Pro Tips
8-bit images can display 16.7 million colors. 10-bit images can display over 1 billion colors, reducing banding.
PNG is a lossless compression format, usually achieving 1.5:1 to 3:1 ratios.
JPEG is lossy and can achieve 10:1 or 20:1 ratios with minimal visual impact.
High megapixels are great for cropping but fill up SD cards and hard drives much faster.
