this is the rules: Image File Format: The image must be in the Joint Photographic Experts Group (JPEG) format. Image File Size: The maximum image file size is 240 kilobytes (240 KB). Image Resolution: 600 pixels high by 600 pixels wide. Image Color Depth: 24-bit color [Note: Color photographs are required. Black and white, monochrome images (2-bit color depth), 8-bit color, or 8-bit grayscale will not be accepted.] but in my photoshop i have only 8-bit and 16-bit. (see the attachment) so How can i create 24-bit JPEG file for DV-Lottery? its very immediately, plz.
oh that's going to be tough! the Joint Photographics Expert Group was a committee, they never made a format that complied with their specifications. I hope they'll allow you to use a JFIF, JPEG File Interchange Format image, cause that's the closest implementation to the specification that we have now.
Jpgs by definition(the native files) are already 24 bit: 8bits for Red, 8 bits for Blue, 8 bits for green! I.E. they are 24bit RGB In Photoshop, when you see 8, 16, 32 ---> bits = that is really BITS PER CHANNEL so a 16bit file in photoshop would have 16 bits for R, 16 for B, 16 for G make sense??
