During the London Dive Show I attended a talk from Martin where he covered a number of shooting situations and how to deal with them in terms of composition and settings.
There was a promotion for a two for one tuition day with him that my buddy was keen to take so few months later we made our way to Dorset for a day of underwater photography with Martin.
This will be my first day of shooting with the RX100 Mark II albeit in a pool with my new arms and lenses so I was looking forward to it.
We arrived in Poole the night before and got ready for an 8.30 start with Martin.
We started off with a review of some basic exposure concepts and then looked at competition winning pictures and trying to identify what makes a wow picture. It was extremely useful!
Afterwards we went through our trips pictures so he could see what needed improving. Then look at what was needed for the next trip.
With that in mind we set up to jump in the pool to take some pictures the objective was to improve my buddy close ups and portraits as apparently her wide angle is as good as it gets with the Canon S95 used see featured image on this post.
Pool conditions were low visibility and plenty of suspended particles as the pool is used for kids swimming lessons let me give you an idea!
The first task was to shoot a frog with a view of eliminating shadows in its mouth. Start with one strobe and finish off with two.
The frog with the bare port gives you an idea of the size and the complexity of the task with one strobe. There are shadows in his mouth.
I then shot a portrait at 50mm, the reason why you see shadows more on the left is because I set the strobe at different powers.
The magnification of the RX100 is little so I went on with a first Inon UCL-165 and full zoom at 100mm equivalent. Note that everything is pretty much sharp at f/11.
With two Inon UCL-165 focusing on the mouth will result in this and the eyes being in focus and the rest blurred because of lack of depth of field.
I then moved to an Octopus rich of textures. I took the first shot with my Inon UWL-100 28AD with dome.
The same octo at 28mm fills the frame much more of course.
The Octopus at 50mm looks even better. I have topped up the lighting on this one.
I then took this guy with a single UCL-165 note the depth of field insufficient to keep the back of the head in focus, results though are exceptional.
With two close up lenses we go back to the depth of field problem even at f/11.
I thought I had at that point nailed all focus and strobe issues, especially considering I shot with single auto focus, I did not bother using manual focus at all with exception of some double diopter shots.
I then tried a few surface reflections with the fisheye this being the best.
You can see the outside of the pool and the windows on the top.
Afterwards made my own composition of statues for a fisheye shot that I think came out very well. The Z240 performed extremely well in both TTL and external auto as well as manual.
Martin asked me to have a go at the child with the dog as it is extremely difficult to lit up properly.
I went for an alternative strobe placement with light from the bottom as if it was in a gallery. He was impressed with the results.
To finish off my last task was the tongue and eyes of a lion that I shot with a single UCL-165.
Overall a great day and I definitely recommend you the tuition day with Martin. He is a great person and extremely good at teaching I can see the benefits my buddy had right away.
Lessons learned on the RX100
There were a few things that I learned about my RX100 still rig mode that I want to share with you.
- The autofocus is incredible. I even used this for macro. If the camera does not focus is because you don’t have enough depth of field and that is it.
- Best macro performance is with a single diopter and also had a benefit of an increased working distance, this means the shots will need cropping for extremely small critters
- Two diopters resulted in near bokeh with less than 1mm in focus and difficult to autofocus (though the LCD is great and I could see if things were in focus or not I think this is personal and I would recommend DMF to others)
- Performance at wide angle with the UWL-100 28AD with dome is stellar
- Inon float arms (I used two 6″ segments) were perfect with lens holders on it.
- Inon Z240 twin set with one in TTL and the second in external auto delivered creative lighting without headaches, remember to buy the AUTO diffuser that does not come with the strobe
- Strobes in manual allowed for even more creativity and the level of precision compared to sea and sea was staggering
- Despite pool conditions the RX100 focused well in low light and much better than the Canon S95 that was returning focus error on the same exposures. I will not bother having a focus light with this camera and only have a single sola on night dives
