on your system so that all applications have the same color management. It does not automatically ship with newer Adobe products, but may be downloaded from the Adobe website. To find out how to use Adobe Gamma, see link in Resources below.

    2
    Driver Adjustments

    The next place you should check for color management is in the device driver application. You can find your device driver settings in the CONTROL PANEL under DISPLAY. Click on the SETTINGS tab and ADVANCED to view the device driver settings. Each video card will have different controls. On this device driver I can assign a color profile to the desktop and adjust it, but only after I click the COLOR MANAGEMENT tab and ADD the profile. Since I am using Adobe Gamma to manage my display, I do not have a color profile set here, since it could cause "confusion" and inconsistent color. I would have a profile set here if I was not using Adobe Gamma.

    3
    Device Properties

    Each device may have a separate color profile attached. This profile characterizes the individual device and you may choose to have a profile for each device like a video camera, scanner or digital camera if you find that the device has a particular color characteristic. My QuickCam delivers "warm" tones so I have applied a SRGB color profile to neutralize this tendency.

    4
    Basic Profiles

    You may not know it, but Windows systems come with basic color profiles allowing you to choose a profile for your device. You can also download additional profiles from ICC or manufacturers of your color devices. There are thousands of color profiles. You can also create your own color profiles using a spectrophotometer, but this is only for experienced users with the correct tools.

    5
    Software Adjustments

    Your imaging software may also have the capabilities of applying color profiles. This is the color settings screen form Adobe Photoshop Elements which also allows you to apply a profile to your image. Software programs usually only impact the open image, but make sure you do not apply a conflicting profile to one that may be set up for your operating system. You can use color profiles here to adjust a particular image destined for a targeted device.

    6
    Printer Adjustments

    Finally, you can also attach a color profile to your printer. Windows will automatically choose the best profile, but if you were printing an image for a specific application (e.g. Newspaper) you may want to choose a SWOP or other printer profile. Keep in mind printers operate in a subtractive CMYK color model, unlike your computer screen which is an RGB model. You can change your computer screen to a printer profile to get an idea of how it will look when printed on that device. The bottom line is to keep in mind that color management can be applied at a variety of places in your workflow. Make sure you manage these properly to assure that you will have consistency in capturing, viewing and printing your color images.

How to Use Photography Techniques With Indoor Lighting

How to Use Photography Techniques With Indoor Lighting

Taking pictures is all about light. Unfortunately, indoor lighting creates some unique problems with stark fluorescents that make your model look ten years older or inadequate lighting that results in underexposed images. If you avoid taking pictures inside, a few tips from the pros might change all that.

Instructions

    1

    Use what you have. The common misconception is that you cant get good photographs unless you have expensive lights, reflectors and backgrounds. While these certainly help, you can get good shots without them.

    2

    Use your on-camera flash for snapshots of parties and get-togethers. While a flash isnt optimal for indoor portraits, its good for illuminating the activities.

    3

    Turn on every light in the room before snapping away with your flash to reduce the risk of red-eye syndrome. The flash from your camera in low-lit rooms reflects on the subjects dilated pupils and turns them a demonic red. Increase the lighting in the room before taking the shot.

    4

    Tape a tiny bit of tracing paper over your cameras flash if you cant increase the lighting in the room. This will tone down a harsh flash while still casting filtered light on your subject.

    5

    Bounce your flash for the most flattering people pictures. You can use a professional bounce flash or you can tape a small mirror at a 45-degree angle in front of your cameras regular flash. If you cant find a small mirror, just use the reflective side of an old CD and cut it to fit.

    6

    Take portraits by the window. If you can find a large window where the sun is not shining directly in, have your subject sit beside it where the light gently illuminates one side of their face and use a tripod to take the shot. Turn off your flash and let your cameras automatic exposure do its job.

    7

    Look for reflective objects before taking the shot. Eyeglasses are the biggest culprit when youre using a flash. By turning your subjects head to the side, you can avoid a stark flash reflection.

The Uses of a Pinhole Camera

The Uses of a Pinhole Camera

Pinhole cameras, which are extremely simple cameras that you can even make at home with any light-proof box, have become increasingly popular among modern photographers in recent years. While the pinhole camera, in general, is far more basic than most manufactured cameras, that very simplicity has made it an attractive option for experimental photographers, as it produces sharp still images and allows photographers greater flexibility with the size of negatives and timed photography techniques.

Taking Pictures

    Of course, the primary use of a pinhole camera is simply to take pictures. Pinhole photography, however, has several special characteristics that make its pictures unique, including continuous depth sharpness at all distances and the ability to capture a wider range of frequencies in the electromagnetic spectrum. Unlike conventional cameras that use digital techniques or a series of lenses to capture an image, a pinhole camera simply opens a light-proof box to outside light, exposing film to the direct light produced by an image. Thus, many photographers feel that the images produced by a pinhole camera are closer to the photographed image, unaltered by reflective lenses or digital recording.

Time Exposures

    One of the perceived disadvantages of a pinhole camera, its long exposure time, has actually become an advantage in the hands of experimental photographers. As a pinhole camera does not use lenses to amplify or focus an image onto film, it can take a pinhole camera longer to capture an image, sometimes up to 15 seconds in low light conditions. This forces a photographer to keep the camera still, open and pointed at an image for long periods of time before the image is sharp. Many photographers, nonetheless, have used these long exposure times to play with movement in their photography, recording partial images or blurry sequences of moving objects.

Editing Negatives

    Although most manufactured cameras are assembled to work with a specific type and size of film, the simplicity of pinhole cameras allows a number of film types to be used, particularly in the case of home-made cameras that can be of nearly any size. The increased flexibility pinhole cameras provide with film allows photographers to produce negatives of all types, including very large negatives that are easier to edit or color.
