[Pics] Manipulated Photos Of Notable Historic Figures Before The Digital Era (Before And After Images)

Manipulating photos happened way before Photoshop was around. This series shows before and afters of famous and notable figures before the digital era began. Truly fascinating, you can't help but wonder what level of dedication it took to make these happen.

The process used was not only clever darkroom techniques but also stitching various images together to create the after shots you see. Though, I am certain there's more to it and it's much harder than it sounds. Many of these are hard to do even in the digital era with Photoshop!

A photo of President Lincoln's head was placed on the image of Southern politician John Calhoun to create the portrait on the left.

Adolf Hitler had Joseph Goebbels (second from the right) removed from the original photograph after a falling out.

Perhaps in an attempt to not have his presence dwarfed, Canadian Prime Minister William Lyon Mackenzie King had King George VI removed from the original photograph of him and Queen Elizabeth.

The horse handler was removed from this portrait of Italian dictator Benito Mussolini to appear more heroic.

Russian magazine Ogoniok had the watch removed from a WWII soldier's arm as to avoid accusations it may have been stolen (as he is wearing another watch on left wrist as well).

The photograph of Ulysses S. Grant on the left is actually a composite of these three different photographs pieced together.

General Francis P. Blair (on the far right end) was added to this Matthew Brady photograph at a later date.

Like Hitler, Russian dictator Josef Stalin had a commissar removed from the original photograph after a falling out.

IPOL Journal · Image Processing On Line

Je viens de découvrir le journal IPOL : Image Processing On Line.
L'idée est de considérer qu'un article scientifique seul, sans le code associé qui a permis de construire et valider les résultats, n'est que la partie émergée de l'iceberg.
Je trouve que ceci est particulièrement vrai en analyse et traitement des images.

Ce journal vise à publier conjointement code source et article. Les deux étant relus et testés. Soumissions et consultations sont gratuites.

Nouveaux sites pour mes cours

Grace à la facilité d'utilisation de postach.io, chacun de mes cours sera accompagné d'un site dédié. Pour ce début d'année, deux modules sont concernés :

Sur ces sites : syllabus, contenus, diapositives, lectures obligatoires, énoncés de TD, ... Bref tous les documents utilisés pendant le semestre.

En Migration

Pixel Shaker est en cours de migration et sera bientôt de retour.
