Digital Photography: The RAW vs JPG Debate

If you use a digital camera (I use a Canon EOS Digital Rebel/300D me) and a SLR camera, then it is likely the images in RAW format can record. In general, you should be taking pictures at the highest resolution possible. If you only have a small memory card and are worried that you are only a couple of RAW can take pictures, then it is time to buy a bigger card! [They do not cost much] in those days. You can always downsize an image after it hit, but you can not lead to an enlargement of a small introduction, without artifacts. At least you should take your camera to record images in Hires JPG format but RAW format is even better.

Any type of JPG written to your camera's memory card will be edited in any way. JPGs, by their very nature, lose information in an image. If you repeatedly save a JPG, you will lose more and more in detail, and there appear to display more artifacts. Also, if you have yourDo> camera up to some image processing (eg contast / adjustments) brightness, these are also applied before the camera writes the image to the memory card. In such cases, you could end up with images that are burned out highlights or shadows that are so deep that they are not detailed. Such areas of an image may be irreparable even with people from Adobe Photoshop.

RAW images, on the other side are simply that - raw. What the camera sees is dumped(no editing whatsoever) to the memory card. RAW images contain more information and details and have larger file sizes than similar resolution JPGs. The problem with RAW files is that they do not have the easiest to operate, for example, Windows Explorer can not display RAW files as thumbnails so if you rename your image files with meaningful names, you will not know what the pictures are when you return to them some months to come later.

This is where software like RawShooter Essentials [http://www.pixmantec.com/index2.html] (RSE) comes in. This software can import digital photographers of all, view, edit and convert large batches of RAW files (to TIF files). RSE is currently free - it will not be too long - so grab a copy now. After he uses it (I can not connect to the company to produce it) have, I can say that it makes working with RAW files is a breeze, much easier than using the software that came my> Canon EOS Digital Rebel.

With your converted RAW files, you have total control over what manipulations are carried out to produce the final image, using packages such as Adobe Photoshop, Adobe Elements or Paint Shop Pro. The better RAW conversion packages also basic contrast, brightness and color management controls, so you may not even be a separate image editing package. Some also offer tools to compensate for over-or underexposedImages.

By shooting RAW images, give yourself complete control over color and exposure, and it's you, not the camera to them to decide what adjustments are applied to the tones and contrast of the original scene to be reproduced. Can also maximize the quality of your final image for whatever output is desired, whether the print on a monitor, like an inkjet printer or a digital photo lab for printing.

Various RAW conversion software is available (IRawShooter essentials mentioned above) so that you edit the digital images in highest possible quality. "Capture One and BreezeBrowser" are both highly regarded, even if you pay for them. A demo version of Capture One is available, so you can try before you buy.

Probably like you, I shot all my photos in JPEG mode ceases, until I have switched to the recording of my pictures in RAW mode. Yes, I had to buy a larger capacity memory card, but also 1Gb cards are prettycheap these days, and) with image files, which is about 6Mb a piece that lets me record well over 200 still images on the card - it is more than 6 rolls of 35mm film equivalent (at 36 frames per roll!

So if you're not already recording in RAW mode, make the switch today, and the full creative control over your photos.

Shortly after I had finished this book, I looked forward to the websites of professional photographers, digital cameras to see whether what they had been usingsay about RAW vs. JPG. What I learned surprised me. A whole series of them shoot in JPG mode as RAW. The reason for this is the time. Experts expect that "the image in the camera using compositional techniques, filters, and the knowledge of their subject and they simply do not have the time to obtain images in order to manipulate a desired result. Such a time would cost them money by the time it is from being out there to photograph and earn a living.

The amateur photographeris a luxury item. Our livelihood does not depend on our results, and if a photo is not quite up to spec. we have the time to optimize them and to bring their hidden places of interest, instead of throwing garbage and a shift to the next image. The lesson to learn is that we should always try the best picture quality on the day with the camera is not too lazy and careless assumption can always be adjusted to get images that are cut and processed when we get home.Post-processing of photos should be about making good pictures even better than one way or the bad pictures just acceptable.
