What is 48 bit color depth?
When you scan in color, Colortrac wide format scanners scan in 48-bit color. This means that they capture trillions of colors. These trillions of colors are then reduced down to “the best” 16.7 million colors to create a 24-bit color image, or to 256 colors to create an 8-bit color image.
What color bit should I use in Photoshop?
1 Correct answer. Use 8-bit. You could start out in 16-bit if you are doing heavy editing to photographic images, and convert to 8-bit when you’re done. 8-bit files have 256 levels (shades of color) per channel, whereas 16-bit has 65,536 levels, which gives you editing headroom.
How many bits is RGB Photoshop?
Photography software (such as Photoshop and Lightroom) refer to the number of bits per channel. So 8-bits means 8-bits per channel. Which means that an 8-bit RGB image in Photoshop will have a total of 24-bits per pixel (8 for red, 8 for green, and 8 for blue).
Can a JPEG be 48 bit color?
If you are saving your scans a JPEGs, you won’t be able to use 48 bits. Remember, JPEGs only use 8 bits per channel (8 x 3 = 24 bit colour).
Should I scan 24-bit or 48 bit?
24-bit scans are 8-bits each of the three R, G, and B colors and the image is almost always saved as a sRGB JPG. 48-bit scans are 16-bit RGB color and usually saved as TIFFs. In other words, RAW quality.
Should I scan 24-bit or 48 bit color?
Because 48 bit scans are larger in file size, you have a lot more digital information to work with. So if you’re doing any editing for magazines, print ads, movies, it’s best to work with 48 bit TIFF or RAW scans.
Should I scan 48 bit color?
48-bit scans are 16-bit RGB color and usually saved as TIFFs. In other words, RAW quality. If possible specify the ProPhoto color space for your 48-bit scans, but if that isn’t possible use the aRGB color space. You want to capture as much color information as possible.
What is the difference between 24 and 48 bit color?
It is simple. 24-bit scans are 8-bits each of the three R, G, and B colors and the image is almost always saved as a sRGB JPG. 48-bit scans are 16-bit RGB color and usually saved as TIFFs. In other words, RAW quality.
