Be the first to post for 'What Is A Digital Image'!

If you’re reading this, there probably aren’t very many posts yet. But don’t worry, you can be the first! Either create a new post or just reply to this one to say ‘hi’.

I chose one of my images created previously in the course.
House%201%20Coloured

House%201bit 1bit

House%202bit 2bit

House%203bit 3bit

House%204bit 4bit

House%208bit 8bit presumably (original in greyscale mode)

It’s interesting to see how the changes between 3, 4 and 8bit are not that significant and 1bit and 2bit have major shading differences. I guess it all comes down to the values becoming closer and closer to the original. Granted the image was only 32x32 originally, so there would be more changes to see in images with higher resolutions and shade differences. Fascinating :slight_smile:

hi

Original Grayscale Image

3 Bit

4 Bit

I think it depends also strongly on DPI en the physical size of the image.
Like an e-reader. It’s only using one bit images (black/white dots), but it looks like it’s showing a grayscale image.
