For my work rather important. I've been taking series of pictures of dynamic events and after about four pictures the camera needs to unload the buffer into the card.

RAW should be better than TIFF. The file sizes are around 2/3rds the size of a TIFF on the D.

That's a PS issue, or more likely a PSP issue. My offhand guess is that PSP is not honouring the embedded colour profile. Convert them to sRGB and you should be good to go.

PEF doesn't have a colourspace per se. The convention holds from the JPEG and TIFF's and also affects the embedded JPEG as well as the default conversion settings, but as the PEF is raw sensor data it can't have a colourspace. I use ProPhotoRGB for my PEF conversion space just fine. -Adam Rob Studdert wrote: On 10 Nov 2005 at 9:30, William Robb wrote: I just checked the Corel website regarding this.

Re: Speed of memory cards...
Moderately fast cards will be beneficial, although the camera will not take full advantage of the fastest cards available. You will still see a noticable boost in a card reader with the fastest cards, which aids in getting images off the camera (use a card reader, the in-camera USB is slow and drains batteries). -Adam Albano Garcia wrote: ok, then again, very intersting talk, but my question remians: it's important the speed of the card? extra fast cards are worth it?

Re: Speed of memory cards...
Making average of slightly different opinions, I believe cards faster than 60-66x are just more expensive, while they add nothing to camera write/read speed. However, they will be faster while downloading via USB2.0 reader. This doesn't interest me enough, hence I stick to 60-66x.
