The latest and greatest version of Adobe Photoshop CS5 natively runs in 64-bit mode on both Windows and Mac. This is good news for us because this means that, especially on a Mac, Photoshop runs much more quickly. Yet, there are a couple little features that you can't access in the 64-bit mode. One of those is Render, Lighting Effects. What I want to do here is simply show you how you can launch up Photoshop in 32-bit mode if ever you want to use this particular Filter. So, all that you need to do is you need to navigate to where your Photoshop application icon is.
Next, you can either right-click or Ctrl +Click this icon and there you go ahead and choose Get Info. This will open up this Info dialog. What we're going to select here is Open in 32-bit mode. Now, all that we need to do is to double -click on our Application icon in order to open up Photoshop in 32-bit mode. From this point, I'm going to go ahead and navigate to Bridge. I'll do so by clicking on the Bridge icon, and I'm going to bring this file, light.jpg, into Photoshop. I'll do so by double-clicking, pressing the F key to go the Full Screen View mode.
Now here what I want to do is I want to add this lighting effect to this particular photograph. I'll do so by copying my Background layer, press Command+J or Ctrl+J. Let's zoom in a little bit, so we can actually see the image there. All right. Let's name this new layer, light. Next, we'll navigate to our Filter pulldown menu. Here we're going to go ahead and choose Render. Now that we're running in 32-bit mode, you can see that we have access to Lighting Effects. A lot of photographers really like this dialog. That's why I wanted to show it here.
In my case, I'm going to choose Omni. I just want to add a little bit of a light source to the subject, and I'll make this a touch bigger, just kind of redirecting the overall focus. Then I can dial in my settings as needed. I'm just going to work on this just a bit. Typically, you want to take this over more than you're comfortable with and then click OK. From there, we're going to drop this down to probably 10% or 20%. All that this is going to do for us is, again, redirect the eye. Here is our before and then after.
I'll crank it up a little bit higher so we can see that perhaps even more. Here we have it, before and then after, bringing light into this area of the photograph. That's a bit too high for my flavor, so I'll go ahead and lower this effect. So, that's a touch lower there. Again, there is before, and then there is after. All right. After we've accomplished this task with this particular Filter, what we would want to do is save and close this file. So, I'll go ahead and save this one out and then close it. I of course, want to quit Photoshop and then go back to that area where I have my Finder Info open.
Click off the option to open in 32-bit mode. We definitely don't want to leave that on, unless, of course, we're trying to accomplish a task which requires it. Next, we can simply double-click on the Photoshop icon in order to open up Photoshop in 64-bit mode.
