Creating Depth of Field in Photoshop

In this episode I’ll show you how to create an artificial depth of field effect in Photoshop, using the Blur Gallery. This can be useful for cutting down on render time, or to apply to images that have been taken with small fixed focus cameras (like the GoPro).

This technique is similar in style to this new “portrait mode” on iOS devices. The Blur Gallery has a lot to offer, I’m only scratching the surface by demonstrating both the Tilt/Shift and Iris Blur filters.

Creating a round cutout mask for OBS Studio

I like the way my PlayStation 4 adds a soft round cutout mask to the PlayStation Camera Feed when streaming gameplay. I wondered how I could best recreate this effect in OBS Studio for a consistent experience, no matter which device I decide to stream from.

Here’s how I did it, with a little help from Photoshop – feel free to use the resulting asset without any need for further fiddling.

Creating a Zoom Blur Effect in Photshop

In this episode I’ll show you how to create a moving Zoom Effect in Photoshop, using the Radial Blur Filter. I’ll also explain the use of Smart Objects and how to blend the original image with the blurred version using a Layer Mask.

I’ve used this effect to create the thumbnail for my Vertigo Shot animation here: https://youtu.be/M-UevHx5CsQ

How to turn a Raster Image into a vectorised SVG in Photoshop

The other day I wanted to convert a logo into a path, so that I could use it as a shape in Blender. It was in fact the WordPress logo that was provided as a PNG or PDF from the WordPress Branding section.

The trouble was, both the PNG and the PDF are rasterised, and as such cannot easily be used for an extrusion in 3D as an SVG file would. The question then was, how do I convert an image into an SVG in Photoshop, so that I could import it into Blender?

It took a bit of fiddling, but here’s how I did it.

Quick introduction to SVG Files

SVG files can actually contain three types of data:

  • Vector Graphics, such as paths (which is what we want)
  • Raster Graphics, such as bitmap images (which we have, but don’t want)
  • and Fonts

What I needed in Blender was indeed a Vector Path. Although the other two data types can be contained in an SVG file, Blender can only read path information at the time of writing. It makes sense too, because really I’d like to the path information available as a curve in Blender, not the potential raster or font information.

I’m mentioning this here because

  • a.) I didn’t know this, and
  • b.) importing an SVG containing either fonts or raster graphics will import nothing into Blender – which had me stumped.

Thanks to cegaton on Blender Stackexchange for this explanation!

Hence, for Photoshop to export vector data instead of raster data in our SVG file, we need to jump through a few hoops – but it is possible. Let’s see how!

How to pixelate text in Photoshop

In this screencast I’ll demonstrate how to pixelate or obfuscate text in Photoshop.

I usually use Skitch for such things, but one day it wasn’t working, and all I had to hand was Photoshop – so I hunted around and found that it works just as well. It’s just knowing what to click. Once I figured that out, I thought why not share it with the world.

Here are some written instructions, just in case you’re not a video person.

Using the rectangular marquee tool (M), draw a selection around the area you’d like to pixelate. 

Now head over to Filter – Pixelate – Mosaic to bring up a little dialogue box.

Here you can select the Cell Size, meaning how pixelated you’d like the selection to appear. Photoshop even gives you a preview option – how nice is that?

When you’re happy, click OK and Photoshop will burn your pixelation into the selected layer. Press CMD+D to deselect the marquee, or head over to Select – De-select. Next, share your anonymous masterpiece with the world.

Happy pixelating!

How to create a Bokeh Effect in Photoshop

Photoshop has an interesting set of filters that let us turn ordinary images into fascinating Bokeh Effects. Those can be useful as a nice alternative for gradient backgrounds due to the elements of randomness they can bring, or for foreground effects akin to those created with plastic cameras. 

The above uses a Bokeh Effect as additional foreground pattern. Let’s see how it’s done. Continue reading How to create a Bokeh Effect in Photoshop

How to open and convert multiple raw images in Photoshop

Opening several JPG or PNG images in Photoshop is the easiest thing in the world: just select several in the Windows Explorer or in the Mac Finder, right-click to choose Open, and Photoshop brings in each image as a new document.

But when we try the same with raw images, it won’t work: although Photoshop shows us the raw processing dialogue for all our chosen images, and lets us make individual changes, as soon as we hit Open at the bottom, only the current image is opened as a new document.

What gives? How can we open and convert several images at once? Continue reading How to open and convert multiple raw images in Photoshop

How to draw with an image in Photoshop

Sometimes we want to reproduce an image using a brush stroke. It’s a handy way to replicate a 2D object along a path for example. Using the standard brush for this though, we’ll find that we can only reproduce a single colour image. But what if we want to reproduce all colours in our image?

Enter the Mixer Brush Tool. Here’s how to sample an image and draw with it in Photoshop. Continue reading How to draw with an image in Photoshop

How to create a drape effect in Photoshop

It’s easy to create an effect of draped cloth in Photoshop, like in the image above. We can do this with the Gradient Tool. It’s the icon with an actual gradient on it, sometimes hiding behind the Paint Bucket or 3D Material Drop tool (if you don’t see it, left-click and hold for about one second for the multiple icons to appear, or press the keyboard shortcut G repeatedly).

Once selected, choose Difference as the mixing mode at the top left of the screen, and make sure that the colours are set to back and white (other colours can give “very creative” effects shall we say).

Now start moving your cursor in short strokes from left to right, then right to left. Every time you change direction, the image is inverted. Add a diagonal strokeĀ in every so often. You’ll create magnificent drape effects in no time!
