To amputate a friends arm all you need is a camera, a raw chicken thigh, Photoshop and this straight-forward tutorial.
To begin you will need 3 separate photo’s all of which are taken at a similar time, with the same camera.
In the first photo the arm is resting on a bed with the camera focused on the elbow.
The second photo is taken from the same position but without the arm. So ask the subject to move out of frame, taking care not to disturb any of the creases on the sheets.
In the third photo we have an uncooked chicken thigh placed on a light-coloured plate. A knife has been used to rough up the skin around the end a little, and the camera is focused on this area.
(Remember to wash your hands TWICE after handling raw poultry!)
Now, in Photoshop open up the first image of the arm, then place the ‘no arm’ image on top. Reduce it’s opacity to around 50% and line it up with the image beneath, adjusting the scale if necessary.
Add a layer mask to this layer.
With the layer mask selected use a large black brush to mask out one side of the layer.
Now adjust the brightness/contrast so that it matches the layer beneath. When you have finished, delete the layer mask.
Use the crop tool to resize the image, leaving only the area where the arm will be.
Now open up your chicken image.
Use the Quick Selection tool to make a selection around the chicken thigh.
Take more care around the front area, the area towards the back will not be used.
Now paste your chicken into a new layer above your arm layer, and adjust the scale so it matches the arm.
Select your arm layer and create a layer mask.
In the layer mask use a large 0% hard black brush to mask out the rest of the body above the elbow, revealing the layer below.
Now move the arm layer so that it’s positioned above the chicken layer.
Go back to the arm layer mask and this time alternate between a small soft eraser and small soft black brush to blend the area where the chicken joins the arm.
Next click on the button shown above and choose Brightness/Contrast to create an adjustment layer above the c |
