In Topic: Do I need the dive housing for GoPro Hero 4 Silver?

27 March 2015 - 10:54 AM

Agreed. I got the Silver 4 for my partner a while ago and she's done 50 dives in Bonaire - many down to 30m - in the standard housing. No problem at all.

 

The difference between the standard and the 60m housing may only be the tension on the springs. They need to be stiffer for greater depth.

I'm with Jack and Nortoda1. Having had the Vivid for about a year and done roughly 100 dives with it, I would not now want to live (or dive!) without it.

 

I have had one or two weird readings where it has been green maybe overnight or at least the last 20-35 mins and then started to flash green/red when underwater. Talk about a panic-inducing moment. But there has been no leaks.

 

I haven't been able to pin down the reason but suspected some sort of temperature change. This happened in Bonaire a couple of weeks ago.  

 

I must admit I'm slightly dubious too of the advice you got at Buddys......

Hi

 

Was saying you ordered a Hero 2 Silver a typo?

 

If you have ordered one in the GoPro 4 series - the GoPro 4 Silver - you do not need an underwater housing. Don't know though about the GoPro 2 - I think you do need a housing for that.

 

Get the 4 - and you get a monitor on the back that you can see u/w as well.


In Topic: Why U/W Photo Always with Black Background?

Hi

 

Yeah, can appreciate you might feel annoyed by the number of black background shots.

 

But, in its defence, black/single colour backgrounds are not really a product of real post-processing. The aim is to achieve that effect through use of shutter/aperture combinations as Tim explains. Post-proceessing should usually be only necessary for, say, getting rid of the odd distracting spot of e.g. suspended sediment.  The whole aim is to find the background which will create that neutral background space - as you can see in Tim's two (really nice) pics. I doubt Tim did a whole lot of post-processing to get the result: it was about choosing the right angle and background. The whip coral goby shot is the perfect example. There is nothing at all in the background and Tim could use a shutter/aperture combination to come up with the blue he chose. 

 

But, yes, it can make photos all a bit same-same. No doubt someone will come along with a new style before too long and we'll all move on.....  :lol2:

Hey!

 

 

Yeah, I'm certainly guilty of often wanting to create a cleaned black background to shoot against. 

 

The reason is that a single colour background (in this case black) provides a neutral space to highlight the main subject. If you pick the background and subject carefully (luckily?) enough, they can compliment or contrast each other in a way that increases the effectiveness of the image.  Anything which adds clutter or distraction is unhelpful - hence the clean-up.

 

Black, generally, is the simplest neutral space that can be created underwater. Other colours can be shades of blue - against the water column - and the orange/red of elephant ear corals.

 

Many photographers (me included) actually seek out the neutrality or simplicity of colour of the background before looking for subjects to shoot. So, wait for something interesting to swim or walk into the neutral space. Then clean up in post-shooting anything which intrudes.
