Safety first



I was at work yesterday, but still not feeling to great. So far today I have just been taking it easy at home. I have been reading a book called RAW 101, about how to improve photos in RAW format. The picture above is a result of me trying to follow the instructions. I still have a lot to learn. Hope you will have a great weekend

What software do you use to open the RAW files?

I have been using one from Canon, but after reading the book I think I am converting to Adobe Camera RAW 4.2. Using image clipping really makes a huge difference

I use Nikon's Capture NX software. I almost never shoot anything but RAW files. With RAW i am in total control.

Same here but I have not used it to it's full potential

It's amazing to which extent you can adjust the picture before it "breaks"

How true :smile:

my husband won't let me take anything in RAW! He doesn't like the memory issue and he's the man here for storing everything... little by little I'm convincing him. There are some of my pictures that I would love to have taken in RAW for future use... How would I 'technically' explain the benes of this to him?

My girlfriend takes ev. in RAW and then comes home and downloads it all on a separate system... I've tried to explain all this, but I have little technical knowledge yet. I'm thinking of taking a photography class... a good place to start.

Asegir, I hope you feel better soon.

These are the benefits:

* Higher image quality. Because all the calculations (such as applying the gamma curve, white balance, brightness, contrast, etc...) used to generate pixel values (in RGB format for most images) are performed in one step on the base data, the resultant pixel values will be more accurate and exhibit less posterization.

* JPEG is a lossy compression format. Raw formats are either uncompressed or use lossless compression, so the maximum amount of image detail is always kept within the RAW file.

* Finer control. Using RAW conversion software allows users to manipulate more parameters (such as lightness, white balance, hue, saturation, etc...) and do so with greater variability. For example, the white point can be set to any value, not just discrete values like "daylight" or "incandescent".

* Camera raw files have 12 or 14 bits of intensity information, not the gamma-compressed 8 bits typically stored in processed TIFF and JPEG files; since the data is not yet rendered and clipped to a color space gamut, more precision may be available in highlights, shadows, and saturated colors.

* The working color space can be set to whatever is desired.

* Different algorithms can be used, not just the one coded into the camera.

One drawback only:

* Memory use

(Benefits taken from Wikipedia. Couldn't have said it better myself)

that's the thing... but, thanks for this.

For me the best argument is that you have full control over the images. + that you can recover a image that does not look to great the first place

appreciate you feedback, Asegir.

misund007 17. November 2008, 00:52

appreciate yours as well, Jill

thanks!
