Re: Realistic Shadows

An overall good book for many techniques, including shadows is How To Cheat In Photoshop by Steve Caplin. It focuses on the art of realistic montages, and is very well written.

Re: Realistic Shadows

Nice tutorial punkjunker!
This tutorial works with objects over the ground. There's a lot more
work to do when the object stands with legs, wheels, etc.

Re: Realistic Shadows

Photoshop has a shadow layer effect... just kidding, don't use that.

Being able to visualize what it is supposed to look like in real life is key. Make as many layers as needed to replicate and rob as much information as possible that was caught by the camera. Some times I have 2 layers, some times I have 20. I do all shadow work in Black only then turn off all layers except my shadow layers and duplicate my black channel (working CMYK). Add 3 points of noise to the channel (kills banding), push 3% off bottom of curve and pull 3% off top of curve to negate the noise added to pure white and pure black of channel. Make channel a selection, make new layer and fill with black only. I then delete my "working" layers so I am let with one shadow layer that is free of banding. If I need to add reflected color or want to go to a 4 color black near the object casting said shadow because it may need to be darker than black only will allow, I will create a new layer above that is using the shadow layer as a clipping mask, set to multiply and paint to desired effect. Convincing shadows are difficult to do.

Also note that shadow become more diffused and less dense the further away from the object that they are.

This is an example of robbing existing data. http://dvaught.com/portfolio/general/general_03.html

Here is are examples of creating what I would think would occur naturally

Re: Realistic Shadows

Funny that he reduces the size of the shadow. Shadows can never be smaller , only more diffused or bigger than the object casting them.

Re: Realistic Shadows

Thanks dvaught, your samples are great!

Alison thanks for the link. Nice tutorial. As pellepiano noted
I'm not sure why he reduced the size of the "wall" portion of the shadow.

I still would like to see what a pro does with a car or a furniture...
