I would also suggest purchasing the Marine Life Keyword list to aid you in adding ID keywords to your images:




It hugely simplifies my workflow....



In Topic: Remote Strobe Trigger

The limitations on using any "on board" slave sensor is that it will typically have to be in line of sight with the triggering strobe.


This means that you will (a) see the strobe in the image and (b) you will get the harsh light that is output close to the strobe itself.


By using a remote sensor on a cable, it allows the strobe to be placed "out of shot" and the light to be directed/shielded in order to use the softer light that is further away from the strobe itself.


I used the Triggerfish with the YS-D1 and it was fine.


All the best



In Topic: To Filter or Not To Filter

Hi Stuart,


Detailed instruction on how to make your first post are here!




In terms of your query, filters correct the color shift towards blue or green that occur underwater.


Post-capture white balance creates a global color shift. The most common result is that this drains away the blues or greens (as the software shifts the spectrum toward the red end). This leaves them looking very washed out.


Shooting in RAW captures all the sensor information, but given that there is little information in the red end of the spectrum at depth, it cannot capture information that simply isn't there.


By reducing the amount of blue/green light that the RAW image is capturing by using a filter, this allows the camera to white balance in a way that is more natural looking and retains the deep blue and green colors of the water column.


Most images have some sort of post capture work done on them. The point is that shooting with a filter on some types of image will give you better results post capture.


In terms of whether you chose to believe the information presented in the shared link, that is up to you. I guess the many underwater photographers that successfully use filters to enhance their images regularly will continue to do so, and if you don't want to use them that is up to you.


BTW, if you put "filter" into the search button above, or Google "Wetpixel filter" or similar, you will end up with over 100 results, some of which would give you more understanding about filters...just saying  :mocking:

If on manual, magnets need to be in. This cancels the pre-flash. Adam
