Hairy Octopus Video

I finally got around to posting my Hairy Octopus video, we’ve seen 3 in 3 days now here in Lembeh!

Tangkoko Tour

Visiting Tangkoko National Park is a fun way to spend an afternoon when staying in Lembeh.

The highlight is obviously the Tarsier, a minute primate that loves to eat grasshoppers and nocturnal insects, Tangkoko is famous for it’s Tarsiers and Black Macaques, but you have to go earlier to see the Macaques and i’m always late!    We actually have a very healthy population of Tarsiers  living around the resort and on a good night you can hear more than 15 of them squeaking away (this is probably bad for the Tarsier as they only shriek when a family member is missing).

On the Tangkoko tour you can also see Black Macaques, and sometimes Hornbills.  You will need mosquito repellant and comfortable shoes, and probably a raincoat if you’re unlucky!

Johan, Marnes and Indra shoot their first Hairy Octopus

We’ve been having fantastic diving recently, and we have been having some fun with the guys taking pictures and also annoying out yearly repeat guest, Mood.
Mood has been to Lembeh every year for the last 5 years and still does not have the hairy octopus, he always missed it.  We see it when he has a bad ear, when he skips a dive, or they find it on the same dive he is on but he has gone off looking for something else and is too far to call over.

The other day the boys took me to try to find the Hairy Octopus for the first time, and they found one on each of the first 2 dives – they haven’t found one for a while so there was quite a lot of excitement, and obviously a lot of bravado beforehand, and even more afterwards.

I was pretty amazed by this creature, so i thought it only fair that I let them click off a few shots whilst we were waiting for the guides to find Mood.

Here are their shots!

Some photos from the last week

I started the week diving a lot, but with routine engine servicing (7 engines over 2 days), new restaurant furniture (pics to follow soon) and removing a flower bed and preparing for the final phase of the roof renovation (above the wet camera room) – I am heading into the weekend feeling I haven’t dived enough, even though i have dived more times this week than i did between September 2011 and September 2012!

The diving highlight for me was finding a strange shrimp all by myself and experimenting with lighting on a few critters.  The big downer was missing some cool  sightings such as the 3 bluerings on this afternoons dive.

Photo tips: Bracketing

I touched on bracketing in the previous photo tips post.  Bracketing was used (back in film camera times) to make sure that one of your shots from a sequence was correctly exposed;  you take a sequence of shots at varied settings and hope that one was correct.

As an example – if you set your camera in full manual, and at f/8 and your meter reading told you to use 1/60th, then you’d shoot one at f/8 – 1/60th, one at f5.6 – 1/90th and one at f/11 / 1/30th (back then we didn’t have 1/3 stops).  This was based on your strobe power being correct for f/8, from the table printed on the side of strobe.  By using varied f-stops you could manipulate your exposure, and maintain the same background ‘blue’.  Those days are gone so there’s not much point in going back through the nostalgia of developing your film and spilling chemicals all over yourself, so don’t worry if you don’t get all that right now – if you shoot manual for long enough, you will understand it.   In our modern iworld we have digital and it is supposedly easy.  Except you have to organise everything (that blog post will come when I’ve worked out the best way to be organised, which isn’t going to be anytime soon) and these days we tend to just expect things to work, sadly this isn’t the case for underwater photography, it needs human input to flourish.

Bracketed Frogfish

These 4 shots were bracketed with strobe position (lowest power setting). This gives different shadow positions. I checked after every shot so I can remember which shot had which position. No 4 was my favourite, so i stopped there.

To be completely honest, Bracketing in the sense outlined above is pointless in the digital era, you have a screen on your camera and you can check – so you don’t really need to shoot all these combinations of settings for each subject.  If you did the above for 5 minutes on a piece of rubble at the distance you normally shoot a subject from (it doesn’t normally change much in Lembeh) you will know the setting you need to start from for almost every dive here – that’s your benchmark setting and everyone has one. I actually have 4 benchmarks depending on the setup:

  • DSLR, TTL Strobes, working distance 5 – 15 cm:     ISO 160 :: f/18 :: 1/100th, flash ev -2/3 (on camera setting).
  • DSLR, Manual Strobes, working distance 5-15cm:  ISO 160 :: f/18 :: 1/100th, 2 flashes set to 1/2 power
  • Canon S95, manual settings,  working distance 5 – 15cm:  ISO 100 :: f/8 :: 1/100th, flash set to 1/2 power
  • Canon S95, Aperture Priority, working distance 5 – 15cm: ISO 100 :: f/8, flash set to ttl and camera set to -2/3 ev.
Bracketing Coral Scenes with F-stop

Bracketing Coral Scenes with F-stop, F/10 on left, F/13 on right, everything else constant.

What we have to bracket these days if we are shooing auto or semi-auto is different effects: different lighting angles, different coloured backgrounds (exposure), different depths of field. Very rarely should you be bracketing exposure whilst shooting a subject on a macro dive.  If you are spending ages bracketing your exposure on a pair of mating bluerings whilst other people wait, something is wrong. Same applies to Pygmy Seahorses, practice on the fan with no pygmies to get your settings somewhere near correct, and remember what you did for the photo that turned out good.

