Making a Ghost
Photoshop Knowledge Required : Medium
External Plugins Required : None
(Before starting Reset your workspace by Window ---> Workspace ---> Reset Pallete Locations)
This tutorial enables you to create this type of a ghost...
In this picture I am making this 3d model a ghost. I got him from a wallpaper.
You can take a human's image too.
Okay so let's get started...
Use a picture taken in dark environment or which looks spooky.
Here I have opened a picture taken by me in the forest (Yes, I go out of the house too...)
Looks pretty scary eh?
Open up the picture of the person you want to convert to a ghost and the picture of the place too.
We will first make the model spooky and then extract his picture.
So first of all we have to convert the picture to Black/White
> Image ---> Mode ---> Lab Color
> Goto the channels tab and delete and one of the channels a and b.
> Image ---> Mode ---> Grayscale
> Image ---> Mode ---> RGB color
> Image ---> Adjustments ---> Brightness/Contrast {Contrast : 70 ---- Brightness : 15}
> Filter ---> Extract
{ Here you have to use the Edge Highlighter(B) to highlight the edges you wan't to extract and then fill the fortion with Fill Tool(G) }
> Select the Move Tool(V) and then drag the image of the model into the forest image, and set the new layer's blending mode to Screen
(Hint : You my need to resize the picture of the guy, Goto Edit ---> Transform ---> Scale and drag the corner of the image while pressing Shift, to get the desired size
> Ctrl+Click the new layer
> Select ---> Feather (5px)
> Ctrl + Shift + I, then press Delete
> Now select the Eraser tool(E) {Radius : depends ---- Hardness : 0 ---- Mode : Brush ---- Opacity : 100 ---- Flow : 100
Erase the legs of the ghost to be...
> You should be almost done. Now you have to play with the blending modes and opcaity to make the ghost scary.
Things you could do with the ghost:
I :
> Filter ---> Blur ---> Gaussian Blur (3px)
> Image ---> Adjustments ---> Brightness/Contrast (play with the settings)
II :
> Image ---> Adjustments ---> Hue/Saturation (Colourize : Yes , play with other settings)
III :
> Press D
> Filter ---> Distort ---> Diffuse Glow (play with the settings)
IV :
> Press Q
> Filter ---> Render ---> Clouds
> Filter ---> Render ---> Difference Clouds
> Image ---> Adjustments ---> Brightness/Contrast (play with the settings)
> Press Q again and the press Delete
V :
> Press Ctrl+Shift+E
> Image ---> Adjustments ---> Equalize
This is the final result... The results can be very different if you experiment.
Any Comments are appreciated.
