In Topic: GoPro, ActionCam X7 or ?

Today, 12:55 PM

Hello Dp,


This is quite an old post but in case you are still curious.


X7 is actually ISAW Extreme.




I got both the X7 ( now dead, bad unit I guess ) and the ISAW A3 Extreme ( i got 2, in case 1 went bad again....LOL )

My advice is , get the GoPro HD3+ Black and set Protune + Camraw and be happy. Choose its Dive Housing 60 meter rated or its the older HD3 original housing actually under a new name. Yeah, get the LCD BacPac too.


The X7 or ISAW A3 Extreme has built in LCD screen and they are so dark, you go blind underwater with it, unless it is a night dive. You can't remove the LCD screen, it is there permanently.


The 1080 50p ( or 60p ) resolution on this camera is very bad. The 25/30p is good.

At 50p its like scaled up and not true 50p.

Its so called UW white balance the Aqua is useless for your kind of dive.


I have not dove the X7/ISAW beyond 10 meters, was only doing shallow test dives and retire it after I seen the LCD screen is so dark and I can't see anything. Not having an equivalent CamRaw like the GoPro is another turn off for UW use, its hard to color correct it later in post.


Its exposure is jumpy too,  not so smooth. Kind of small flicker at times.


Wifi smartphone or tablet Apps , the GoPro is light years ahead.


Hope that helps.


I have the Sony Action Cam AS100 too, if you considering it.

Again for UW use, stick with the GoPro HD3+ Black and be happy.


Happy shopping....

I have the Nauticam NA-GH4 right here in front of me 


Hi Peter,


May I trouble you a bit please.


Is the assc port at the door a M14 size ? The front left at main body surely is an M16 for HDMI.

The Nauticam user manual stated the assc port at the door is M14 but Backscatter and Reef Photo reccomended the vacuum valve of M16 size.

I want to use the vacuum valve at the door assc port and keep the M16 one at main body for HDMI.

I fear the NA-GH4 user manual has a print mistake on the M14 assc port size at the door.


Page 9, item 20



The exterior look for the port plug is always the same between M14 and M16, so me kind of worried.




Hope its not too troubling you.


Many Thanks


In Topic: Sony A7S for 4K - what a disappointment

I think its not totally about  "Half done right".

When an OEM has professional models above the consumer level, they need to protect those pro models. 

Pro model is where the $$ killing is made...I mean the buyers get stabbed here....ha ha ha.


Sony is loosing money as an electronic company, but their insurance business is making good money.




Black Magic is a good example of a company which it probably has nothing to protect, it only has so few cameras and they try to make

the best for these models......at a reasonable cost. But R&D need money. Small company like BlackMagic can not order sensors by the 500K quantity, so they will progress slowly but I hope they will do well.


Its quite the same like Nvidia graphic cards, the crippled some functions of their new high end gaming cards in order to protect the crazy expensive Quadro line which is used mainly by professional graphic station.


Recently FLIR did the same thing :


They sell low cost US$1K unit by locking its capability, while the engine-internal is the same as a unit costing US$6K ....ha ha ha.

Just firmware lock....holy cow.


Its all about busines, how to rip off more $$.

If your girlfriend or wive on day request you to get her a Hermes as below :



You will know that no leather will cost that much.....he he he....its the perceived image you paid for.


Dive safe.........









In Topic: Hero3 Black. How do I take advantage of this high definition camera?

21 February 2014 - 09:52 PM




URPRO-SRP has filter for greenwater.



You can buy naked frame SRP filter adapter, to use that 55mm glass GR filter.



Do becareful when buying filter adapter for Hero 3 camera.

Hero3+ is a slim waterproof housing. It is 40 meter rated. It does not have LCD bacPac rear door, perhaps due to water proofing integrity, so you can not use LCD bacpac on this housing. GoPro do not make one. Planned to make one but it did not come to market.


When one buy the LCD BacPac today from GoPro, it is called Limited Edition. It comes with free HD3 Original 60 meter rated housing and all the bac pac doors. 

This means the filter adapter one need to use will be Hero 3 original housing one, and not the Hero3+ slim one.


The poly material of HD3+ Slim 40 meter housing is thinner than the Hero 3 Original 60 meter housing.

This Hero 3 Original housing is now named BacPac Compatible housing or some perhaps call it Hero 3 Dive Housing.



Hero 3 Original WB if using Auto, has more greenish/yellow tint than Hero 3+. That is the main difference.


Other difference :

In good light, Hero 3+ NARROW mode of 1080p is less noise than Hero 3 Original


Are you using AWB for above GoPro video or CamRaw ?







Helmstation is at 68 meter while bottom is 73 meter.


If you have time take a look to this tutorial. He tries to achieve the same Michael Bay look with different methods. Just check it from 19' onwards. Look how he change the yellow taxi color...



I never calibrated my Dell U2412M but I guess it was a lot cheaper than yours.




Yikes 68 meter....that I do not venture to.....he he he.

Thanks for the link David.
