That sounds incredibly clunky. You would like to make 10,000 individual printouts, and put them together on the floor like a jigsaw puzzel? Is that right?
Would your project allow you to do somethinh like turn on Pixel Grid
Set up a 10 x 10 guide layout.
Zoom in to your required image size
Grab a screen shot of each guide square and save it with a coordinate.
That would reduce the printouts from 10,000 to 100.
It's a bit like banging your head on a wall. It's great when you stop.
It should be turned on by default, but if not, you can turn it on from the View menu
Then zoom in to something like 1200% and it will be visible.
Hello everybody.
I want to break down a photo into its individual pixels.
Is there any way to export every single pixel from a photo?
Thank you for your help.

You are going to get a lot of files and the script may take a while to run if you wish to crop/separate/divide/decompose/deconstruct an image into individual 1x1 pixels...
From this page:
https://www.andrewnoske.com/wiki/Adobe_Photoshop_-_Scripts_Related_to_Montaging
A simple adjustment to two lines will create 1 x 1 pixels from an image, ensure that you save into a new empty folder so that you can easily delete all the thousands of images easily:
/*
Original Script modified to create 1x1 pixel tiles
https://www.andrewnoske.com/wiki/Adobe_Photoshop_-_Scripts_Related_to_Montaging
*/
// Takes the currently opened image, and allows the user to split it into
// a grid of PNG tiles, by specifying an number of columns and rows and a
// base file prefix.
//
// Tiles are created by duplicating the original image, cropping then saving.
// Tiles are saved in the form: 'C:/path/prefix0,0.png'
#target photoshop
if (documents.length != 1) {
alert("You must open exactly one image in photoshop before running this script");
} else {
// Prompt user for number of columns and rows:
// var cols = parseInt(prompt("How many columns?", 4));
// var rows = parseInt(prompt("How many rows?", 4));
////////////// EDITED 2021 by Stephen Marsh //////////////
// Save the current ruler units and set to pixels
var savedRuler = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
var cols = app.activeDocument.width.value;
var rows = app.activeDocument.height.value;
var total = cols * rows;
/////////////////////////////////////////////////////////
// Determine target tile size:
var image = app.documents[0];
var tileWidth = image.width / cols;
var tileHeight = image.height / rows;
// Draw guides along cuts:
for(col = 0; col <= cols; col++) {
image.guides.add(Direction.VERTICAL, col * tileWidth);
}
for(row = 0; row <= rows; row++) {
image.guides.add(Direction.HORIZONTAL, row * tileHeight);
}
// Prompt user to confirm, and for file prefix to save out to:
var savePath = File.saveDialog("Save Image File Prefix", "");
if (!savePath) { alert("Cancelled"); exit; }
if(!confirm("Create " + total + " tiles, each of " +
tileWidth + " x " + tileHeight + "?\n\n\n" +
"Tiles will be saved as '" + savePath.fsName +
"1,1.png' '...1,2.png' etc")) { exit; }
// For each tile:
for(row = 0; row < rows; row++) {
for(col = 0; col < cols; col++) {
// Determine crop coordinates (in pixels):
var top = row * tileHeight;
var bottom = top + tileHeight;
var left = col * tileWidth;
var right = left + tileWidth;
// Duplicate image, crop, save as PNG and close:
var tile = image.duplicate(); // Duplicate file.
cropCurrentDocument(top, left, bottom, right);
saveTileAsPng(tile, savePath.fsName, col, row);
tile.close(SaveOptions.DONOTSAVECHANGES);
}
}
alert("Script completed!");
// Restore the ruler units
app.preferences.rulerUnits = savedRuler;
}
function saveTileAsPng(img, origFilePath, col, row) {
var newFilePath = origFilePath + "_" + col + "," + row + ".png";
var newFile = new File(newFilePath);
var pngSaveOptions = new PNGSaveOptions();
activeDocument.saveAs(newFile, pngSaveOptions, true, Extension.LOWERCASE);
}
// Crops active document by a rectangle with the given pixel coordinages.
function cropCurrentDocument(top, left, bottom, right){
app.preferences.rulerUnits = Units.PIXELS;
activeDocument.selection.select(
[[left, top], [right, top], [right, bottom], [left, bottom]],
SelectionType.REPLACE, 0, false);
executeAction(charIDToTypeID( "Crop" ), new ActionDescriptor(),
DialogModes.NO );
}
Results in the following for a 2x2px image:
