Some basics in digital imaging

May 1, Year 2012. Be aware of that this page is not updated frequently any more. Sorry!


digitala bilder As we are dealing with colours - you monitor does not necessarily show colours accurately without being calibrated, and there are many issues involved in coordinating what you see on the monitor with how it prints. Some of my other favourite places I have learned a lot about Managing Color in Photoshop 6 and 7, and ColorSync & ICC-based color management are from the following sites

  • A common question is: Could anyone tell me what is the best way to make the colours in my monitor (using PS CS2) to look exactly as they are printed? (or the other way around ;)
    One answer can be: You can try and make these corrections visually, without a spider, but it's difficult. That's what Adobe Gamma tries to do. It is a basic monitor calibration utility, intended to help you match what you see on-screen with your prints. In order for it to really help, you need to go to your control panel and go through the calibration process. So try using Adobe Gamma first and see if it improves on what you have now. If not, a spider is the only real solution. When you create profiles with a spider they change your screen on boot-up. The correction is applied to all programs. There are differences between how Macs and PCs handle this, also depending on the version of the operating system used, but this is true generally according to Michael Reichmann. A Swedish evaluation of the Colorvision Spyder can be found here!

  • Monitor Calibration and Profiling by Ethan Hansen He is an active and valuable contributor on digital photography forums. There some good stuff on his site Dry Creek Photo.
    If you can not trust the colours displayed on your monitor, all other color management is a waste of time. Calibrating and profiling your monitor should, therefore, be your first priority. Luckily, it is the easiest part of the image capture, editing, and printing system to profile. The cost to do this ranges from free to expensive. If color accuracy and the ability to match your prints to your monitor are important to you, a decent hardware calibration system is essential. With a little work you can get good color from your monitor. If digital photography is your business, or you simply want the best colours you can get, the expense of a high quality calibration system is more than justified.
    This site has also links to some downloadable files in Lab format containing images of the Gretag Macbeth ColorChecker card. If you view the Lab file in Photoshop 6 or 7, and compare the on-screen image to a GM card viewed under a D50 lamp or similar, then you will get an idea of how good your monitor profile is.

  • Out of Gamut: Don't Underestimate Photoshop's Auto Color by Bruce Fraser Imaging professionals tend to veer away from Photoshop's overly simplistic automatic color-correction tools. But version 7's Auto Color mode is a horse of a different color, if you know how to use it. Color guru Bruce Fraser shows you how.

Photoshop plugins Digital Imaging Help is a good resource. Digital imaging refers to the act of creating digital images, or photographs, through the use of editing and computer image editing software. Digital imaging involves a number of activities, which include the processing of the images, as well as compression, printing, storage, and display. Mostly, cameras or other photographic devices are used to capture a physical scene and transform it into a digital image. The image can also be produced from an analog image, which may be print, photograph, or photographic film.

Red Eye´s The best red-eye reduction is an external flash. The flash needs to be off-axis from the lens, by "enough". If you used an internal flash and got reflections from the eye which caused "Red Eye's" on your photo, how to get rid of it? If you can include some nearby light, it may not be enough to warrant switching flash off, but it may close down your subjects' irises enough to cure the red eye. This tutorial is one of my own. You can also download this filter plug-in for Photoshop which works fine for me in most cases. Unzip and copy to your Photoshop plug-in folder.
