Deke's Techniques 393: Assembling DICOM Slices into a 3D Image in Photoshop

Assemble DICOM Slices into a 3D Image

This week's free Deke's Techkneeques episode is a classic lemons-to-lemonade story. In attempting to keep up with the younger set, Deke not only sacrificed his knee to keep a volleyball in play, but continued to play for another two hours to prove he wasn't damaged. Which, of course, damaged his old-man knee. Which, in turn, gave him the chance to turn the DICOM files from his MRI into a 3D model of his injured knee. Read more »

What does that [insert quasi-enigmatic Photoshop feature] do, anyway?

It's concievable you could work with Photoshop for a considerable amount of time---twenty-five years possibly, as of this week---and still have features that are still a bit of a secret handshake to you. For Photoshop's twenty-fifth birthday, Deke has teamed with to create a series of videos:

These videos are free this week in honor of Photoshop's 25th birthday. Check out the list and click to shine the light of Deke's insight on any of these curious (but useful) Photoshop features: 

What do
blend modes do, anyway?
Blend modes allow you to mix Photoshop layers together in a variety of ways, allowing you to create compositions, colorizations, and other creations by simply changing how a layer behaves with regard to the layers below it.

What do blend modes do?


What do color modes do, anyway?
Color modes---RGB, CMYK, and Lab---refer to different ways Photoshop handles the color interaction inside of Photoshop.

What do channel operations do?
Before there were layers and other means of composition, there were channels. And channel operations, or chops, were the only way to make blended images.


What do healing tools do?
The healing tools are one of the primary weapons used in retouching, so for some, they are virtually synonymous with Photoshop.

What do layer masks do?
Layer masks (and their partner, adjustment layers) allow you to reveal only part of a layer, thus selectively revealing the contents of layers below.

What do sharpening filters do?
Sharpening allows you to increase the crispness of the image to really bring out image detail.

What do selection tools do?
Selection tools allow you to choose one element in your photographic image and isolate it from its surroundings.

Deke's Techniques 391: Chiseling Letters into Stone

Chiseling Letters into Stone in Photoshop


In this week's free Deke's Techniques video, Deke takes plain old type and turns it into chiseled letters of antiquity in Photoshop. The effect involves taking said ordinary type, turning it into a smart object, then adding a bunch of layer effects (of the Emboss nature mostly) and a bit of filtering.

Chisel letters into stone in Photoshop


Since this idea originally came about from a member request, I thought I'd see if I could recreate it on my own, using a different texture and type that I created myself. I used a bit of marble I found at and the Trajan font that comes with Photoshop CC that Deke suggests. With just a few color adjustments during the effects application (I made my shadows a little warmer, due to the color of my background), the technique was easily transferable to my own project:



For members of, Deke's got an exclusive movie this week in which he shows you how to create the chiseled border around the letters by adjusting the technique to use shape layers.

Deke's Techniques 389: Create Your Own Romantic Island Getaway

Create Your Own Romantic Getaway

My dekeDarlings. In this week's free Deke's Techniques movie, you'll see how Deke takes last week's smoothed over scene and enhances it to a suitable destiny for a romantic getaway, just in time for Valentine's Day.

Deke transforms a GoPro video into a lush romantic postcard.

To finish this enticing postcard of tropical transformation, which, as you may recall, started life as a lo-res video, Deke uses a combination of the new Adaptive Wide Angle filter to unbend the horizon, a Camera Raw filter to brighten and saturate the image, and the Smart Sharpen filter to firm up the mushy detail.

If you're a member of, Deke's exclusive technique this week shows you how to use a photo filter adjustment to bring out that azure blue of the tropical sea. If you're not a member of, you can get a free 10-day trial to check it out at Consider it our valentine to you! Read more »
