#345986 Physically small intervalometer

Posted by Paul Kay on 10 April 2014 - 12:49 PM

Hey Paul, I have a few questions for you if you have a moment:

 

1. How did it work for you?

2. Obviously you would have to set it before you close the housing, how did you control it?

3. Does the trigger button control when it starts and stops?
4. Has anyone tried Magic Lantern's TL?

 

I have 3x 7d's that I would like to experiment with, but I would like a more secure method with my 1DX. Thank you ahead of time for any information you can provide.

1. Worked fine on a 5D2

2. Yes preset it and accept some 'blank or irrelevant images'

3. On the Canon intervalometer its the 'start' button I think (I'll have to dig it out from the box its stored in if you want me to check, but its fairly obvious).

4. I haven't - looks like others have.




#340809 BBC Natural History Request

You could try asking them to 'swap' it for a piece of 'similar quality' footage and request the same rights over it. I'll bet they don't go for it though......




#335832 Glass Dome Port Repair

Posted by Paul Kay on 15 August 2013 - 03:22 AM

Glass usually require special polishing and the problem is that grinding the damage away effectively can lead to heat build up which can shatter the glass - I know! But it is as you say, worth a try - find a glass repair specialist if you can.

 

Why not ask the Aquatica about it? It may still be cheaper to have a new glass dome fitted than repace the whole port.




#332432 Animal movies: Should they be real or embellished through artistic license?

Posted by Paul Kay on 05 June 2013 - 11:51 PM

 I guess  the question is whether movie magic should be reserved for fiction, and natural history documentaries should endeavor to retain a certain sense of truth.

As I see it, the problem IS defining truth. There is often an emphasis on filming 'rare' or previously unseen/unrecorded events in documentary film making. This in itself skews the viewer's perception of the natural world, as do many stills photographs. We seem to live in an increasingly 'virtual' world (laser pistols were used at the Olympics instead of air pistols as an example - do they really form part of a physical sport I wonder?) and the lines between fact, representation and fiction are IMHO blurring more than ever. I suppose my take is that if it does some good and it raises profiles and safeguards and allows animals to get on with living in the wild, then so be it. Claiming any natural history documentary is 'true to life' is actually quite difficult as any editing will form an impression in the viewer's mind which is potentially distorted by the condensation of time if nothing else. I suppose that claiming 'true to life' is where the dishonesty can appear - films and documentaries are all representational at the end of the day and it is important to appreciate this when viewing them and enjoy them for what they are.

I imagine that this will be challenged in the EU as it will affect many non-UK photographer's too and will undoubtedly enrich lawyers with the potential violations and infringements that it will potentially lead to. I would say that this is a case of the insane running the asylum but I'm not sure that the word running is at all applicable. Why are we governed by such morons?




#327925 Nikon AF-S Nikkor 24mm f/1.4G ED Wide Angle Lens for underwater

Posted by Paul Kay on 15 March 2013 - 03:17 AM

You may struggle with it behind a minidome - I tried a small dome at first but now use  my 24/1.4 behind either a (Seacam) WidePort or Superdome.




#327753 Nikon AF-S Nikkor 24mm f/1.4G ED Wide Angle Lens for underwater

Posted by Paul Kay on 13 March 2013 - 03:03 AM

I use the Canon 24/1.4 - it gives a very bright viewfinder image but cannot be used at fast apertures due to being behind a dome port. As a 24mm lens with fast AF and a bright viewfinder it should be great though.

Am curious about the Yarell's blenny shot- do you get many sightings of these little guys?

Hi Damo

Yes, mostly in Scotland, but I have seen them in north Wales too (I think the largest caught by an angler was in north Wales). I don't think I've actually seen one in Ireland though but I haven't dived much north of Mayo.

#319368 Diopter for Canon 16-35; Schneider or Aquaphot?

Posted by Paul Kay on 29 October 2012 - 12:38 AM

B&W = Schneider and if they make an 82mm it should be available here in the UK as there is a B&W importer (you could try SpeedGraphic. FWIW I've tried using achromat diopters and none achromats and have found little difference in actual performance. 11" is pretty good as a close focus distance especially behind a large dome (its measured from the focal plane don't forget) and the reduced angle of view, increased aberrations and lack of infinity focus make me wonder if its worth bothering.....


#318196 Flying Octopuses - comments on the proliferation of these images

Posted by Paul Kay on 11 October 2012 - 07:42 AM

At what point does an animal reacting to our presence shade into unacceptable disturbance?

I have to say that I have worried about this for a few years, particularly when seeing the efforts that terrestrial wildlife potographers go to, to avoid disturbing their subjects. Our subjects almost always know that we are there...

Its a good question because you are quite right, our subjects genrally do know we are around (at least those able to do so). So is our unavoidable presence the limit of acceptability? Should we offer incentives to subject matter ('baiting' as used by our terrestrial counterparts), use remote cameras (I suspect some creatures can tell that electrical or even metallic systems are presnt too) or simply touch nothing and disturb as little as is possible? Of course our presence pales into absolute insignificance compared to the 'adjustments' carried out by commercial fisheries so perhaps we shouldn't be too pedantic?


#315084 Sigma 15mm lens correction in Lightroom 4

Posted by Paul Kay on 23 August 2012 - 12:33 AM

Adam

I'm not familiar with Lightroom (I use Photoshop) but what exactly is this lens correction trying to achieve - a rectilinear image from a fisheye shot? Domes create distortion (because they are just a simple spherical lens placed in front of the sophisticated camera lens) as well as the lens, so an above water correction may well not work with the lens when its used behind a dome underwater because of the additional distortions added by the dome. These distortions will almost certainly vary depending on the subject distance and consequent focus setting, and additional distortions and aberations will occus as you focus closer. [Even with flat ports the amount of correction of chroma needs varied adjustment for different focussed distances so I'm sure the same (but worse) applies to domes too.]


#252223 Testing lenses underwater.

Posted by Paul Kay on 02 June 2010 - 01:24 AM

A large test chart is not needed! Smaller test charts are quite adequate - placed centrally and on the diagonal in the corners and at intervals along the diagonal if needed. The aim is to see the drop in image quality into the corners, not the overall variance in the whole image area. If the lens is correctly centered and aligned the images from the diagonals should show similar results. Laminating an A4 print is fairly cheap - few laminates will stand up to submersion eventually as few use truly waterproof adhesives, but test charts can always be reprinted.

The real question we need to know the answer to from the scurilous hack, is whether the images with mushy corners are actually used by the magazine - if they are then lens testing might just be an academic exercise :) .
