Using a DSLR as a Digital Microscope

I’ve recently had the need to solder some small components at home, but don’t have a microscope, or even a decent magnifying glass. But then I thought that I’d a rather expensive DSLR and a pretty good macro lens, along with some extension tubes (allows closer focussing). Now I know that the camera has a Live-View facility (it’s a Canon 5D Mark III), but would the display be output easily to a monitor? Well, in the box that came with the camera, I found a cable which had a composite connector and some kind of A/V connector for the camera, so I set it up as shown in the pictures, a switched on the camera. The menu was displayed on the monitor, as hoped. Once I’d enabled live view and adjusted the settings so the exposure was OK, I zoomed into the display, first x5 and then x10. Each time the live view display was replicated on the monitor.

Photoshop L-Plates

New to the “Photoshop Parody Plug-ins” collection – “L-Plates” for Photoshop. This is a clever little plug-in that you can give to all your friends who produce endless over-saturated, over-processed images. Now, with “L-Plates” you can configure how far they can push each slider in Photoshop.

For example, the default setting in L-Plates for the saturation slider is 15. This means that the use cannot physically push the slider past 15 without getting an over-ride code. And you’re not going to give that code to them, are you? Because you’re so used to seeing images with the saturation slider up around 40-45 (and beyond). Continue reading »

Photoshop Extreme Makeovers

My daughter wanted to be an Avatar, because she happened to see a video on YouTube of Venessa Hudgens being given the Avatar treatment. I had a good look at the video, and gave it a go. Here’s the result:

Also, if you want to give it a go yourself, here’s the YouTube video by NEATeyePHOTOart I used as a guide:

Once I’d completed the Avatar daugher, my other two wanted their own makeovers. So they chose the vampire style of the movie “Twilight”. Here’s the before-and-after from each of their makeovers.

and

The most difficult part of the vampire makeovers was the removal of the freckles in the first one. I was told that vampires dont have freckles. Something do do with skin pigment in vampires. Where they got that from, I don’t know. Anyway, they were insistent that I take out the freckles. I think they were right, it’s a better result because of it.

Adobe Photoshop CS5 Arrival

I just took delivery of Adobe Photoshop CS5. I had recently got CS4, and decided that I’d like to keep up-to-date with the latest version, especially with all the rave reviews of the new “Content-Aware Fill” feature that everybody is going on about. Having played with it in the trial version, I decided it was worth the upgrade. I haven’t tried it for real yet, only on some test images, but the results of the Content-Aware Fill look nothing short of magic. I was working on an image of the Dolmen in Poulnabrone, and used this feature to remove those damn ropes that surround it. Not only did it do a nice job of removing the ropes and rope-stands, it filled in what it removed with rocks, shadows, highlights, etc, which all made for a retouch that is very hard to tell from the real thing. Much better (and faster) than the older patch tool in CS4.

Photo Retouching

I just subscribed to www.GuyGowan.com. He’s a photo retoucher and Adobe Photoshop Trainer, and I happened to see a couple of his seminars at Photofest in Dublin in April 2010. The stuff he does with channels in photoshop is nothing short of amazing. It really does speed up workflow. Also the emphasis is on non-destructive methods, and natural-looking retouches, so using a combination of curves and channel masks, all the retouches work with the image, making the changes as natural looking as possible. There’s also a method of doing HDR withouth any 3rd party program or the HDR action in photoshop. The result is  a very dramatic, natural looking image with all the dynamic range of a HDR, but without the halo’s and other negative effects you usually associate with HDR. If you get a change to catch Guy in a seminar near you, he’s defintely worth a look.
