There are many simple modelling programs out there, including Adobe’s own Fuse (available to download for anyone with a CC subscription). Fuse lets you create 3D characters by piecing together body parts and clothing – it’s so simple that even a complete novice can create a customized character in minutes. Characters can be synced to your Libraries panel, then used in your 3D projects in Photoshop. You can even animate the character, using preset animations like dances or fight moves. To do so, highlight the model in the 3D panel, choose an animation in Properties, then use the Timeline to scroll through the animated sequence. STEP 1 BODY-BUILDING Download Adobe Fuse using the Creative Cloud App and start it up. The program is very simple: just choose body parts, clothing,…

WATCH THE VIDEO http://tiny.cc/ogyyjy CMYK Standing for Cyan Magenta Yellow Key (Black), CMYK is for printing and pre-press purposes. The color values relate to the amount of ink needed for each. A print can never be as bright and vibrant as a digital screen, however, which is why you’ll often see colors dulling down when they’re converted to CMYK. You can get an idea of the channels that make up the image with Window > Channels. PROPHOTO Prophoto is the widest color space Photoshop offers, encompassing even ‘impossible’ colors. The upshot of using this broad gamut is minimal color degradation during processing. Set up Prophoto (Edit > Color Settings > RGB) if you work with raw files or use Lightroom (which uses Prophoto). Keep in mind, though, that it’s the…

Grab the Move tool and click on any 3D shape and you’ll see a colored three-way axis widget. This lets you change the position of 3D objects, meshes and lights. Each of the three directional lines – X, Y and Z – has three controls. The arrowhead lets you move the object along that axis. The little bent line lets you rotate the object, while the little rectangle stretches or shrinks along that line. If you want to scale uniformly, drag the centre square. As these three controls are often close together or overlapping, it can be tricky to latch on to the right one. It might help to resize the widget – hold Shift and drag the centre square up to make the axis widget larger. Sometimes the axis…

Rendering is the single biggest pain with 3D editing. It can take ages – especially with large image sizes and complex or transparent objects. Not only do you need to render the scene at the end of the project (click the Render button in the 3D panel for this), you also often need to render as you work, to check that the lighting and materials are looking the way you want them to. Fortunately, you don’t need to render the entire image every time. Instead, you can make a rectangular selection over a portion of the model with the Rectangular Marquee tool, then click Render. Now it’ll only render the selected area, which will take much less time. While your computer is rendering, you can see the progress in the…

As any photographer knows, your choice of focal length and depth of field can have a dramatic effect on the look of a photo. When it comes to editing in 3D, you also have control over these factors, using the virtual camera that presents your scene. With Current View selected in the 3D panel, the Properties panel lets you alter Field of View (FoV). This is like the focal length of the camera’s lens. A long focal length means objects will look more compressed, while a wider length means more foreshortening and distortion. Once you’ve altered the FoV, you usually need to adjust the camera position too by moving closer or further away. To do this, use the dolly move control (accessed at the top of the screen when the…

01 CHANGE TO LAB Lab is a mode that separates color and detail, which makes it great for boosting weak hues. Go to Image > Mode > Lab Color. Open the Layers panel, click the Create Adjustment Layer icon and choose Levels. Click the dropdown menu at the top. It shows Lightness, A and B. Select A. WATCH THE VIDEO http://tiny.cc/heyyjy 02 SQUEEZE THE SLIDERS You can boost colors by dragging the black and white points inwards by equal amounts. Using the boxes below the graph, set Blacks to 50. The tonal range is 0-255, and 255 minus 50 is 205, so input 205 in the Whites box. Select the B channel and again squeeze in the white and black points by equal amounts. Flatten the image and convert back…

Sometimes you’ll convert images to CMYK for printing. You could just go to Image > Mode > CMYK [1]. However, this may have a dramatic effect on the color and saturation – especially blues and cyans [2]. This is because RGB and CMYK are fundamentally opposite. RGB is additive, meaning that adding more of each color will eventually lead to white. With CMYK the starting point – the paper you print on – is white: as color is added, you get further from white and closer to black. Before converting, go to View > Proof Setup [4] and choose Working CMYK, then View > Proof Colors. As displayed in the file info [5], this lets you see how the image will look in CMYK while still allowing you to work…

WATCH THE VIDEO http://tiny.cc/v40yjy You can extrude any 2D shape you like into a 3D object – including text. Simply make the shape on a new layer, then go to 3D > New 3D Extrusion From Selected Layer. Photoshop’s 3D modelling tools are quite basic, so you’re limited to a few simple controls. You can change the extrusion depth, add bevels and caps to inflate the surface, and twist or skew the extrusion. But even these enable you to create all manner of interesting shapes. There are also a few basic meshes you can use, like spheres, cubes and pyramids. STEP 1 MAKE A 2D SHAPE Any shape can be extruded to 3D. Here we begin with a 2D vector shape (downloaded from the Creative Cloud App Assets). Make a…

For beginners to 3D, it can take a little time to get your head around navigating 3D space. Every object has its own X, Y and Z coordinates to place them within the scene. Imagine a huge empty room where objects can be positioned anywhere, from ceiling to floor and from wall to wall. As well as positioning your objects, you also have control over the view of those objects. Sometimes this can lead to confusion: you might think you’re moving the object, but in fact you’re moving the camera’s view of it instead. Keep tabs on what is selected in the 3D panel. If the 3D shape is selected, the Move tool will let you reposition it; if Current View is selected, you can pan, dolly and zoom the…

There are lots of 3D models online that are ready to download and import into Photoshop – and many go way beyond the level of modelling achievable with Photoshop’s 3D tools. A good source of free online models is archive3d.net, which houses thousands of downloadable models like the scorpion here – although many come in file formats not recognized by Photoshop. Here are the 3D file formats that Photoshop can open: 3D STUDIO (IMPORT ONLY) DAE (COLLADA) FLASH 3D* (EXPORT ONLY) JPS* (JPEG STEREO) KMZ (GOOGLE EARTH 4) MPO* (MULTI-PICTURE FORMAT) U3D WAVEFRONT|OBJ STEP 1 DOWNLOAD A FREE MODEL Go to archive3d.net and choose an object to download, making sure the file format is compatible. Once it’s download, open it in Photoshop. Often, like the scorpion here, you need to…

Once you’ve rendered your scene, you might notice that something needs a slight visual tweak. But ask yourself: is it really worth waiting for another render? For simple adjustments to the lighting or brightness, it might be easier to finish off the job with Photoshop’s easier tonal tools rather than spending more time in 3D mode. So try merging a new layer by pressing Ctrl/ Cmd+Shift+Alt+E, then use tonal tools like Curves, the Camera Raw filter (pictured) or the Dodge and Burn tools to perfect the look of the scene. Every Photoshop tool is at your disposal……

WATCH THE VIDEO http://tiny.cc/xiyyjy CUT OUT A PERSON All cut-outs start with a selection. While there are several tools for the job, the Quick Selection tool is often the easiest and best. With this tool active, paint over the subject, then hold Alt and paint in any areas where it latches onto background detail. Continue until you have a decent selection. Next, you need to click the Select And Mask button (or Refine Edge in older versions of Photoshop). The Radius controls are key here; increase the Radius to expand the area of refinement along the edge of the selection. Next, choose an Output setting – either Layer Mask or New Layer depending on what you want to do next – then click OK. Now you can try out these…
