Polarization in Macro Photography

Eupholus weevil dancing

I am occasionally asked how I come up with topics to discuss during my twice weekly livestreams. The topics come from several different sources. Most often, I am answering a question that was brought up by one of my students or asked by a livestream participant. If, when thinking about the question, I can expand on the topic to include interesting background and details, it will often become my subject for the week. But I also keep an ever-growing list of promising subjects that occur to me during my own exploration of macro photography and associated disciplines. The beauty of macro photography is that there are more fascinating topics to explore than I could cram into a lifetime of livestreams.

I try not to repeat myself and avoid talking about the same topic twice in the same year, and even when I do return to a previous conversation I try to emphasize information that has not been covered. I need to bear in mind that new viewers are going the streams every week and for many of them this may be the first time they have encountered the topic. Balancing the needs of the newcomer to macro with the seasoned experts that  are also in the audience every week is the hardest part of programming these events.

This week, for example, I am breaking from my usual practice of finding a common theme for both livestreams and instead will be addressing two distinctly different topics that came up in conversation over the preceding week. This has the advantage of keeping things interesting and relevant to more viewers, while keeping the process interesting for me at the same time.

On Tuesday I am going to  talk about the use of polarized light in macro photography. I don’t think I have ever discussed this subject as I plan to in this livestream. The question that prompted this was a practical one - “when should be using  polarizing filters in macro photography?” - and to answer that I need to explain a little about polarized light. So I will open with a discussion about light in general and the concept of polarity in the context of visible light. When we understand the nature of light and see how it can be polarized, everything else I talk about should make a lot more sense. For example I will explain the difference between using a polarized light source and polarizing the light that enters our camera through a polarizing filter. When do we want to use the former, when the latter, and I will introduce the concept of using both.

For a subject to be useful for your photography it needs to have some practical application, so I will describe the various types of polarizing filters and give step by step recommendations on how they are used. By the end of the hour you should have everything you need to make wise decision about when and how to use polarization as well as information on the best brands of polarizing filters to look for. B&H carries a wide selection of the very best circular polarizing filters - you can find them here - https://www.bhphotovideo.com/c/search?Ntt=circular%20polarizing%20filters&N=0&InitialSearch=yes&sts=ps&BI=23366&KBID=28903&SID=DFF&DFF=d50

On Thursday we are going to look at something completely different that I think should be of interest to many of you. What is the best tripod head for use in macro photography? I don’t think I have ever talked about this in any depth but it is quite interesting. For one thing, there are a lot more options than most people might be aware of, and they are not all equally ideal for close up work. I will describe all the different ways in which a camera can be mounted to a tripod (monopod, ground pod, camera stand, etc.) and discuss the relative merits and drawbacks of each. Based on my own experience I will make specific recommendations for each time of head and explain why I use each of them.

The amazing magic ball from novoflex

If you are thinking about adding or replacing a tripod head in your bag, here are a few of the products that I recommend and will be talking about during the livestream.

my favorite benro three way geared head

When it comes to ball heads you will have a hard time finding anything more versatile and well constructed than the Really Right Stuff BH55, available from B&H - https://www.bhphotovideo.com/c/product/1301057-REG/really_right_stuff_bh_55_pro_bh_55_ballhead_with_full_size.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x781162/SID/DFF

Another contender at the top of the stack is the incredible Novoflex Magic Ball - a different take on the ball head but one that many of the best macro photographers swear by - https://www.bhphotovideo.com/c/product/153279-REG/Novoflex_MB_Magic_Ball_with_Socket.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x1596924/SID/DFF

A gimbal head form sirui

For the more budget conscious photographer, Sirui makes a really lovely low profile ball head, the AM40 that is a little smaller than the RRS, but a lot less expensive - https://amzn.to/4hfVBVG

A quality fluid head from neewer

In the geared head category you will not find a better affordable three-way head than the Benro GD3WH that I use. I have ben using this for at least 6 years and I love it - https://amzn.to/3AaA93v

the perfect head for macro on a monopod

Another option if you jus have to have the best geared head on the planet is the original Arca Swiss cube, available from B&H - https://www.bhphotovideo.com/c/product/1373798-REG/arca_swiss_8501303_1_cube_c1_gp_geared.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x861127/SID/DFF

I think a very fine alternative at a lower price point is the new Leofoto geared head, also from B&H - https://www.bhphotovideo.com/c/product/1796458-REG/leofoto_gw_01_3_way_geared_head.html/BI/23366/KBID/28903/DFF/d10-v21-t1-x1340748/SID/DFF

not strictly a tripod head, I like to use this leveling device for still life work

For anyone wanting a video friendly fluid head, a very attractive option is the new Neewer, shown above. It is sturdy and easy to use, while also being very affordable - https://amzn.to/3YcPZmo

The SmallRig DH10 is another excellent choice - https://amzn.to/4f3DvEm

I recommend a two axis head for use with a monopod and one of the best for the price is the Sunwayfoto DT-03S - https://amzn.to/3BTe0HA

B&H has a wide selection of other monopod heads - https://www.bhphotovideo.com/c/search?Ntt=monopod%20head&N=0&InitialSearch=yes&sts=ps&BI=23366&KBID=28903&SID=DFF&DFF=d50

Planning Ahead

Studio starting to look a lot better!

