Olympus OM-D EM1 with 4/3rds 50-200 mm telephoto and FOTGA extension tubes

I am enjoying the FOTGA extension tube combo with my 4/3rd 50-200mm telephoto lens on the OMD-EM1. Below is a dragonfly I spotted sunning himself.





The FOTGA extension tubes add an additional 26mm extension (+16mm for the 4/3rds to micro 4/3rds adapter).

Nature Macro Shot Pet Peeve


I love all wonderful nature macro shots on flickr, G+, 500px, and other sites. I just wish more people would take the time to do some research and find out what it is they are photographing and add this as a caption or comment. If you are really interested in nature macro photography - surely the name of the species is important? You can use bug and plant identification sights on the web or get some field guides. I think the value of an image is lessened if the species name is not listed, no matter the wow factor of the image itself. The worst offense is to leave the image untitled. Really? You don't know what is generally? You can't tell it is a butterfly, ant, or grasshopper. A general name is better than nothing.

If you have tried to identify and can't, say so. Ask for help. Give some details about the image - where, how, when, what. Someone out there will know or have an idea about what it is.

Take a chance on the species name. If some one knows better and corrects you, Great! You learned something.

Once again, in my mind, the most spectacular image in the world is degraded if you don't know what it is.

Review of Nanguang 5400K LED Video Light Lamp for Camera DV Camcorder Lighting

I purchased 2 Nanguang 5400K LED lights for use with my DSLR from Amazon here. I received them very quickly. They are $20 lights, so I didn't expect much. They lived up to expectation. They are very basic units that are not designed for durability. I had to disassemble one unit to replace the on/off dimmer knob which had come off. Fortunately the tiny screw used was still inside the unit. While I had the unit apart to replace the knob one of the wires broke so I had to resolder it. Crappy build.

Pros: Cheap, good light, accepts AA cells, hot shoe mount
Cons: Cheap build, very fragile - not professional quality at all.

I already had a Sima  led light for my camera. The design and build on it were much better.

Ok for occasional use.

Velbon Super Mag Macro Tripod Slider and Focus Stacking

I have been wanting to do some focus stacking images for some time. Particularly for the flowers I like to photograph. I cannot get the whole flower (petals, stamen, and pistol) in focus with one shot. By using focus stacking you can create an image which will have the entire flower in focus. Find out more about focus stacking here and here. To make this process easier, I purchased the Velbon Macro Tripod slider like the one shown below:



Here is Velbon's description: 

The Velbon Super Mag Macro Focusing Rail Slider, essential for precision macro photography, is made of a lightweight, corrosion-resistant magnesium alloy. Even with a steady hand, macro photography can be tricky and temperamental. The fine tuning of the Super Mag Slider helps you find the right depth of field to take precise close-up photos.
The smooth action macro-rails consist of X and Y movable tables for precisely adjusting focus. The X axis moves right and left, the Y axis moves towards and away from the operator on threaded rods. By using the included allen wrench you can separate the top and bottom tables for additional modification. Underneath the top table (Y), there are both 1/4 and 3/8-inch threaded holes for mounting the top table to a tripod. The adjustment knobs are smooth and fluid, and have just the right amount of resistance.

  • 4-way adjustment - forward / backward / left / right
  • Detachable lower base - changeable to 2-way slider
  • Made from light weight & durable magnesium alloy
  • Lateral adjustment rang: 1.2" (30 mm) / Fore/aft adjustment range: 2.4" (60 mm)
  • Dimensions: 8.3 x 4.7 x 2.8 in. (210 x 120 x 70mm) / Weight: 1.04 lb. (470g)
I completed my first attempt at focus stacking using a cone flower. I took 17 images turning the rail advance screw about 1 turn each time. Here are the 17 images and the result.




 I used a program called  Combine ZP to align, scale, and stack the images. It is a free program that works remarkably well.

The Velbon unit worked well. I only wish that the X and Y movement knobs were on opposite sides. They can be made that way, and I will make the effort. More than once I had to start over because I moved the X position instead of the Y position. Here are my camera settings:

White Balance - Manual
Shutter Speed - Manual - 160
Aperture - Manual - 2.0
Mirror up delay - 5 secs

I started where the center (Highest point) of the flower was in focus and moved in in 17 increments. I mounted the slider on my ballhead.

This exercise was just that - an exercise to see how to do the setup and use the software. The Velbon slider is a vital part of the setup and it performed very well. I can also recommend the Combine ZP software.

More on the Fujifilm F505

I have had the F505 for a couple of weeks now. Here are some pros and cons:

Pros:

1) Panorama setting is really really cool.
2) The camera can capture 3 continuous shots in one shutter click for HDR shots. The shots are set to under exposure, normal exposure, and over exposure. The amount can be set at 1/3, 2/3, or 1 stop. Way cool.
3) Macro function and the closeup ability of this camera is outstanding.

Cons:

1) Mode button is easily moved by accident
2) Buttons are tiny
3) Barrel distortion on full zoom
4) Slow image storage - you have to wait on the camera after 2 shots
5) Oversaturated colors - particularly the reds
6) Overall image quality
7) High ISO images are quite soft

There are still functions I have not used. I am still finding new ways to use this camera. In spite of the flaws, it is well worth the $150 paid.

How I used a glass ball (orb) for macro photos

I used a glass orb with a wire stand to make some interesting macro photos of a snail shell. You can see the images here. Below is a diagram of the setup. I used coat hanger wire to make the stand.


I got my 80mm orb from an Amazon reseller.

Closeups with Glass Orb

There is a group on G+ that features images taken with a glass ball or orb. It's called #oculusimages. Most of the images are landscapes and they are pretty cool. Well, the orb can magnify as well. So I used it as a magnifying glass for photographing a snail shell. I really like the images. I love have the light diffracts and the blur. Kind of like a lensbaby, but more versatile. I made a little stand for my orb and put the shell underneath it. I lit the shell with a flashlight. I will definitely be playing with this again.

Tip for Cleaning Flowers for Macro Photography

I have often used a soft brush to remove bits of dust and dirt from flowers prior to making closeup photos. Another good tool for this is canned air. I like the #M brand, called 3M Dust remover because it has a trigger mechanism which controls the force of the air. This way, you do not damage the flower when removing dust and dirt.

Macro using Reverse Mount Lens Adapter

Last week I received a reverse lens mount adapter for my Zuiko 35mm f3.5 macro lens. I tried it right away. The way it works is this: You are able to thread the adapter to the outer filter threads of the macro lens. Then you flip the lens and attach the adapter to the lens mount on the camera. By reversing the lens, you get more magnification. Here's a sample photo of a small spider. I realized right away that a non-moving target is a must.

Also, a tripod will be necessary for the best shots. This spider was shot holding the camera by hand, and it was difficult to control. The DOF is very shallow. Also, it becomes more important to hold the camera lens parallel to the plane on subject that you want in focus. But, it shows a lot of promise. I will be able to get magnification that I was unable to get before. With patience and practice hopefully I will get some decent images. Here are some links at DPReview that deal with the subject. I'm looking forward to working with this setup to get some interesting macro shots.

Using a LED Head Lamp as Macro Light



I am always looking for ways to light up my macro subjects. I recently saw a 12 Led headlamp at the local Walgreen's. The cost was only $5.99. I thought this might somehow be adapted to the camera for a little bit of extra light for macros. I was able to use the existing elastic band that came with the light to attach it to the camera. The angle of the light is adjustable so you can aim it at the subject. It doesn't add a tremendous amount of light, but it does make a difference. Sometimes the difference can be between getting a shot or not. I'll add this to my bag until I get a ring flash.
