There are not multiple image resolutions in what you provided or in the original PDF at the WH web site. There are the same number of pixels per inch in both signatures. If you examine both signatures in their entirety, you’ll see that the ‘A’ in “Ann” and the ‘D’ in “Dunham” appear just as “pixelated” as the ‘D’ in “David.”
Using different pens, inks, and/or pressure when signing names on the same document can and will result in lighter or darker signatures, which will result in exactly what you see. (It will do the same thing if the document is faxed.) Each pixel has an RGB (Red-Green-Black) value determined by the imaging software that digitized the document. Darker, fatter, heavier signatures (as parts of SAD’s are) can result in higher black values in the corresponding pixels. Lighter and thinner signatures can have lower black values.
I respectfully disagree with you. The D in Dunham for example is pixelated, but the rest of the signature is not.
Did you watch the orangegold1 YouTube sigment on this?
There are not multiple image resolutions in what you provided or in the original PDF at the WH web site. Lets look again:
Look at the 'm' in Dunham partially visible at the upper right. There you will see a couple of small pixels which you will not find duplicated in the Sinclair signature. These same small pixels are in evidence in the staircasing in the riser in the 'h' in Dunham, but not at all in the riser in the 'S' in Sinclair where the staircase steps are much larger. Note too that these two risers present at the same angle to the horizontal. They are clearly of different resolutions.
(Also of note is how the green safety background is disturbed in a completely different way by these risers even though that background is composed of "large" pixels throughout.)
