since i bought my 20D i just forgot about shooting in jpeg, so now everything i shoot is raw, since i think i have more manipulation on the photo, i can arrange things better. Like for example i shot something and it got a little bit brighter and no many contrast, when i get to the computer i arrange that in the canon program instead of doing it in jpeg. It doesn't ruin the photo so much, with this i mean you don't lose so many information and you can always go back...
I don't know if made myself clear...
But more resumed shoot RAW its much better. :)

Thanks for the reply with the ISBN of the Real World Camera Raw book. I don't know why the link kept showing that the book wasn't found, but now I've got it right - and ordered it!

I always (well, always since I got my first dSLR at Christmas :-) shoot raw and find Photoshop raw pretty easy to work with, but it will be nice to get an actual book about it to check out what I really should be doing.

Well done, puzzled. You are going to learn so much from this book. Enjoy.

Well,

I took everyone's advice and, of coure, you are all right! Raw mode IS much better. I was taking pictures of icicles, and they looked completly different in RAW than in JPeg. I also like that in my CS program, when I get ready to open a RAW image, it lets me choose different "lighting" situations. My icicle picture turned out great changing the white balance choice to tungsten. I will post it!

Never mind, I thought you were trying to post from a DPC photo.

Before I purchased my C5050z I read from a lot of people that it was prone to noise and to get around this take your sharpness setting down one to 2 clicks. I'm not sure if the 5060 lets you do that but I have not ever had a problem with noise, especially in raw format (plus is CS you can change the raw sharpness some)

Good luck.

I know JPEG is condensed, and TIFF is bigger, but what is RAW anyway and what is the benefit of it? Also anyone have a link on "understanding and using the histogram?" Thanks

I know you've gotten a lot of info about it but I had to add my two cents worth. Raw is your digital negative, it allows you to "fix" (usually my case) or change your shot without a lot of work. There is the speed and size issue with some of the cameras but it is very much needed with certain photos.

Another way to think of raw is its name (Raw isn't an acronym like some people think). It is a raw image, like a steak or egg is raw before being cooked. Think of the conversion from RAW as your cooked to order meal. And your JPG as the sandwich you get from a vending machine...ewwww :(

That's a more dramatic statement then the situation is. It's true if you keep opening and resaving an image you only have a jpeg of you will get successive degeneration, but that's not to say that you can't do something about it either. If you were going to be doing that anyway, just like the raw, you never save over the original, and also for intermediate work you just save in a different non-lossy format(PNG/TIFF/PSD etc) until you are done making changes, so you can minimize picture degredation from successive re-saves. The lower bit depth and detail lost from the original compression pass are far more of an issue then successive writes should be.

Which brings me to my question. I saw some people saying how the RAW formats preserve the 36 bit data coming from the sensor. How does one view 36 bit data with any kind of perceptible difference on hardware that's only capable of 32 bits of color information? Is the extra bit depth color information or something else like alpha?

Hmm I've never really given this enough thought, but is RAW actually 36 bit color, or is it something else plus alpha? Like 32 bit color is really 24bit + an alpha layer.

Anyway, whagerbaumer, the difference between 36bit and 32bit color should be in the range of 64,424,509,440 per pixel, not 4096. You didn't quite put the bits together all the way....

Are you using Memory Stick Pro on the F828? I normally use a Memory Stick Pro, and it takes about 11 seconds for a RAW shot. If I use an older non-Pro Memory Stick, it takes 30 seconds for a RAW shot.

My partner has a CF card that takes about the same length of time as the Memory Stick Pro. (I know that CF cards can have different speeds as well--I think his is 12X.)

Edit: By the way, I also bought Photoshop Elements 3 thanks to your earlier F828 thread, and I am quite happy with it... If only Adobe gave commissions. :)

Yup I got a Memory Stick Pro, it is a bit faster then my CF card at saving raw so I do tend to use it when shooting raw. Mainly I got it for HQ video. Still 11 seconds is a long time to wait before you can take the next photo. My wife has a 20D, no waiting there even in raw.
