1 Bit vs 8 Bit vs 16 Bit vs 32 Bit in Photoshop – Bit Depth Explained in Easy Way
In this video we will be seeing what is bit-depth in Photoshop by understanding the difference between 1 Bit vs 8 Bit vs 16 Bit vs 32 Bit. Understanding this is crucial if you want to perform extreme edits in Photoshop, because working in the wrong bit depth can result in color banding and artifacts.
We will also be seeing how many colors are there in each bit-depth mode by seeing how exactly a pixel gets derives its color in Photoshop using binary code.

Video Summary
In this tutorial, Kush Sharma explains the concept of Bit Depth in Photoshop and how it affects color transitions and image quality during editing.
Key Concepts and Takeaways
- Understanding Bit Depth [04:15]: Bit depth refers to the amount of color information stored in each pixel. Higher bit depth allows for smoother color changes and prevents “banding” or artifacts.
- The “Banding” Problem [02:48]: In an 8-bit image, extreme color shifts (like changing a blue dress to orange) often result in pixelated, blocky artifacts because there aren’t enough “shades” to create a smooth gradient.
- Bits per Channel [18:08]: * 8-bit: Offers 256 shades per RGB channel, totaling ~16.7 million colors.
- 16-bit: Offers 65,536 shades per channel, totaling over 281 trillion possible color variations [21:15].
- The 1-Bit Experiment [14:49]: Converting an image to 1-bit (Bitmap) demonstrates that each pixel can only be strictly black (0) or white (1), losing all tonal variation [15:13].
- Practical Recommendations [23:35]:
- Bit Depth vs. Color Theory [25:12]: While high bit depth helps, achieving a perfect edit also requires an understanding of color theory to handle complex transitions effectively.
