16. When using an external flash or shooting against the sun, there are a few techniques
that should be followed in order to avoid a lens flare, which is often encountered when
using dome ports of any kind due to the reflection of the sun or strobe:
a. Images in which the sun is captured can be usually taken during mornings or
afternoons, when the sun is not as strong as during the middle of the day. In general,
the sun will have a much softer and successful effect during early and late hours of
the day and will also cause less of a flare.
b. Make sure that the strobe is not positioned towards the lens. When shooting a
nearby subject, for instance, it is better to position the strobe a little bit in front of
the camera housing rather than behind it (so the light doesn't reflect on the Wide
Angle Lens), or if you choose to position the strobe behind the camera housing,
make sure it's not pointed directly towards the lens, but a little bit tilted towards the
side.
17. After the dive, detach the wide angle lens and all components from the housing lens
port and rinse them in fresh water.
18. Dry and store in a safe protected place.
CARE & MAINTENANCE
1.
Please use the utmost care and do not use excessive force when assembling and
disassembling the different accessories, in order not cause any damage to the product.
2.
Keep the lens away from extreme high temperatures, as under direct sunlight, since it
might damage lens.
3.
Do not clean the lens with any chemical solvents or other materials, which might cause
damage to the lens.
4.
Never look at the sun through the lens.
5.
After Dive Care:
a.
Detach the lens from the housing lens port and rinse all lens components in fresh
water.
b.
To ensure that the accumulated salt has completely dissolved, it is recommended to
soak the lens in warm fresh water once in a while.
c.
Wipe the water drops with a soft cloth. Do not leave any droplets to dry on lens
surface, as permanent water spots may remain.
d.
When storing the lens and during transportation, make sure that it is properly
protected in order to prevent scratches, cracks or any other damage to the lens.
e.
Store the lens in a dry and protected area. Storing the lens in a low humidity
environment will decrease the chances of the lens fogging up when submerged in
water.
f.
Do not store the lens in presence of chemicals, solvents or fuels.
