Detail of Erica-PSP8-15.jpg, magnified 4x in Photoshop and used a screen capture to preserve the pixel detail.

I specifically used a quality level of 100 or 99 in the original comparisons above.
Using anything less will result in the loss of pixel information as you can see.

Anyway, I'm not trying to start an argument here, just giving a heads up to the people who don't know that there IS a difference between JPEG output on various applications.

"Athanlore: excellent demonstration :D"
