Bee Flies

I'm a bit slow updating this blog but I will try to keep it ticking over. Here are a few images of a Bee Fly feeding on flowering redcurrant in my garden from back in the spring.

I may have mentioned previously that I'd never seen Bee Flies in and around my Leicestershire patch at all until I moved 13 doors up from my previous house and have now had them in my garden for 2 years running! They're amazing looking insects. These images were taken handheld using a Canon 1D mkIV with Tamron 60mm macro lens and an MT-24EX flash.

Photomicroscopy: Different image styles

I mentioned in a previous post that I have been using a microscope quite a lot in recent months and have been very much enjoying taking different styles of photograph. I was playing around with some images earlier and thought I'd put them together in a composite to show just some of the different optical techniques that are used within microscopy and how they can result in quite different looking images.

The subject here is a type of rotatoria, a tiny aquatic organism. This one is 0.3mm wide and in each photo it has been photographed at 160x magnification using an Olympus OM-D E-M1 and a Zeiss GFL microscope.

The top left image is taken using a technique called Variable Amplitude Contrast (VAC), top right was taken with traditional brightfield, bottom right was taken using phase contrast and bottom left was taken using darkfield.

The same subject, the same camera and microscope, but 4 different ways of viewing the subject which all result in very different looking images.

Outdoor Photography Article

I'm very pleased to have a 7 page guide to insect macro photography in the latest (May) issue of Outdoor Photography magazine.

The article provides some pointers on learning about your subject, technique and composition, using flash and wideangle macro. There's also some info on equipment.

Microscopy

Having had a long-standing interest in insect macro photography I have often been tempted to take the next step and to examine and photograph microscopic life. However one of the main reasons I didn't was because of my erroneous belief that there was little scope for creativity in photo microscopy or much potential to take different styles of photograph.

Back in the Autumn I was very kindly given a book on microscopy which made me realise that, actually, there are a variety of ways to photograph microscopic life and plenty of scope for different lighting and other photographic techniques. Fast forward a few months and quite a lot of background reading and I became the proud owner of a 1960s Zeiss GFL microscope stand with a trinocular head (meaning a camera can be attached without having to remove the binocular eyepieces) and a selection of good quality Zeiss objective lenses. Although a vintage model (and older than I am!) the Zeiss GFL that I bought is in excellent condition, is superbly built and works as well as the day it was made. It also has very attractive 1960s styling which provides a nice contrast to my Olympus E-M1 which I can connect directly to it.

A benefit of my Zeiss GFL is that it is capable of three different styles of image: (1) is 'standard' so-called brightfield where the image has a white background (2) is known as dark field where a black background is achieved and the subject is side lit which provides a very different image to bright field  and (3) so-called phase contrast which provides a pale to mid grey background and the subject is normally shown with a lot of contrast which helps to pick out detail.

An iPhone image of my Zeiss GFL with trinocular head and Olympus OMD E-M1 attached. Note that I also connect the E-M1 to my iMac (which also sits on my desk) and can view the image directly on the iMac screen. This makes fine focusing much easier.




I have bought a number of prepared slides to view through the microscope, some, unbelievably, dating back to the 1860s, and have also made some of my own (temporary) slides viewing the life in standing water in my garden. It's a bit of a cliche but microscopy really does open up another world and I've very much enjoyed building my knowledge and skills over the last few months - though I still have a lot to learn.

Below are some of my favourite images taken so far.


Pine pollen composite, Zeiss GFL, 400x, darkfield, most were stacked
 from 2-4 frames in Zerene Stacker (ZS)



A section of a young pine cone showing individual pollen grains, Zeiss GFL, 100x, 
2 shots stacked in ZS, darkfield

An individual diatom (a type of microalgae with amazingly detailed shells). Zeiss GFL, 400x, Phase Contrast and stacked from 6 frames in ZS

An individual radiolarian (a type of microscopic protozoa, again with amazingly detailed shells). Zeiss GFL 400x Phase Contrast, 20 frames stacked in ZS

Marbled White Butterflies

The summer feels a distant memory but here are some images of a trip to Ryton Wood Meadows from back in July. This site is always good for Marbled White butterflies and so I try to manage one visit per year given the lack of nearer Marbled White sites.

As usual, I was keen to include the butterflies' habitat within the images so used a combination of my Laowa 15mm macro and Tokina 35mm macro lenses for many images.

The first is perhaps my favourite image of the session (Tokina 35mm):



I was lucky enough to find a mating pair of butterflies. This image was taken with the Laowa 15mm lens:



while this came from the Tokina 35mm. The breeze had got up by this point was was catching the butterflies' wings:



here's a more conventional shot taken with my Tamron 60mm lens:



finally, here's one taken with my Olympus O-MD E-M1 and Olympus 60mm macro:

Spiders in BBC Wildlife Magazine

I'm very pleased to have a couple of images, including a double page spread, in the October issue of BBC Wildlife magazine illustrating Adam Hart and Anne Goodenough's article on House Spiders. One image is a close up of a House Spider's eyes, the other (the double page spread) is a wideangle image of a Tegenaria sp. spider in my kitchen (using my Laowa 15mm macro lens).

Here's the uncropped version of the image:



and here's a few more from the same session:

BBC Wildlife Magazine Ladybirds

Over the years my images have been published in a variety of different magazines, books and newspapers but there's no doubt that I get the greatest satisfaction from seeing my images in BBC Wildlife magazine. I'm therefore very pleased to have 3 images in this month's (August) issue all illustrating Helen Roy's very nicely written article on Seven-Spot Ladybirds. I'm particularly pleased that one of them is in the form of a double page spread. Below are iPhone snaps of a couple of the images.
