Are you asking about the quality of the photos or the value of the notes? If fr value, the $2 is worth $2 with no premium.
You would be better off with a scanner. The color is pretty off with the camera you are using. If you have photoshop maybe work on it a little. I turned what you have into this in a few seconds.
Oh, I think they are fine and everything can be easily seen. Not a problem I can see but I'm just going from a stand point as if I wanted to buy them.
I corrected the color. With more time I could make it look perfect. Feel free to message me if you need any help.
Cameras are fine, it's just that the red background is making the note look yellow. I take most of my photos on a windowsill and they come out blueish. (Look at my avatar). I just edit the color to look more normal
Tone down the sharpening a little... Research white balance. If you don't have any programs to tweak that or the camera's is a point and shoot than it's best to use natural sun light with the sun at your back... It's very typical for indoor lighting to make photos come out a little warm (Yellow)... I take a couple of steps to get the white balance collect, and typically the easiest is the shoot in raw, and use Photoshop else you would use the good old gray card which I actually still use to get the white balance right on. Sorry bro, it's not automatic or perfect, and most camera's get it wrong. Still no where as good as the human eye God bless those guys in the film days! Must of been heck to get that white balance correct!
the red back round makes it look pink. also try to get a straight shot. other than that they look good
