Thank you in advance for your help. What should be the file size to choose to transfer a RAW picture ( export ) from Aperture 3 to the net / e-mail ? What should be the file format as well ( JPEG, TIFF, etc )? The reason why I ask those questions is because what I do is this : - Process my RAW picture in Aperture 3 - File / Export to my folder located in my profile ( finder ). Here, the computer ask me the file format to convert to, and so far, I have been choosing JPEG medium. What file format should be the best in this case ? JPEG or TIFF and what size ? One of the pictures that I processed today, was a bit blurry when I posted in my portfolio at Photo net so I deleted it because in my computer was perfectly sharp. Don't know if the picture degrade its resolution when it is converted to JPEG or TIFF, is that possible ? What is the best / recommended file format when converting from RAW so the resolution / sharpness of the master / original picture will not be lost or less affected ? Can you help please ? Am I doing the right process or is there any other that I unaware of ?
