With 2.8 coming out and I see numerous people are saying make sure you use 16 bit color codes... and I see so many different texture formats..... can someone remind me which are getter png, jpg, tif, tga, etc and how do you make sure you are using 16 bit color code etc.
Thank you
PNG is a lossless compression file, meaning the file size is less, but the quality of the image is not lost. It also supports an alpha channel. JPEG is a lossy compression file, meaning the file is compressed but the image loses some quality. It does not support an alpha channel. The other file extensions are either lossless or lossy compression types.
Here's a Wikipedia entry that talks about different image extensions.
16 bit color is in reference to how many bits are available for the red, green, and blue channel. With more bits, you have more data you can store, which leads to a greater range of colors you can see. This can affect things like normal maps, displacement maps, etc. and how smooth those maps can be.
Here's an article that goes into more depth.
