Well atmospheric perspective is basically using tone of color to show depth, whereas linear uses orthogonals. <span />
Sounds kinda gay if you ask me, but actually can you provide more context or an actual question ?
Answer:
The Battle of Gettysburg was fought July 1–3, 1863, in and around the town of Gettysburg, Pennsylvania, by Union and Confederate forces during the American Civil War. The battle involved the largest number of casualties of the entire war and is often described as the war's turning point due to the Union's decisive victory and concurrence with the Siege of Vicksburg.[12][13] Union Maj. Gen. George Meade's Army of the Potomac defeated attacks by Confederate Gen. Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North.
