Some new pics to crit...

:dooby:

 

I can fit around 28 raw photos on a 512MB card.

The camera is 8MP

 

Okay! I guess I'm gonna have to upgrade to a 2Gb card...

 

my 1GB card for the 80Mpx 20D will take 107 RAW. Its a Sandisk Extreme III which is recommended for the high fps in case you want to shoot the action of a hippo charging at you

 

Hi, i cant see no photos? Are they removed? Please.. Post them again.

 

just got a Sandisk 4GB Extreme IV CF card. On a EOS 20D it can take 466 RAW shots at ISO100. I found out that this projected number will drop if you set to higher ISO settings. At ISO800 it goes to around 360.

 

Interesting. I wonder if that's from the data overhead of all the noise in the image...

 

yes with more noise you expect to less compression.

 

Wait, RAW? That does not make sense....

Unless you are shooting RAW+Jpeg. Then perhaps the JPEG size will change for different ISO. That at least makes a bit more sense. RAW is the raw data from the camera pixels that wont change with different ISOs.

 

why not? RAW is lossless compressed.

 

You are absolutely correct! For some reason I assumed it was not compressed. A quick search shows that I was wrong... BTW I saw a few links that suggest that Nikon is doing quantisation of data before saving a compressed RAW. Strange.

Thanks for clearing that up