Summer is half over andI have no idea where the first half went - but I have a feeling the second half is not going to go by any slower. So this probably the perfect time to start thinking about the rapidly approaching “off-season” for insect photography. If you, like me, want to plan for a productive winter in the studio, the time to do so is now. For the first time in many years I have had to come to grips with the reality of an honest to goodness winter season - and I am not talking about the kind of winter that I am used to - the kind that consists of a week or two of temperatures in the mid-fifties. In just a few more weeks I will be faced with some of the harshest winter weather that the North American continent can produce. The Midwest is well known for its long, cold, wet ,and windy winters, with heavy snow and sub-zero temperatures being absolute certainties.

Every year, in the early fall, I will devote a little time to talk about the changing seasons but it has always been with a sort of academic detachment - like I was describing the conditions one might expect to encounter during a visit to one of Jupiter’s smaller moons. This year I feel a slightly greater sense of urgency and have decided to tackle this question both earlier and more thoroughly than I have in the past. And with this in mind our preparations for the coming winter kick off this week with a two part livestream titled “Planning Ahead”.

In  Part I, on Tuesday July 23rd, I am going to lay the ground work for a series of more detailed and specific discussions that will deal with exactly how we can get the most out of the coming winter. In this first session I will talking mostly about the things we can do to  extend the insect photography season, though later on I will  be getting into several other macro disciplines that also require some careful planning. Here are a few of the specific issues I will discuss on Tuesday:

Setting realistic goals

Making a “Catch List”

Dry cleaning vs. wet cleaning

Pre-posing cleaned subjects

Dealing with eyes

The importance of maintaining an up to date “catch catalogue” and shooting schedule

Stocking up on supplies

Planning for bycatch

Dealing with soft bodies and the role of taxidermy

Storage for shipping vs. storage for shooting

Live storage

Never wet and never dry subjects

Avoiding stress

Chemical consequences

Purchased specimens and the difference between commercial drying and home drying

Size matters

Don’t forget the background

To Kroil or not to Kroil?

Sounds like a lot to cover? It is - but that is why I am starting this discussion earlier than I have done in past years. And most of these topics will covered separately and in more depth in future livestreams and video presentations. But for now, here is your invitation to the livestream… https://youtube.com/live/J3aulAGOWDI?feature=share

The first of these deeper dives  will be presented on Thursday when I get into to the very practical matter of pre-shoot temporary storage of posed and unposed specimens.

This is a subject I have not previously presented at such a granular level, but just exactly how do you store cleaned and posed insects for future photography? In this stream I will show you the storage methods that I personally use and I will also show you exactly how I make the storage vessels I prefer. Think of it as a mini-DIY tutorial  - easy to do and extremely helpful. Here is your invitation to the livestream… https://youtube.com/live/YDUkWV0kg0w?feature=share

If you are waiting for the recording from Saturday’s  Pzoom livestream, it is posted over on Patreon - and it was a good one! I have also posted a copy of the chat, which is packed with useful links and other cool information.

But if you are waiting for the release of the “Tangent - 3D modeling livestream”, it was released today and can be seen by following this YouTube link, or you can simply click the video link https://youtu.be/L2r4ziTplXo, and just watch it from here…

This is a non-Pzoom weekend coming up, but that means it is time for another “After Stack” post-production workshop and roundtable discussion with Bud Perrott and yours truly.

This week we are going to be taking a closer look at all the different ways that we can refine masks in Photoshop and other non-destructive phot-editors. If you have not come to one of these events in the last, this would be a great time to change that as this promises to be an extremely practical and helpful session for anyone doing their own macro photography editing (in other words, for everyone). Don’t miss it - Saturday morning at 10AM. This is a Zoom event so you will need a copy of the invitation to attend - and here it is -

Allan Walls is inviting you to a scheduled Zoom meeting.

The July Macro Competition is wrapping up next week, so if you have not submitted your entry for the month you need to be thinking about getting that done before NEXT THURSDAY! The theme is “It Came from the Grocery Store” - a macro photograph of something you could find at the local grocery shop - shot at 1:2 or greater magnification. You can submit up to two images unless you have previously won this competition, in which case you may only submit a single entry. Harold Hall is my guest judge for this event and I am really looking forward to this one!

Lastly, I am trying to get a headcount for the upcoming “First Annual Midwest Macro Picnic and Livestream” - if you are interested in participating in a free, live, wide-angle macro workshop, somewhere in Illinois during the first or second weekend of September, you need to let me know how many people you are bringing and where you are coming from (so I can choose a venue that is maximally convenient for everyone). You can message me through the Walls App (https://www.walls-app.com) or the Patreon messaging system, but you need to do it right away - I have a lot of arrangements to make!
