Backlit Orchid

ktuli — Thu, 02/09/2012 - 18:43

For this shot, I asked my lovely assistant to position my flash behind the orchid to produce a different view and get those nice highlights along the edges of the petals...

Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM, 1/200 sec at f/22. Canon Speedlight 580EX II flash in auto mode and wireless control. Image Stabilization on. ISO 100. RAW processing in Adobe Camera Raw.

Focal Length, Field of View, and Perspective

ktuli — Thu, 01/19/2012 - 21:41

If you've been following along (or checked the equipment list), you might have noticed that I now own four different macro lenses. You might also wonder why one would need that many different specialty lenses.

The answer is that each one provides a different focal length (35mm, 65mm, 100mm, and 180mm). While each one provides a different working distance to the subject, that causes different perspective, and also a different field of view. The field of view is basically the amount of the scene that is in the frame. Perspective can be thought of as the relationship of foreground elements to background elements.

35mm
100mm

Technical Data: Canon EOS 7D, Tokina AT-X M35 Pro DX AF 35mm f/2.8 Macro 1:1 and Canon EF 100mm f/2.8L Macro IS USM respectively, 1/30 and 1/80 sec respectively at f/2.8. ISO 100. RAW processing in Adobe Camera Raw

In this case, I kept my foreground subject almost identical in the frame, but if you look at the background, you can definitely tell a huge difference. Here, I used a wide aperture to get a shallow depth of field, so the background is pretty well blurred and full of soft bokeh.

However, if you look at the shapes of the background, you can definitely identify a couple major differences. First, the 100mm shot has a much less cluttered background because it has a much smaller field of view. Additionally, the perspective causes the background elements to appear much larger in the frame (and thus making them seem closer).

Orchid Abstract

ktuli — Sun, 01/15/2012 - 22:58

One of the things that happen when you start working with macro photography is that you often lose perspective and cross over into a realm of abstract. Magnifying things we don't normally see, and some that we can't even see with the naked eye can certainly put someone in an unfamiliar, alien world.

To me, at least, that is part of the fun...

Technical Data: Canon EOS 7D, Canon MP-E 65mm f/2.8 1-5x Macro, 1/250 sec at f/16. Canon Macro Twin Lite MT-24EX in ETTL mode. ISO 100. RAW processing in Adobe Camera Raw.

Obviously, this is a very close-up shot of an orchid. The way the light from the flash and the intentional "over"-exposure produce an unworldly realm - almost like some glowing cave to my eyes - really seems to draw me into this photo.

Super-macro Pointsetta

ktuli — Tue, 01/10/2012 - 22:42

At one point while trying out my new lens, I decided to take a series of shots with the different (albeit not all 5) magnification levels provided by the MP-E 65mm lens. In this case, I worked with the central flowering parts of a pointsetta....

Technical Data: Canon EOS 7D, Tokina AT-X M35 Pro DX AF 35mm f/2.8 Macro 1:1, 1/100 sec at f/16. Canon Speedlight 580EX II flash in auto mode and wireless control. ISO 100. RAW processing in Adobe Camera Raw. Phipps Conservatory, Pittsburgh, PA.

No - that photo is not a macro shot - I'm just providing it as a bit of reference. Some folks believe the red leaves (called bracts) are the flowering parts of the pointsetta - that's untrue. Some folks know that and believe that pointsettas simply don't have flowers - that too is untrue. What they actually have are fully male or female flowers (a single plant will have both), and they are contained in a cyathium - a flesh bulb similar to how a fig grows. So in the series below, we start with a 1:1 magnification of the cyathium cluster at the center of the plant, then move progressively to a 5:1 magnification of the (if I am getting my pointsetta anatomy correct) tops of the male flowers with the pollen.

Technical Data: Canon EOS 7D, Canon MP-E 65mm f/2.8 1-5x Macro, 1/250 sec at f/16. Canon Macro Twin Lite MT-24EX in ETTL mode. ISO 100. RAW processing in Adobe Camera Raw.

I think when dealing with this level of magnification, it is very easy to lose all sense of what it is you are looking at. Having the entire series of photos going through the magnification levels certainly helps to put things into a bit of perspective and provide some reference points to go on.

I'm really liking this new lens...

More Grains of Pollen

ktuli — Sun, 01/08/2012 - 22:07

I really should be posting more often, but I'm still kind in lazy mode from the holidays. Today is my last day off before starting my new job (yay!), so maybe getting back to work will start getting me back into a routine and have more frequent posts again. For now, enjoy another shot of grains of pollen... this time on a hibiscus flower.

Technical Data: Canon EOS 7D, Canon MP-E 65mm f/2.8 1-5x Macro, 1/250 sec at f/16. Canon Macro Twin Lite MT-24EX in ETTL mode. ISO 100. RAW processing in Adobe Camera Raw.

