Answer 1

hi....
RAW images contain unprocessed image data direct from the camera's sensor. In order to convert this data into more usable formats((jpeg)) you must first process the data on your computer with a specific software((i use the the image data convertor which comes with my camera and photo shop CS2)).
here u can adjust every RAW property u can think of..from white balance to exposure to sharpness and color,,if u like to play with tone curves ....reduce the noise,,add some affects to ur image ..
all this can be done with RAW image via a special software.
it'salmost like u get a second chance to take ur photo.
but u have to note that it's alot larger than their jpeg equivalents ...so it will take up quite a bit of space on ur memory card.

Raw is the data strait from the sensor after it has been De-mosaiced and digitized in the A to D (analogue to digital) converter, also the EXIF data is added and some other data such as the number of pixels across and the number of pixels down and codes that tell the computer that the data (which is just a list of several million numbers) is to be treated as an image. It's not true to say that ALL Raw formats are compressed, most are, but DNG files are not, they will always be the same, larger, size no matter what the image content. The advantage of DNG files (if your camera such as Pentax can store in that format,) is that any version of Photoshop can open them from CS2 and above. All this means that you have ALL the data captured by the sensor is available and stored in a 12bit or 14bit format. Every time you add a bit you double the accuracy of the data. Jpeg on the other hand is only an 8bit format this means that, taking the Red channel as an example every shade of Red from the palest Pink to the deepest Crimson has to be one of only 256 values, where in the 12bit format it can be one of 8095 values, in 14bit it cam be any of 16,535 values so will be recorded more accurately. Worse than that whatever doesn't fit inside the 8bit 'container' that is the file will be 'dumped', gone forever. The compression used by Jpeg to make the file smaller can also add artefact's (speckles) to the image. The final advantage is that editing will always degrade a Jpeg, all Jpeg files are full, there is no 'headroom', so if, in the course of editing your picture, you move some of the data outside of this small 'container' then they too will be 'dumped' which can (and does) lead to banding in smooth tones and other horrors. There is always room in a 12bit file, even more in the 14bit so any editing, even extreme, will be saved with no losses whatsoever. So Raw saves data more accurately, it saves ALL of it and you can use extreme editing without loss. Chris

Actually, RAW is available on some higher end consumer digicams. My Canon G6 has RAW, (but not the G7, alas!)
I think maybe Oly used to have a model or two that did RAW as well. Check your manual to be sure yours does not.

Answer 8

I have the previous end model of this camera, the SP-310, so I can assure all of you that it does, in fact, shoot in RAW (.ORF format). With that said, RAW format is essentially all the data that the camera sees when you press the shutter, but unprocessed. With typical Point and Shoot cameras, photos are saved as JPEG format. When you hit the shutter, the camera processes the data viewed on the sensor, and applies preset sharpening, color adjustments, and white balance settings to this data and outputs it to a simple JPEG file. With RAW, you can make all these changes yourself, without the camera doing the work, and compressing the image beforehand.

The camera should come with software to read the ORF format, but if you have Adobe Photoshop, you can download Adobe Camera Raw to do RAW processing directly in Photoshop (which is what I use, personally).

Here's an article for you. Be sure to note that it is 3 pages long and not just one.

Kyrios, http://www.dpreview.com/reviews/specs/Olympus/oly_sp510uz.asp says that this camera IS capable of shooting in RAW.

Answer 10

Raw is an uncompressed photos and only available to shoot with an SLR or limited amounts on non-SLR cameras. Unless you are doing very technical or complex photo editing, you need not worry about having the raw file.

By the way, your camera isn't capable of producing a raw file. Don't worry about it.

BTW: By someone;'s thumbs down response to my reply, I can see they don't know their azz from a hole in their head.
