Let's discuss a HUGE project but so useful one!
The main idea is to generate all possible pictures with a specific resolution such as 1080×1920.

Why:

Your first question might be, why the hell should this happen?

Cause it is literally EVERYTHING!!! Everything has happened, Everything that will happen, it can be a huge resource of inspiration, it can be leaked photos, it can be any media that will be released tomorrow, it can be exactly the future. This is "Why".

If we want to generate all 1080p pictures, it will be around

< 1080*1920*255*255*255 = 3.47892351×10¹³ >

, it is noticeable we are facing two different issues:

Time
Size

Therefore i though as the first step , i should use a lower resolution to generate , so i did some research:

○ 352 x 240 (240p)
○ 480 x 360 (360p)
○ 858 x 480 (480p)
○ 1280 x 720 (720p)
○ 1920 x 1080 (1080p)
○ 3860 x 2160 (2160p)

The best choice is 240p. it will be something like:
 

Alright, Let's check a number of possibilities:

240×352×256×256×256 = 1.417339208×10¹²

it is still a lot but with a huge difference in size.
so I had another idea, limiting the range of red/green/blue:

2 Different Ways

Option 1

instead of having (256³)=16777216 options for each pixel , have ((256/8)³)=32768 => we saved 16777216/32768=512 , in other words (240×352×32*32*32)=2768240640 possibilities

How About analysing size and time:

Size:

Each .Jpg format 240p : 51KB (maximum)
Each .Png format 240p : 254KB (maximum)
It is clear we have to use .jpg format.
All possible pictures size will be :

(240×352×32*32*32)*51KB = 141180272640KB or 137871360MB or 134640GB or 131TB

Time:

Each pixel (in a loop not random) takes 0.000000166

Each 240p picture generate takes

(0.000000166*(352*240))+0.08 = 0.09402368

Then for all Possible pictures, it takes

0.01*2768240640= 27682406.4 sec or 461373.4 min or 7689.5 hour or 320.3 days

Option 2

instead of having (256³)=16777216 options for each pixel , have ((256/32)³)=512 => we saved 16777216/512=32768 , in other words (240×352×8*8*8)=43253760 possibilities

How About analysing size and time:

Size:

Each .Jpg format 240p : 51KB (maximum)
Each .Png format 240p : 254KB (maximum)
It is clear we have to use .jpg format.
All possible pictures size will be :

(240×352×8*8*8)*51KB = 2205941760KB or 2154240MB or 2103.7GB or 2.05TB

Time:

Each pixel (in a loop not random) takes 0.000000166

Each 240p picture generate takes

(0.000000166*(352*240))+0.08 = 0.09402368

Then for all Possible pictures, it takes

0.01*43253760= 432537.6 sec or 7208.9 min or 120.1 hour or 5 days

Thanks for your attention, hope you like the idea and I really love to see your ideas to optimize!
