Why do some cameras take a CF card and others a SD card? Does it have something to do with the performance of the different cards or what? Thank You. :idea:

The CF cards can be faster and/or higher capacity than SD cards.
Currently, both seem to max out at 256GB, but the SD cards are 90MB/s read and 45MB/s write, while the CF cards are about 150MB/s for both read and write.
If a pro sports photographer is shooting with a 15-20mp camera and 10 frame/sec, the raw files are being generated at a rate of about 200MB/s.

So is it safe to say that the CF card is a better performance card? :idea:

I would say that the CF card has slightly more performance potential, which is only realized at the high end. And most of the cameras which still use CF cards are also at the high end, especially of expected data flow rates.
I am curious why you are "rolling your eyes" at this?

I am somewhat of an amateur could you explain Raw and Jpeg does Raw have something to do with touching up your photos with the proper software. Thank You.

You can edit both, but raw files allow for more changes, because it is "starting from scratch". The jpeg started from the same raw data, and then the camera applied basic processing (adjusting for white balance, other color corrections, noise reduction, and sharpening, for example). With a raw file, the computer software will do that.

I hit the wrong smiley faces. I am still learning what these faces mean.

The problem with starting from scratch is, if you don't know how to cook, it's not going to be particularly edible. I shot raw+jpeg for the past 4-5 years, and basically never touched the raw files, certainly not with any success. Last month I heard about DxO Optics Pro here, which seemed to do exactly what I needed, so now I'm going back to some of the better shots and working with the raw files. In most cases, the camera's jpegs are very good, but in some challenging lighting, the raw files give some more room to improve the shot. In those cases, I can't go back and take the shot again, but I can process it differently.

As Mr. Bill would say... Ooooh, Nooooh....
Yes, raw is better. See... I'm learning. :-)

I must say from reading your replies you seem to be a very knowledgeable photographer.

Thanks, I fake it well. ;-)
I've been doing photography since I was a kid. But there are still quite a few things I have learned in the three months I've been on this forum, raw processing being one of them.

Also, me knowing that a 256GB CF card a fast write speed would work better on a Nikon D4S isn't really about knowledge, it's about fantasy. :lol:
