FREQUENTLY ASKED QUESTIONS [LEARNING]

Here are some of our most frequently asked questions related to learning.
 

 
WHAT CAMERA SHOULD I BUY?


There are four main things for you to consider - What do you want to use the camera for? Your ambition level? Size? Price? Check our detaild guides - DSLR - Mirrorless - Compact

This is a moving target as new improved products come out on the market all the time. But here we give you some simple hints. There are different categories of cameras. DSLR is a bigger system where you can change lenses and it is targeted for the most ambitious photographers and the video functions is today fantastic on this units as well. Dedicated real video cameras raise the bar even higher when it comes to filming. The Mirrorless cameras are similar to the DSLR system, high quality, but smaller in size and the ML camera have interchangable lenses. The compact cameras that is popular today are of much higher quality than ever and the performance is getting closer and closer to DSLR and Mirrorless cameras on the most fancy units. Some people like to use their phones underwater and we have housings for that as well. Then there is the action camera category with Olympus Tracker and GoPro cameras in the front row. Action cameras appeal to users beacuse of small size, easy to mount on creative places and easy to use.

Video recommendations → If you to shoot videos but the equipment I find for video 4K unaffordable then check out - Sony A7S II models, Olympus EM5 MK II, Panasonic GH4 and GH5, Sony RX100 MK IV and maybe even the Olympus Tracker.

We are glad to help you choose and if you can answer the four questions - What do you want to use the camera for? Your ambition level? Size? Price? Then we will have good alternative for you presented very quickly.

 

 
 UW housing  
WHAT HOUSING IS BEST FOR MY CAMERA?   
 
This piece of equipment is going to keep your camera dry - so there is a couple do's and don'ts here. Unfortunately there are some underwater housings you do not want to get involved with. We are proud to represent products with a proven track record and a serious after sale services. In general lower cost cameras usually are put into plastic housings and high-end cameras tend to end up in housings made of aluminum. You need to look the quality, is the housing compatible with accessories, price and the supported in your area. Detailed information can be found in our Knowledge Base section. Three guides at the top for Compact, Mirrorless and DSLR systems. On this page there is of course much more useful info [Knowledge Base]
 

 
Macro lens Nikon
 
WHICH MACRO LENS SHOULD I CHOOSE FOR DSLR OR MICRO 4/3 CAMERA?
 
There is not a straight answer to the question. To choose it all depends on the subjects. If we count on "full frame equivalent" focal lenth a 60mm macro lens is easy to use and give you broad spectra of subjects but you have to eb super close to the smallest subjects. A 100-120 mm lens is good choise for very small subjects and allow you a more relaxed working distance. Longer focal length is a bit more tricky to shoot due to narrow depth of field and you can't shoot as big subjects as with the 60mm. In the perfect world you would buy both. Usually we recommend users to start with the 60 mm if you are not only into the smallest critters - then you could go straight for the 100+ mm option. Most seasoned UW photographers have two macro lenses in the bag, or more.

Check our lens guides for Nikon, Canon and Micro 4/3 all gatherned on the Knowledge Base page.

 

 
CAN I USE
AN EXTERNAL STROBE WITH MY UNDERWATER HOUSING?
 
The biggest step - quality wise - for your underwater images is when you start using an external strobe. And to many peoples surprise basically every compact housings and up can be equipped with one or two external strobes. It is easy. You just attach a tray and an arm so you can attach the strobe to the arm some distance away from the housing. The only requirement for using an external the strobe with fiber optic cable is that the camera's internal flash can see out through the housing. We even have a universal solution to attach the cable to the housing in front the internal strobe. We assure you that you will not regret to get a real UW strobe undereater.

UW photographerHOW CAN I IMPROVE MY UW PHOTOGRAPHY?     

There are plenty of information on the web but unfortunately a lot of it is misinformation. Thsi site is a good start to find out more at the Knowledge Base. Have a look around there. Exposure Underwater also do courses and "one on one" work shops with some of our talanted Ambassadors. We also do events mainly on the Swedish west coast where you meet others photographers for a weekend and develop together. You can also join our exclusive expeditons with Exposure Expeditions where you will join us at a world class diving destination and learn directly from the Pros.

    External_strobe 

I GET A LOF OF BACKSCATTER IN MY IMAGES? WHY?

If you are only using the internal strobe of the camera most of the problem is easy to fix by attaching an external strobe to your underwater housing. If you already have an external strobe and still get backscatter, white reflextions from particles in the water, then you have your strobe in the wrong posisiton, or the strobes are pointing to much directly at the subject, or you are missing a wide angle lens or you are simply firing to much light. Your strobes should always look over or on the side of the subject to prevent backscatter. We recommend all underwater photographers to learn more about underwater photography through a coarse or workshop. Look under Knowledge Base, events or expeditions to learn more.
 

O-ring_and_grease
HOW OFTEN SHOULD I
CLEAN MY O-RINGS ON THE HOUSING?  

This is something we found out that UW photographers do differently. Our experience is that the best method is that everytime that you open the housing you should take out the o-ring from the groove with a blunt o-ring remover. Clean the groove and the o-ring and put new silicone grease on the o-ring. Make sure you are sitting in a well lit area where it is easy to see debris that might be stuck on the o-ring or in the groove. People who are taking the time for this and do it on a regular almost never have any problems with leaking equipment. So we urge you to take care and change all your replacable o-rings yearly. It is a good investment.
 

   Cables    
OPTICAL FIBER CABLES OR THE OLD STYLE METAL CABLES?
 
The optical fiber cables and the classic "old school" copper cables do the same job. It is more people today using fiber cables. All new DSLR housings can accommodate both types and most compact housings operate with fiber optic cables. The fiber optic cables has the advantage that they are unfloodable, and you get TTL photography built into the system at no cost and the actual cables cost less. The disadvantage is that you are using the internal strobe to trigger the external strobes and therefore use up the cameras battery quicker and you are also dependent on the recycling time for the internal strobe. This is today solved by triggers and optical TTL converters. Using these then optical cables are also super fast. The analog, or copper, cables are more rugged and sturdy cables. They are great for fast action.
 

I LOVE MACRO BUT I DON'T SUCCEED WITH TINY SUBJECTS? IS IT POSSIBLE TO PHOTOGRAPH SMALL NUDIBRANCHS (10 MM LONG) WITH A MY EQUIPMENT?

Yes, of course. If you have a camera in a housing, compact, mirrorless or DSLR, many different 67 mm threaded wet macro lenses (sometimes called diopters) can mount to your housings front and you enjoy a much magnification depending on which wet macro lens you choose. Either you have a 67mm thread already or you need an adapter. Most used wet lenses are Nauticam, Sea&Sea, SubSee, Inon and Dyron. Contact us for best unit for your set up!
 

 
 Arm Mega float Inon
MY HOUSING IS TOO HEAVY UNDERWATER (NEGATIVE BOUYANCY) - HOW DO MAKE IT EASIER TO HANDLE UW?
 
This is a common problem for many users and it solved by using arms with more bouyancy or additional floats to your existing arms. There are different arms and the wider arm the more bouyancy. It is easy to balance the system as most floating arms have a stated bouyancy valvue in grams. If you put your complete camera rig underwater and weigh it with a sport fishing scale then you will see how much negative boyancy you are dragging around. Recommendation → The complete underwater rig should be slightly negative underwater but not to much. So it is a matter of getting the right arms or floats in the right ball park. Check out the Arm & trays section on our site as the bouyancy is stated on each arm. We are of course glad to help - contact us [here]

HOW CAN I BE SURE THE HOUSING IS WATERTIGHT WHEN I GET IT DELIVERED?

All undewater housings are individually pressure tested before they leave the producers. This is for sure. Recommendation → But still we recommend that all equipment is tested without camera and lens inside the housing the first dip as things can happen during transport that you are not in control of. Do a safe test dive in a pool or in the sea in pool-like conditions, and if not possible at least test in the bathtub.
