My last tag tests were with basic painting words, "brush stroke" and "brush strokes". As you could see the pluralizing made a difference to the AI software when it was creating an image.
This time I wanted to see if capitalizing made a difference to the Text to Image software.
Here are the new images created using the same tags but capitalized compared to the previous tests with no capitalized letters.
"BRUSH STROKE"
vs
"brush stroke"
The software never makes the same exact image when using the same tags but there does not seem to be much of a difference, other than slight paint placement, when capitalizing letters.
"BRUSH STROKES"
vs
"brush strokes"
The cloudy white parts of the capitalized version and a little bit more red but that's still not enough of a difference to make me think capitalizing letters matters. Maybe it will make a difference when trying to get the software to create letters in the image but not with in the case of these tags.
