    Hi guys

    Need some help from the photo pro's here...;)

    As you know I am running a NPS system, and thus my majority of light is actinic. I really want to take photo's and post, but I just can not get it right.

    I have a FujiFilm Finepix S5800 (or something.) It is not a SLR camera though. I can adjust the appertures and all those stuff manually - but I do not undertstand it.

    The moment the camera focusses, the white balance peaks, and this looks as if the light just bounces off a mirror and everything becomes all white... I am taking photo's without the flash, as the phot's would not have the nice deep water look with a flash (and flash is just cruel to ls...)

    What should / can I do?

    Hey Jaco, I use the same camera as you (I think). I also found it difficult taking out shots with Actinics. I just set mines to "Auto", flash off, and "Macro". Then just snap :p

    I also do that, but still, I get PLENTY of white flash from the light, and the water looks milky as well... This really makes it difficult, as I do not have any aditional lighting.

    I even tried setting the camera on super macro, macro, nominal light, night shot, fireworks settings the worx!!! Really a bit frustrating...:p

    I get nice full tank shots, but the moment I want to photgraph my polyps etc...WHAM!!!!

    Looks good (especially your "purple" regal tang...:razz:)

    But what about close ups on those corals? Are you getting any nice looking shots, or does your white balance also go haywire?

    Jaco, do you have a tripod?
    If so try using long exposures (3 or 4 seconds depending on how much actinic light you have.) without using flash or if your camera can do it set the flash intensity lower, fire the flash and expose for 3 seconds.

    I am not sure your camera will be capable of doing it, play around in full manual mode.

    Aperture basically is how much light goes to the camera sensor, the higher the number the smaller the aperture.
    Aperture also determines depth of field or how much of the "background" is in focus. Small Aperture good depth of field, large aperture less depth of field.

    I hope this is not too technical:thumbup:

    Here is an example

    On this shot below I used flash, F14 and exposed for 3 seconds. I also set the onboard flash of my camera to about 50% power.

    I use a DSLR but you should be able to do something similar with your camera.

    Jaco, you wont be able to adjust your power on your flash.. invest in a tripod.

    Okey Gawiedj... I playd around with some settings last night but did not get it right. I even brought the camera to work today with the booklet, so you could maybe assist me.

    This is whatmy camera have manual settings for:

    *Photometry (Multi / Spot / Average)
    *White Balance settings (can be set to shoot in incandescent light, and other whiter balances too)
    *High Speed Shooting
    *Sharpness (Hard / Standard /Soft)
    *Flash Brightness (can set this up to +2/3 and down to -2/3)
    *Shutter Speed can be set from 4" up to 1000 (4sec. to 1/1000 sec in 1/3EV Incrememnts)
    *Apperture can be set from F3.5 to F13.6 (F3.5 to R6.8 in 1/3 EV increments and F6.8 to F13.6 in 2 EV increments)
    *Exposure compensation
    *Macro

    I do not really have any idea of what the above means, but judging from your top post these are the setting I would need to change? (marked them in bold for you)

    But now, what would you recon be the best setting to put my camera on having a look at the above?

    You asked my how much actinic light - well, basically only one 39W T5 Actinic and one 39W T5 PURE actinic.

    The water really is very blue, and I would imagane that Macro must be on, as the close ups are obviously around 30cm away.

    THe photos I managed to take last night of my zoa's; looks nothing like yours. I just get a zoa that is blue lit from the actinic, or brown from the flash... Not like yours where you can clearly see the colors.

    Thank you for your help so far...;)

    Hi Jaco, I have not been around that much in the last week.
    Sorry for the late reply

    Set the apperture to F10 (I would start there and see what happens)
    Set the flash don to 2/3 (Start with the lowest setting and then set it higher if necessary.)
    Shutter speed for these kind of pics is not an exact science and depends largely on the amount of light available in your tank. Start off on about 3 seconds and see what the pic looks like. If it's too dark make the exposure longer, if it's too l"white" make the exposure shorter.

    Post some shots and lets see.

    I'll go look through my archives for some examples from when I took the pic above.

    Found some earlier shots.
    Here I used the flash and exposed for only 1/6 of a second. (0.167 seconds)
    Apperture set to F10
    ISO 200

    [​IMG]

    This one I used ISO 800
    Exposure 0.05 seconds or 1/20 of a second
    Apperture F5.6

    [​IMG]

    I took me a lot of tries before I eventually figured out how to do it with my camera, I hope this helps you figure it out for yours.
