I this video I am going to show step-by-step how to install the CentOS 7 Linux distribution on VirtualBox for pure and open source virtualization of your testing and development environments.
Create a New Virtual Machine (VM) with the Virtual Machine Wizard, choosing Linux for the OS Type and Red Hat or Red Hat (64 bit) for the Operating System. Memory should be at least 768MB for a graphical install to work. Next the virtual hard disk wizard will start. The OS disk should be at least 8GB. For a relatively full install, allocate at least 15GB, otherwise use all the defaults. Additional disk[s] can be added later if desired.
In today's episode, we show you how to do Focus Stacking in Photoshop. We also give you some pointers on how actually shoot the images you'd need in order for Focus Stacking to work. We even briefly jump into Lightroom to show you how to prep your images. With a little help from our Game of Thrones figurines, we are ready to deliver an awesome episode!
What is Focus Stacking?
Focus Stacking is a technique where you can combine many different photos taken at various focal points. It's commonly used in macro photography where you have a very shallow depth of field. By combining multiple photos together you are able to extend your depth of field and get more in focus within a small frame. Focus Stacking is a great way to control what's in focus in your image.
Capturing Images for Focus Stacking
Focus Stacking is done in Photoshop, but in order for Focus Stacking to work you need to know how to shoot the images. So in today's episode, we give you a brief rundown of how we captured the images we used. With the help of some Game of Thrones characters we were able to create a little scene perfect for an example. We definitely encourage our Phamily members to get out there and have some fun with Focus Stacking. Not just in Photoshop but also in the Photoshoot process.
Here are some things you'll need in order to capture footage for your Focus Stacking:
A sturdy tripod (You'll need your scene to be relatively still in order to really achieve this effect. A sturdy tripod is one of the best ways to ensure your framing is consistent.)
A couple pocket wizards (This is totally option, but it was another way for us to get our hands off the camera, ensuring that the camera is shifting positions. We connected the pocket wizard with a shutter release cable and we were good to go!)
Shoot in "MF" also known as "Manual Focus" (Shooting in Manual Focus will allow us to move the focal ring of the lens while taking the pictures. The reason that we aren't shooting in Auto Focus is because Auto Focus would override what we are trying to accomplish by slightly moving the focal ring. Manual Focus gives us complete control of our depth of field.)
Capture images for Focus Stacking (There is a technique when it comes to Focus Stacking. Our advice is to choose your earliest stacking point, take a picture, rotate the focus ring a little bit, take another picture and repeat this process.)
Bringing Your Images into Lightroom
So now that we have our images for our Focus Stack, it's time to prepare them for photoshop. Our first stop is Lightroom, now only are you able to get an idea of the images you want to use for your Focus Stack, but you can also select the exact images you want to export to photoshop. We export and resize our images and now we are ready to rock in Photoshop.
Stacking Files in Photoshop
Now in Photoshop, we are ready to load all our images together. If we go to File - Script - Load Files Into Stack. This allows us to load all our images into one big stack instead of loading them individually. From there you can browse your files and choose the folder with the images you selected from Lightroom. There is an option in the Load Files Into Stack dialog box that says "Attempt to Automatically Align Source Images." We do recommend having that box checked. Once you hit OK, Photoshop loads all of those images into one stack. Now that we have the images loaded, we need to combine them all into one image.
Focus Stacking in Photoshop
The first thing we do is select all our files. We click on the first, hold down Shift, and then click the last to select all our images. Next we go to Edit - Auto Blend Layers. The two options that are now available to us our Panorama and Focus Stacking. We check the option "Seamless Tones and Colors" and hit OK. Now Photoshop goes to work, it takes the parts of each image that is in focus, then it creates a Layer Mask only revealing the part of the image that is in focus. Photoshop will use this technique on every photo in your Focus Stack. This automated process would be nearly impossible for us to do on our own. At the end of the process, we have our very own Focus Stacked image!

In today's special episode, we show you how to edit video in Photoshop! This is the first of a 4 part series on working with video in Photoshop, and covers all of the basics. You can also follow along with our video clips! Don't forget to download them here.
Why would you use Photoshop to edit video?? Well, a professional video editor is most likely going to use a video centric program rather than Photoshop (Adobe Premiere Pro, Adobe After Effects, Final Cut, etc.) However, it can be very useful to color grade your videos and apply filters to them- especially if Photoshop is the only program available to you. For someone familiar with Photoshop, this should come surprisingly easy. This is because you can think of editing video in exactly the same way as editing photos! It's practically an identical process, which can be a huge advantage.
Part I: Importing Video into Photoshop
1. For the first method for importing footage, go to File - Scripts - Load Files into Stack. From there, select the clips you are planning on working with by clicking Browse. After clicking OK, they will load into the same document.
