To do this, I compared each shot and the corresponding hit in an image editor, using the &#8220;difference&#8221; blending mode. This mode brightens areas where two layers are different. I then manually aligned them so that details such as the sign, rock, and sandbags were as close as possible. Then I painted a small red dot on the &#8220;hit&#8221; image which corresponded to where the crosshair was when the shot was made. Here&#8217;s an example with the non-magnum run:<\/p>\n<div id=\"attachment_875\" style=\"width: 370px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/aligning.png\"><img aria-describedby=\"caption-attachment-875\" loading=\"lazy\" class=\"size-full wp-image-875\" title=\"aligning\" src=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/aligning.png\" alt=\"\" width=\"360\" height=\"691\" srcset=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/aligning.png 360w, http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/aligning-156x300.png 156w\" sizes=\"(max-width: 360px) 100vw, 360px\" \/><\/a><p id=\"caption-attachment-875\" class=\"wp-caption-text\">The non-magnum shot alignment<\/p><\/div>\n<p>This process yielded two &#8220;hit&#8221; pictures which show where the shooter was originally aiming.<\/p>\n<div id=\"attachment_879\" style=\"width: 370px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/nomag_comp.png\"><img aria-describedby=\"caption-attachment-879\" loading=\"lazy\" class=\"size-full wp-image-879\" title=\"nomag_comp\" src=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/nomag_comp.png\" alt=\"\" width=\"360\" height=\"225\" srcset=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/nomag_comp.png 360w, http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/nomag_comp-300x187.png 300w\" sizes=\"(max-width: 360px) 100vw, 360px\" \/><\/a><p id=\"caption-attachment-879\" class=\"wp-caption-text\">Non-magnum hit with aim indicator<\/p><\/div>\n<div id=\"attachment_878\" style=\"width: 370px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/mag_comp.png\"><img aria-describedby=\"caption-attachment-878\" loading=\"lazy\" class=\"size-full wp-image-878\" title=\"mag_comp\" src=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/mag_comp.png\" alt=\"\" width=\"360\" height=\"225\" srcset=\"http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/mag_comp.png 360w, http:\/\/technofovea.com\/blog\/wp-content\/uploads\/2011\/02\/mag_comp-300x187.png 300w\" sizes=\"(max-width: 360px) 100vw, 360px\" \/><\/a><p id=\"caption-attachment-878\" class=\"wp-caption-text\">Magnum hit with aim indicator<\/p><\/div>\n<p>Finally, we align both of these images so that the aim-points (red dots) are identical, and compare where the little puff-clouds kicked up from the shots are.
