This 32K JPEG image of Picard was scanned at 100DPI from an 8X10 inch print that was a 5X enlargement from the 8X10 inch negative. Each pixel is 4/10 the size of the smallest resolvable object.
File size: 215K.
Print: 10X enlargement of the wall of Picard facing the
camera at the position of the main "arch" in AS10-4421.
Printed on high-contrast paper.
Digital Scanning: 100 DPI.
Resolution/Pixel 1.2 resolution lines per pixel.

This 363K GIF image of Picard was scanned at 100DPI from an 8X10 inch print that was a 3.7X enlargement from the 8X10 inch negative. Each pixel in this image is 3.2 times larger than the resolution limit of the camera.
This 85K GIF image was made from an 8X10 inch print enlarged by 9X from the 8X10 inch negative originally received from NSSDC. Each pixel is 1.3 times larger than the camera resolution limit.
This 32K JPEG image of Picard was scanned at 100DPI from an 8X10 inch print that was a 5X enlargement from the 8X10 inch negative. Each pixel is 2.5 times largers than the theoretical resolution of the camera.
File size: 250K.
Print: 10X enlargement of the wall of Picard facing the
camera at the position of the main "arch" for comparison with AS10-4417.
High-contrast paper was used.
Digital Scanning: 100 DPI.
Resolution/pixel Ratio: 1.2 resolution lines per
pixel.
Note: Lunar orbiter high-resolution photographs were long strips that were divided into three separete photographs, and the principal point is always in the middle section, or in LO4-191H2 in this case, and not in section H3 described here.

File size is 396k. This image was scanned from an 8X10 inch print that was made from a 10X enlargement of the photographic negative. The scan resolution was 200DPI. Each pixel represents 2.8 arc-seconds, which is about 1/3 the angular size (4.4 arc-seconds) of the smallest object resolvable by the Lunar Orbiter high-resolution camera at a 3:1 contrast ratio.