I think the spiky ball shape on this pollen is pretty impressive. I may have to collect a series of flower pollen shots showcasing all of the different shapes they come in.

Grains of Pollen

ktuli — Wed, 01/04/2012 - 09:36

I've taken some super macro photos of a pollen stamen before, but that was before I owned the Canon MP-E 65mm f/2.8 1-5x Macro lens.

This lens is a serious macro lens, and no other lens out there comes close to what it can do - which is to magnify things up to 5 times life size. Most true macro lenses will magnify up to life size (or 1:1), but the MP-E 65 can go way beyond that, allowing for magnification from life size (1:1) up to 5 times life size (5:1). I will get into more detail about that at a later date when I do a more thorough write-up of the lens, but for now that means you get to see what individual grains of pollen look like....

Technical Data: Canon EOS 7D, Canon MP-E 65mm f/2.8 1-5x Macro, 1/250 sec at f/16. Canon Macro Twin Lite MT-24EX in ETTL mode. ISO 100. RAW processing in Adobe Camera Raw.

Unfortunately, I did not record what magnification that shot was taken at, and I haven't figured out how to determine that after the fact yet. Regardless, that's still a highly magnified view of pollen - my guess is somewhere between 3-5x life size (probably closer to 5).

Stay tuned for more super macro photos...

Warm Glow and Seeds

ktuli — Wed, 09/21/2011 - 21:22

I had to dig deep into the archives for this shot, but as we head into autumn, this shot of these seeds and the warm sunset glow filling the whole frame, just really made me think of the colors and feel of a autumn sunset. To be entirely honest, this shot was taken in the dead of winter in December, but if it still gives the feel, who cares, right?

Technical Data: Canon EOS Digital Rebel XT, Tamron 180mm f/3.5 Di SP LD 1:1 Macro, 1/100 sec at f/8. ISO 400. No post production. McConnell's Mill State Park, Lawrence County, PA.

Speaking of going into fall, I have a hockey game to finish watching, so I'm off to do that...

Crab Spider on Dahlia

ktuli — Mon, 09/19/2011 - 21:05

Just another quick photo to share again today... I've been putting in a ton of extra hours at work, and it is just so mentally draining that it is having a physical toll too. Can't wait to get to this trip coming up and relax for a bit.

Anyway, it has been a bit since we've done a spider shot, so we'll take a look at a cool crab spider on a dahlia bud. I'd seen (and shot) several of these crab spiders this summer, and having this one on this richly colored dahlia was just so nice. I probably should crop it differently, but for now, here's the shot right out of the camera (with RAW processing of course)....

Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM, 1/250 sec at f/16. Canon Speedlight 580EX II flash in auto mode and wireless control. Image Stabilization on. ISO 100. RAW processing and cropped in Adobe Camera Raw.

I think after jumping spiders, crab spiders are my second favorite variety of spiders.

First Hummingbird Shot

ktuli — Sat, 09/03/2011 - 20:21

So we've managed to get a hummingbird to be a regular visitor to our yard this summer. So one Sunday morning after I got home from playing hockey, I noticed her stopping by the feeder and rose of sharon bushes. So I quickly went and got my camera with the Sigma 150-500 and my new tripod (have I mentioned that yet? I don't think I have! I guess I should get around to talking about that at some point, but not right now).

Anyway, I setup and managed to get just a few shots before she wandered off again and I had to go work on some bathroom tile repair work. Unfortunately, I totally did not think things through, and I used a rather slow shutterspeed of 1/30th of a second. Far too slow to keep such a fast moving subject from blurring.

But considering they were my first ever hummingbird shots, I kept a couple just the same...

Technical Data:Canon EOS 7D, Sigma 150-500mm f/5-6.3 APO DG OS HSM at 500mm, 1/30 sec at f/11. OS mode off. ISO 100. Raw processing in Photoshop CS5.

Sorry - no mouseovers for a cropped view on this one... it would just show you just how bad the blur is. At least at the smaller version, it makes it a little tougher to see the blur.

Hopefully I'll get another chance at this before the end of summer and she leaves for warmer climates... next time I'll know to use a faster shutterspeed!

Pollen Covered Sweat Bee

ktuli — Thu, 08/11/2011 - 21:44

Ok - sorry, just doing another very quick post today...

Technical Data: Canon EOS 7D, Canon EF 100mm f/2.8L Macro IS USM, 1/250 sec at f/16. Canon Speedlight 580EX II flash in auto mode and wireless control. Image Stabilization on. ISO 100. RAW processing and cropped in Adobe Camera Raw.

This is a green sweat bee (Agapostemon texanus) - for obvious reasons... well, at least the green part. I was quite happy that the shot captured the metallic qualities of this bee, and I was just drawn to the shot because of all that pollen covering its legs.

Thanks for stopping by.
