Hi gang, When converting a JPEG file to PSD format, the size grows considerably. For example, a 1.5mb file from my digicam becomes almost 10mb in size. I don't object to that, but was just wondering about the mechanics of how that happens within PS. Anybody know? Is it interpolated upwards, or perhaps the information is already somewhere in the JPEG file? I believe it also happens when converting a JPEG to a TIFF. Is that done in the same manner as the conversion to PSD?
Now, the real question is this: is any information lost or created in such conversions that it degrades the image making it better to shoot in TIFF format, or is the image information only improved and not harmed in any way by making the change? shel