If you are currently thinking, "Hey! Where do I see my actual footage?!" we have an answer for you! Simply go to Window - Timeline, and you will see the full length of each clip stretch out across Photoshop. This Timeline is the base for all of your video editing, and is where you will cut and arrange your clips.
By default, each clip is stacked up on top of each other. But this is not what we want! We need the clips to sit one after another in one solid sequence. To fix this, select all of your clips in the layers panel. Then, click on the little film strip icon on the timeline and select 'New Video Group from Clips.' You will see them group into one folder in the layers panel, and they will also be laid out horizontally on the Timeline.
2. The second method for importing footage starts by clicking Ctrl/Cmd + O (Open). Then, select which clips you would like to use. If you would like to add any more later, click on the film icon on the timeline and select 'Add Media.' Then, the additional footage is placed after the other footage in a linear fashion.
Part II: Using the Timeline
One of the first things you will want to know is how to rearrange video clips! This can be done by moving the layers around in the layers panel, or just dragging them left and right in the Timeline. To navigate through the footage, click and drag the red slider to scrub back and forth.
Part III: Editing Video
Next up is cutting and moving footage around. To cut a clip in half, place the red slider in the middle of it and press the scissors icon. Voila! It will be cut right down the middle. To delete any unwanted sections, just select them and press delete.
One nice thing about this is that you can always get back footage after it's gone! Hold your cursor over the beginning or end of the clip - wherever you cut it previously - and drag it out to include more video. This works the same for dragging the clip to be shorter as well.
Part IV: Using Keyframes
Keyframes are used to control certain changes over a period of time. A good example of this is making a clip slowly fade from transparent to opaque. Open the video group up on the Timeline by clicking the arrow. If you'd like to alter the opacity, pull your red slider to where the change should begin. Then, click the little timer icon to create a keyframe. A diamond will show up on the Timeline, which can be clicked on and adjusted manually. In this case, we leave the opacity at 0%. Then, drag the slider to where the change should end and create another keyframe. Click on it and adjust it again - in this case we change it to 100%. This causes the clip to slowly fade in, because we had a solid color fill layer underneath the clips. Keyframes can always be moved around and adjusted as well.
In today's episode, we show you how to color grade video in Photoshop! This is the second section of our 4 part video editing series, and it picks up directly from where we left off in the first section.

Why would you use Photoshop to edit video?? Well, a professional video editor is most likely going to use a video centric program rather than Photoshop. However, it can be very useful to color grade your videos and apply filters to them- especially if Photoshop is the only program available to you. For someone familiar with Photoshop, this should come surprisingly easy. This is because you can think of editing video in exactly the same way as editing photos! It's a practically identical process. Why not have a little fun!
Part I: Using Local Adjustments to Color Grade
Local Adjustments: Affects individual clips
To start off, select the layer you would like to make adjustments to. In the same way you would add adjustments to a photo, we can do the same for that video layer! Try it out by creating a new curves adjustment layer. After you adjust the contrast with curves, you will notice that it will clip directly to the single video layer you applied it to (be sure your clips are grouped into one folder). You can add multiple adjustments to the same layer, just like you could with a photo...cool!
Part II: Using Global Adjustments to Color Grade
Global Adjustments: Affects an entire group of clips (ie everything!)
To adjust all of your video footage at once, make sure that your clips are grouped into one folder (if they are not, you can select all the layers and press Cmd + G). Then, create an adjustment layer and place it on TOP of that video group. This will apply that same adjustment to everything consistently.
Part III: Color Grading Techniques
Let's get started with color grading! Create a levels adjustment layer, and select only the blue channel. Drag the black slider in to the right, and blue will be added into the shadows. Yellowish highlights tend to look great with cool shadows, so bring the white slider in towards the left to compliment them. Again, the more color editing knowledge you can pull from your regular photo editing skills, the better!
What if you create a global adjustment, but decide you only want it to affect some of your footage? Have no fear!! Notice that the adjustment layers stack on top of the video in the timeline. You are actually able to click and drag those adjustments and make them last as long or as short as you would like them to.
Part IV: Applying Filters to Video
In order to apply any filters onto video in Photoshop, it must first be converted to a smart object. So, select the layer you would like to affect, right click, and choose 'Convert to Smart Object.' Next, go to Filter - Filter Gallery. A preview window will load with an array of options. Feel free to play with the intensity and edges of the filters; you can always adjust the filter later as well. When you are happy with the way the filter looks, select OK. Then, you will need to render the clip. This is done by simply playing the clip. It will take a moment, and you will know it's done rendering by the little green line that appears on top of the clip afterwards,
And that's all folks! As you can see, there's no need to relearn much for editing video in Photoshop. Have a blast editing your own clips, or download ours for some great practice.
