The sharpness is not a grade of the image, instead are indications of the actual conditions at the time the scenes were photographed.  Eastern scenes generally have some haze and are less defined and less imposing than western scenes.  All scenes are designed as backdrops to blend into your layout.  BackDrops may be super sharp with detail at 3 inch viewing distance with A and A+ sharpness code.

Sky codes E=Eastern,  W=Western,  none=older variations mostly western

For HO scale 36 inch high

Some scenes have nothing in the foreground so there is no  reason to scale the scene down for HO.  We use the same scene (scale) as for O scale.  Those scenes are indicated on the stock number page as Category ?O, example AO or CO.  If you want more sky and less scene, tell us or add an S to the end of the stock number or to force the largest add an L.  This applies only to HO using 36 inch high scenes. Some scenes have a 1/2 size version with a link "reduced size" to left of  "shown 36x12" . L on stock number means no 15-20% reduction on 18,24,36 sizes. More info on scale
SHARPNESS CODE:

A+  Maximum sharpness, color, contrast, detail, wow!  Applies to BD (BackDrops) only

A    Very sharp, no haze, high definition, much detail, usually western, some eastern

B    Moderately sharp, a little haze, varied definition, not as imposing as A, usually western, some eastern

C    More subtle, some haze, possibly high contrast between snow and trees, much less individual definition, much less imposing than A or B, tending toward a painting also may be image with earlier technology not as sharp as more recent scenes .

D    Moderate definition, haze in background, closer objects somewhat clearer, usually eastern agricultural and hills, may be image with earlier technology not as sharp as more recent scenes .

E    Low definition foreground, heavy haze and lower definition in distance, usually eastern mountains, may be image with earlier technology.

F    Very Low definition, heavy haze, little to no detail, tending toward a painting, usually eastern mountains

G    Moderate to high definition over most, usually eastern cities and commercial    

H    Low to Moderate definition of cities and commercial.     
Scenes from one location can be used for another.  Many parts of the country look similar to other locations.  Example: Colorado agriculture may be similar to some California agriculture.
