Skeletal Remains


Skeletal Remains, originally uploaded by the patter.

These are the remains of a flower (a Day Lily) at the end of autumn. I set up a small black card as background, held the subject upright with some play-dough. I used a 50mm lens with extension tubes and lit it from the side with off camera flash.

This was a simple set up and subject, but it got me to thinking a lot about how I might expand the set up and use different plants, etc. This photo won 1st prize at the Westbridge Camera Club's monthly competition. Since making this image, I've started work on a series of images, one of which has also won first prize. More to come on the series, but for now, enjoy!

Boyer Boutique Shoot

I recently finished shooting the product line for the Boyer Boutique. They specialize in custom chocolate gifts and handmade cards. The Boyer's are some of the nicest people you'll ever meet, so it was a real pleasure to help out with images for their website. For any guys reading this blog, here is a hint: Now is the perfect time to check out the Boyer Boutique! They have their Valentines gift line on their site. If you are not sure what to give that special girl this Valentine's, here is the place to go for a unique, thoughtful gift!

Though I do a lot of macro and close up photography, shooting candy/food is really a lot more challenging. Of course you want your image to appeal to the viewer as an appetizing treat, but there are also technical challenges as well. For instance, anyone who has photographed food before knows that some dishes only look ideal for a brief period of time. Fortunately I have a 'sun room', which is a true misnomer in Ohio in January. The room is cold during the winter months, so I didn't have to worry about the chocolate melting or softening from the temperature of the room. I also use small, battery powered flash units, so heat from the lights did not affect the product either.

A big challenge I faced with this shoot was dealing with reflections. Since some of the products are in glass bottles, I had to contend with some unwanted reflections. For instance, take a look at Figure 1.

Notice the white line just to the left of the '9'? That reflection was probably flash spilling onto the white T-shirt that I was wearing. So to kill that reflection, I used a 'flag'. I had a black piece of foam core that I held below the camera in lens in a position that would prevent the light from reflecting back into the glass. A simple fix, but one that I normally wouldn't have to worry about with a bug or a plant!

The Figure 2 shows the image with the white line eliminated.

Here is the set up shot showing me holding the flag (the black square in the bottom/center of the image) to block the reflection. I guess I should have worn a black turtle neck!

A Fly Flew By

Fly

Remember the scene in 'Karate Kid' where the student tops the master by catching a fly with chopsticks - something the master had never accomplished after years of trying? Is this shot the same sort of thing? A happy accident where the fly flew into focus at the precise moment? Not exactly, and the Flickr description is far-fetched...click on the photo to jump to the Flickr image.

Macro Primer Pt II - Reversing a Lens

In my first article, I wrote about close up filters, an inexpensive way to get into macro photography. In this article, I will be talking about another way to "create" a macro lens. Depending on your situation, this may also be an inexpensive endeavor.

Let's say you just walked your old 50mm lens out to the curb for trash man to pick up. You used it with the old 35mm film camera, but maybe the mount is different than your DSLR or you switched camps and have no use for the old lens.

WHAT ARE YOU, NUTS?!?! YOU JUST THREW AWAY A FREE MACRO LENS! Get back out to the curb NOW!

That's right, if you have an old lens laying around, you don't have to pay another cent. The really great thing about this is that it doesn't matter what brand of lens you reverse. Canon, Nikon, whatever you have on hand

When I bought my Nikon, I thought my old lenses would fit the D50. Turns out most of my lenses are just a little too old. Too bad because I had quite a few. Then I discovered that if you have a lens and mount it to the camera backwards, voila, you have a macro lens.

There are two ways to use your lens backwards. One is an adapter that will let you mount the lens backwards on the camera. I've even seen a DIY adapter, though personally I would not use it since it is constructed of plastic and epoxy. Probably not a big deal, but the adapter will probably run you about $15 so DIY will not yield a big savings here.

The second method, which I use, requires two lenses. It turns out that the 80-200mm zoom lens that I had for my old Nikon F does fit the D50. It's not a fast lens and I probably wouldn't use it for much else anyway. I also have a 50mm f1.4 that does not fit my D50. Both lenses happen to take a 52mm filter, meaning the front of each lens is the same diameter.

To create my macro lens, I put the two lenses together, as shown in the picture below.

When I first read about this, I was eager to find out how well this would work, and I couldn't locate a macro coupler. So I improvised and used a piece of electrical tape to hold the lenses together. Since I consider this a dedicated macro lens, this works great. The original piece of tape is still holding the lenses in place a year later. I know I dismissed the DIY adapter a minute ago as risky, but really, the tape does work well.

If you want to find the macro couplers, check here.

What you need to know about this technique is that you have to be extremely close to your subject. Here is why: under normal circumstances, the lens element is designed to focus on the film plane. When you reverse the lens, that distance doesn't change - but instead of the film plane, your macro subject is in that location.

Another important fact, the faster the lens, the better. Unless you are going for a vignette effect, you want the reversed lens to be set to its widest aperture. Also, depth of field is extremely shallow with this technique.

In the previous article, I showed samples of how close you can get with the close up filters. As a reference, here are two shots from last time, and below that two shots with the reversed lens technique.

Obviously your results will vary, depending on what lenses are used to comprise your macro lens. Ready for some real world examples? Here are some critters who were cooperative enough to let me get close to them. For reference, the spider descending toward my face was approximately a quarter of an inch in diameter.

A Little Macro Primer - Close Up Filters

Want to try your hand at macro photography, but you are hesitant to drop $500 plus on a macro lens? Then this little demo is for you. I am going to explain two tools that I use when shooting macro. Neither one is terribly complex and by photographic equipment standards, both are fairly inexpensive.

In this first article, I want to talk about close up filters. I am always surprised that more people don't seem to know about these, because they are easy to use and carry, and can even be used with some point and shoot type cameras. In fact, I first tried these with a Fuji S5000, and then later purchased a set for my Nikon DSLR.

mCloseupFilters_001

To use a close-up filter, you attach it to your lens just like you would any other filter. You can also add more than one of these filters at once, enabling you to greatly increase the magnification of your macro subject.

There is a quality cost for doing so, though. The higher the magnification, the more you will see chromatic abberation or color fringing around the edges of an object. To demonstrate this, I have taken photos of a couple of household objects at various magnifications.

Here is our base photograph taken with my Tamron lens @300mm.
300mm zoom, no close up filters

Below on the left is pretty much the same shot, same lens, but with a +1 filter added (I did have to adjust the camera closer). As you can see, there is not a great deal of difference between the +1 and the base photo. When I add the +2 close up filter (right), the difference is a bit more obvious.
+1 filter +2 filter

At +4 (left) you can see the color change around some of the edges of the ruler. On the right is a photo with all three filters stacked, for a +7 magnification.
+4 filter mMacroDemo_015

Look closely at the shadow around the bottom of the ruler for a hint of blue that should not be there.
+7 stacked close up filters

Macro photographers tend to work with a very narrow depth of field, and these filters are no exception. Aside from the color issue, you will notice that less and less of the ruler is in focus as our magnification increases. You can extend the depth to some extent by controlling the aperture.

With the set I own, you have to stack them with the lowest magnification closest to the lens, then build up. If you put the +4 on first, the next filter will rub against the glass, because the curvature of the glass extends beyond the depth of the mounting ring.
mCloseupFilters_002

You should be able to find them at any good camera shop. If you want to find them online, check out Adorama.

What can you really do with these? See the photo below:
