Did photos exist in the 1800s?
Throughout the 18th century, scientists played with materials that caused the light to stick, creating a still image. However, it wasn’t until the 19th century that a breakthrough occurred. The world’s earliest successful photograph was taken by French inventor Joseph Nicéphore Niépce in 1826.

How do I know the KB size of a photo?
How to calculate image size – Quick summary
- Multiply the width and height of the image, in pixels, to get the total pixel count.
- Multiply the total pixel count by 3 to get the image size in bytes.
- Divide the number of bytes by 1024 to get the image size in kilobytes.
How many KB is a 4×6 photo?
So, for a 4×6 you need 4 inches x 300 PPI = 1200 pixels for the short side and 6 inches x 300 PPI = 1800 for the long side. In other words, there is no improvement in print quality over 1200×1800 pixels. However, you also specify 256 kb (which presumably is the file size) and 10 MP.
