How to achive this effect?
« on: 29 Jun 10, 23:07 »

  • I've been wondering about this shot from the photo contest. I love to learn how to shoot like this.
    I think neither strobe or flash was fired, because the subject is quite far for them to be effective. However if using natural light, how did the color come out so vivid. The image of the turtle is almost 3D.

    How can you achieve such a shot with just natural light? ???
    Please share some tips with me ;)

  • A good lens and SLR?

    Melvin shot this with a Canon 40D if i'm not wrong. At this shallow depth, natural light is enough. Once composition and camera settings are right, all you really need is to white balance the shot, tune the colours in photoshop and some other adjustments in photoshop.

    I think?? Maybe Melvin will share. ;)

  • Thanks for that. Lets see what Melvin has to say. Is there a possiblities that Melvin uses magic filter?

  • hey Din - I'm guessing there is no one trick - using a good lens, having the correct exposure, setting the correct color temp in the RAW editor and shooting in clear shallow water all help achieve a nice photo. He was most likely fairly close to the subject also. hope this helps!

    btw, subjects tend to "pop out" more when taken with a dSLR due to their shallower depth of field relative to a compact camera at the same F-stop.

  • Ok.. I'm a newbie at this.. but I'll attempt to make a guess.  :P

    Looks like he is using a very wide lens.  Turtle is actually very close.  So after he takes the shot, he white balance based on the turtle.  Background have a blue tint to it coz seabed is deeper then the turtle, it would have very little red spectrum reaching it and also further away from the lens thus more water volume in between so have different white balance setting.  I believe the pop out effect of the turtle is not caused by DOF but created by the general blue tint on the background.  Some photoshop work may have been done too.

    Melvin.. say something..  ;D
    So they call it a 'FACT' coz someone made some statements on a 'FACT SHEET'? hummm...

  • I believe it's shallow water, wide lens, white balance and curves adjustment in photoshop should do the trick.

  • I think as mentioned the key thing is to shoot in RAW and then adjust for colour temperature later.  This is much better than using a filter which essentially just removes light.  May look better straight out of the camera but using RAW and fixing later will always get better end results.

  • actually i think its the other way around - filters make it easier to get natural looking colours. with a filter, you are balancing the colours that are captured by the sensor. when shooting without a filter, the red channel has much lesser info compared to the blue and green channels.

    in my experience, the best way is to shoot RAW files using a filter, then post process to get natural colours.

    however, like you rightly pointed out, filters cut out light so you could lose at least 1/3 stop or more of light. and you will only be able to shoot ambient light, which means vis has to be good and keeping dives shallow. quite a lot of considerations when shooting with filters.

    the cons of using a filter with a dslr set-up is that you can only rely on ambient light for the whole dive and cannot use strobes. otherwise the colours would come out looking really funky.

  • I guess we are agreeing and disagreeing at the same tmie.....

    RAW is the way to go and you retain the most info.

    Filters make it look better without faffing about later but (IMHO) if you want to faff you have less to play with.  Obviously also the light absorption varies with depth so what works as a filter at 10m probably is less good at 40m.

    To be fair I am not a scuba photography fan, I have an old Sony and do use a filter but it has been on <10% of dives, I prefer just chilling out and looking around, photographers also tend to make the worst buddies....  I am pretty keen above water though but anyway.
