Digital Camera PrintersWho doesn't love digital camera? I know for a fact that I surly do. I use my digital camera to take a picture of the landscape, with dark skies and fluffy white clouds. After you have that photo, how do you give the photo to someone after it's done? Digital camera printers will give you instantaneous results. If you need black-and-white images, some cameras do indeed have a black and white setting that might be worth a try, but I'm looking for getting the very best out of my camera and want to use 'raw' images, just the same as I would with color. The black and white setting gives you 8 bit black and white JPEG images. If you shoot raw and JPEG at the same time you'll find that the raw files are still in color.
A brother color laser printer will allow you to get a full range of colors that more closely match what Photoshop will put out. An 11x17 color laser printer will be able to print even the biggest photo that comes from a 10 Mega-pixel camera. An HP color laser printer is probably one of the best laser printers, although brother printer cartridges cost less. I'm going to be looking at converting the raw files to color and then to black and white. The examples all used Photoshop CS for raw conversion and subsequent image processing. You could use other raw converters and photo editors just as well. In my own work I often apply some fairly hefty curves and adjustments to my black and white images. Posterization can be a real problem if you are working with 8-bit images (such as from JPEGs). One way to reduce the risk is to work in 16-bit where you have more data to play with the differing chemistry and manufacturing processes adopted by various manufacturers resulted in different films producing subtly different renditions of the same scene. It was soon discovered that using colored filters in front of the lens also altered the image. If you are going to print out those photos, digital camera printers are the fastest way to go; and they will reproduce the colors you see in Photoshop. When you're trying to emphasize colors in a photo, a red filter cuts out some of the blue light from the sky while still letting through the red component of the white light reflected from clouds. This results in darker skies, which emphasize the clouds. More complex mixtures of colors, such as flowering plants and skin tones, would all look slightly different on different films and with different filters. For all of the conversion techniques I'm going to describe, I'll assume that you have a well-exposed raw file with very little clipping of highlights. By all means experiment with any pictures you want, but starting with good color originals allows you to see the effects of different conversion processes more easily. Digital cameras are thought of as recording scenes in pixels of red, green, and blue. Actually each pixel is sensitive to a range of colors and has a little colored filter in front, so it is more accurate to think of each one contributing to a grayscale image (channel) representing values of mostly red, mostly green and mostly blue. Digital camera printers will allow you to print all those colors in full brilliance. This gives one of the simplest conversion techniques, just pick one of the channels - it's already in black and white. If you want to use the red channel, delete the green and blue channels and change the image mode to 'Grayscale'. Very simple, but you are throwing away a lot of your picture information, and for the best quality, that's not really what we want. Digital camera printers are good at printing both black-and-white and color prints. I hope this article helped you get better quality prints so they would print on your digital printer. |
