well, the popup flash on my new D300 does not clear the sigma 10-20mm lens on it...i do have an old SB-15 speedlight (non-TTL) so i had to figure out how to use it...

Are you using high-speed sync when shooting 1/250 ? Typically, the flash output is lower in high-speed sync mode, to allow for a faster recycle rate, so that may be the cause of the underexposure.

I'm not familiar with the SB-15 ... does that have a zoom head on it ? There appears to be vignetting on that last shot.

ok...tonite we are playing with control points in nikon's capture nx...tried to "fix" the overexposed shell of this turtle...hmmmm...may have to resort to reading the instructions

I bought the Sea&Sea TTL convertor and it flooded on the first dive (external to the housing) the replacement has arrived and I look forward to seeing how it works in March. I have twin YS110s.

the housing was just delivered...need to charge up a DS-125 battery and test TTL (plus or minus) with the housing controls

By bob...packing now! (Extraordinary BonaireTalker - Post #2460) on Saturday, January 19, 2008 - 4:49 am: |
did another capture nx control point exercise on a queen angel, used a black, a neutral, and a color control point...when using a neutral point one has to be able to locate an appropriate point in the original photo - if one really does not exist then you need to use the color control point to affect the color change...
|
By bob...packing now! (Extraordinary BonaireTalker - Post #2461) on Saturday, January 19, 2008 - 6:08 am: |
back to flash level compensation...capture nx reports BOTH from the camera setting AND the housing setting, indicating the total flash compensation and if manual flash is selected on the housing then reports the level of manual flash...

The one next to last is sharp as a tack! What strobe combo are you using? I't thinking of trying to add an existing DS50 as fill flash for my DS125. Your thoughts on that?

and back to the "system"...upgraded to a 266MHz CF card, new larger,higher speed hardrive in the laptop (with a "clean" OS)...no problem crunching the 25Mb + files off the D300

By bob...no april showers) (Supreme BonaireTalker - Post #2515) on Monday, February 11, 2008 - 8:17 pm: |
the flash level and wide angle bit...again...as i read it now the problem is the ambient light in the wide angle frame can cause an OVER exposure when using TTL flash control...looking back at some photos shot in program mode with F4.0-f5.6 i can see this was often the case - especially in shallow clear water - like at La Dania's Leap, Rappel, etc...

ok...another test pic...d300/20mm nikkor - 8"dome, ds125 and ds50 strobes...F11 and 1/60...way more than enough flash...turning the camera rig 90 degrees resulted in extreme overexposures so its looking like strobe placement does play a big role in determining effective flash level...shoot from the sides not over/under subject...
|
By bob...no april showers) (Supreme BonaireTalker - Post #2522) on Wednesday, February 13, 2008 - 8:32 pm: |
one way to avoid the problems of TTL and wide angle flash would be to shoot at night (or at least sunset)...note that the camera "single servo focus mode - S" which is in general recommended, presents a focus lock and unless you have a focus the shutter won't operate...an aiming light might help but better at this point to change the focus mode to continuous servo "C"...

backup strobe came...so i can now remotely fire two DS125 strobes without connecting the housing and tray...bob's hacked creative lighting system;)

had to test again as one strobe was not set properly...

still not quite set...

nope...talked myself out of the fisheye (for like the third time in the last couple of years)...hesitant now mostly because of whatever unknown problems shooting a fisheye underwater in a dome port with strobes may present...
|
By Bruce (Experienced BonaireTalker - Post #319) on Wednesday, February 27, 2008 - 3:29 pm: |
Bob, Thanks for the research. Sounds like you'll have plenty of wide angle with your 10-20mm and the dome. Once you get some water around the dome, that thing will really open up.
|
By bob...no april showers) (Supreme BonaireTalker - Post #2563) on Wednesday, February 27, 2008 - 5:32 pm: |
well, if someone got anything out of all this...i got more confused than i was i think;)
|
By bob...no april showers) (Supreme BonaireTalker - Post #2566) on Thursday, February 28, 2008 - 5:45 pm: |
but i STILL have 30 some rolls of old film;)
|
By bob...no april showers) (Supreme BonaireTalker - Post #2569) on Friday, February 29, 2008 - 8:33 pm: |
film! OMG how soon we forget;)
|
By bob...no april showers) (Supreme BonaireTalker - Post #2573) on Sunday, March 2, 2008 - 4:45 pm: |
took some film in...not real happy with the results...old film? scanner hot getting hot enough? seems like i started getting results like this last time i shot film...guess i need a new roll of film and also to let them develop the negs...once anyway...
|
By bob...no april showers) (Supreme BonaireTalker - Post #2574) on Sunday, March 2, 2008 - 5:26 pm: |
another of the above...
|
By bob...no april showers) (Supreme BonaireTalker - Post #2575) on Sunday, March 2, 2008 - 6:21 pm: |
the film scans (at this point) can still be cleaned up a bit;)
|
By bob...no april showers) (Supreme BonaireTalker - Post #2576) on Monday, March 3, 2008 - 12:08 am: |
i checked another roll from june 2006 (used camera as a backup)...it was acting up back then...again don't know if it was the film or not?
|
By bob...no april showers) (Supreme BonaireTalker - Post #2579) on Monday, March 3, 2008 - 5:42 pm: |
film again...it occurred to me that i probably didn't know much about film in the first place, my Fuji 400 print film appeared "fine" to me...kinda sounds like there is better stuff available, slower speed slide film i guess...
|
By Bruce (Experienced BonaireTalker - Post #322) on Monday, March 3, 2008 - 6:23 pm: |
Bob, If you're getting old film developed at K-mart, those are the results! The silver oxidizes over time. Not intending to be critical but,. Yes you should shoot with a 64 or at max 100 ISO slide film! I've read somewhere that ISO 64 slide has a resolution equal to a 50 mp digital camera. Since you use your own color correction you could have that developed anywhere. Happy snapping!

not sure to what extent having the exposure comp set at -1.7 had...also not sure how long the camera had been set that way, i have never used exposure comp on that camera so it was inadvertent...
