in RAW
by Kermit Nourse Most digital cameras today come with the option to take pictures in RAW or JPEG format. What’s the difference you ask? Well, for those who want to take the best quality photos possible, RAW is the best option. RAW is a digital image negative developed by Adobe Systems while JPEG is a compression of a digital file developed by the Joint Photographers Expert Group. Even though JPEG does a good job it is inferior to a RAW image simply because the data has been compressed. Compression is not always good and you will notice the difference. RAW has some disadvantages. For example, you can’t do anything with a RAW file, you can’t print it or send it over the Internet. They just float around in limbo inside your computer taking up space. And, in addition to that, it will cut the amount of pictures you will be able to take on your cameras memory chip to about half. A RAW file size is about twice that of a JPEG image, and that is where the beauty of RAW files comes to fruition. RAW has more details. Why use RAW then, you might ask? Because if you edit a photo in RAW you have twice as much information to work with thereby producing a much better photo! But how can we edit in RAW? Chances are your camera came with software to at least do some rudimentary editing in RAW. Don't have that either? There is some good news. Free downloads are available for use on a trial basis, and by the time you finish trying out all of these you will be an expert in editing in RAW. They are as follows, and available on the company’s website: Nikon Capture NX2 60 day trial Apple Aperture 2 30 day trial (for Macintosh Lovers) Adobe Lightroom 30 day trial Adobe Photoshop 30 day trial Adobe Photoshop Elements 30 day trial I use Nikon Capture NX2 and have found it to be excellent for editing RAW images. It is also one of the least expensive RAW editing software packages on the market. Well with that I wish you good hunting with your digital camera. After the files have been edited save them as TIFF (which is another image format ) or JPEG. The result? A much better photo! Next issue we will talk about taking photos in black and white or how to desaturate color photos correctly. The photo below, of Señor Lucas Cerrud, was taken in RAW color and then edited to black and white.
Editor's note: Alas, online there is a big tradeoff between photographic quality on the one hand, and time of downloading and bandwidth considerations on the other. Generally Internet photos are at 72 pixels per inch resolution and have to fit within allotted space. But compare this compressed for online usage version of the photo with the photo before being shoehorned into our space and resolution restrictions.