I think what is key to take from that ancient era of bracketing, is the mentality.  You never trust your camera, you fully expect it to not be perfect and that you, the user, has to make it work.  In the old days, bracketing 3 shots from your max 36 was quite a commitment. That would give you 12 subjects in a dive with 3 shots per subject.  You had 2 choices, blast away and never get any better because you had no idea why the shot was good, or put some effort in.  This is the other important thing to take from the old-timers.  THINK BEFORE YOU SHOOT.

There’s nothing cool about taking 100’s of shots of the same animal.  An underwater photographer hopefully will not blast the heck out of a subject because they have a new set of batteries and a 32gb card, I’m not saying don’t use a flash; just think about bracketing on something not too fragile first if you are not confident with your settings (try taking 20 flashes from your underwater strobes with them 10cm from your face – i bet you stop at 3). A good underwater photographer will look at the subject and think first.  If the positioning of the critter isn’t good, then it might be best to move on – think back to your library of images, do you have a better one of that same subject already?  Try this as a routine:

  • Angle of approach to the subject
  • Metering / camera settings
  • Strobe positioning
  • Strobe power
  • Pull trigger

This still applies these days,  taking those 5 steps to make sure all your settings are good makes you cool in my book.  I say that with humour but I mean it, it is genuinely cool watching a seasoned pro select the subject angle, tweak a few things, take a photo, tweak again, shoot again, and move on.  They got to that level by pushing themselves to remember settings and techniques.  They used their brain and read books.

Bracketed Banded Pipefish

Bracketing a Banded Pipefish with strobe power, shots i would not have attempted with film unless I was very bored.

From my example photos you can see I have bracketed on a subject, but it is a variance of less than 1 stop, so all of them are useable because I shoot raw format and you can tweak them in the computer.

If we are to re-jig those 5 bracketing options from the old days, and say like most people you are using automatic strobes and can get the correct exposure to within editable standards then that leaves these 3 options:

  • Angle of approach to the subject
  • Strobe positioning
  • Pull trigger

Obviously the 3rd one is quite simple (or is it?).  The first 2 will be the subject of my next blog post.

Photo Tips: Introduction

With everyone shooting digital and huge memory cards it is quite easy these days to take 100+ photographs in a dive, especially in Lembeh.

The key to getting a good photo that you are still happy with by the time you go home is to take your time and keep using the image review button.  Here at NAD we have started to make a recommendation of take 5 photos, nice and slow, then pass the subject on to someone else if they are waiting.  Whilst they take their 5 shots you can take a look at what you shot and find the problems and try to correct this for when the subject gets passed back to you.  This was brought about by a bunch of serious photographers agreeing (our stand in blogger, Bent, was one of them) to be more civil to each other in this way, and they actually found that they ended up with better photos than had they just blasted away for several minutes.

In the old days of film we were always taught to bracket, as it may be weeks before you get to see your developed pictures – so take several and pick the good one later on.  So you would bracket your exposure, and sometimes your strobe position.  Writing down the frame number and technique on a slate, then transferring it to a book back on the boat between dives.  Fast-forward to getting your slides back a week later you would check each slide, hoping that your numbering came through and find the best one and check what you did in the book, and try to remember it.  Very tedious isn’t it?

With these digital cameras to do all that, instantly, all you have to do is press the ‘play’ button to look at it straight after you shot it.  So my question is, why are some people too lazy to do that?!

There really isn’t much excuse for saying at dinner, “my shots were all bad, I need to go back to that divesite again” – unless you had malfunctioning equipment or a malfunctioning buddy kicking up silt in all your photos.  Going back to a divesite because it was orgasmically good, is of course a completely normal excuse!

I will admit of course I have done the above myself.  Getting caught in the moment and not checking the image review and then coming back with a memory card of junk photos where a strobe was out of battery, iso was set to 6400, etc etc

There is a big difference between shots not being good enough, and shots being just plain bad; if they are plain bad, you need help, probably a course.  Either  a quick freebie refresher from me to make sure your camera is working properly (free means a quick 20 minute run through 😉 Not me looking at every out of focus picture you took), or maybe a paid course with me where I come diving with you and watch what you are doing.

If  you are reading this and nodding your head repeatedly at all the mistakes  laid out above, you might want to do a workshop with someone like Mike Veitch (he has a workshop here next year). People like Mike (I used to work with Mike on these workshop weeks in the past as well) do these intensive weeks of tuition where that’s all it is about, learning – no other distractions.  Now I have a resort and a baby so my time is more limited. So if you really want to learn a lot I totally recommend coming to the Underwater Tribe workshop in April.  Mike and Luca will just be teaching, they wont dive with their cameras, their focus will be on you.

I will be blogging about some techniques and tips over the next few weeks leading up to our Photo Competition that might be of help to some of you. They might also be useful for the experienced photographers out there as well, as a good photographer is always learning – I find myself learning to shoot all over again after a few years of being ‘dry.’  My first post will be about Bracketing, and will be coming soon…

Dragon Shrimp

The Dragon Shrimp (Miropandalus hardingi) usually lives on whip corals and is quite a rare critter in Lembeh, although at the moment we seem to have a lot (and a lot of everything in general!).  It is not a very exciting animal, so my video is quite short, it did move a little bit so there is some ‘action’ in there.  I shot this selection of clips and images whilst giving Stenly and Johan a dive as part of their photo courses.  Stenly shooting the 7D and Johan with the S95.
