highlights and Dslr

are you happy with the highlights of your Dslr ?

i 've an S2 and it seems to be really under the performance of a classic SLR, especially for the pictures taken in the blue with the sun inside of it (like shooting my wife looking at some coral reef ), even in Raw file ..........

any comments are welcome

:twisted: ....no comment.....

Wait for the S3....... :?

PS: tu me revendras ton S2 !!! (private joke)

t es la aussi toi ??

Dam you two, us dumb americans only speak english so you should too.

PS: If you couldnt tell I am just jokeing

Schade, acroporas, daß du uns Europäer nicht verstehst!

Don't mind I will stop picking on you ;-)

No problem with the sun in my shot...Canon EOS 10D, 15mm FE, Subal C10 Housing, Dual S&S YS120 in Manual, F22, ISO 100, 1/200th

Stu

Sweet!

Good example Stu! But I think that is atypical of what we usually see. Craig, yourself, and a few others have posted good shots with the sun in the frame, but more often, the sun just appears as a mono-color blue blob.

Jerome,

While it is NOT as easy to capture high-contrast scenes with a digital SLR camera, it is possible. You'll see that Stuart captured that shot at f22 @ 1/200 - literally the exposure limit of his camera. He could not shoot any faster or let any less light through the aperture. Also, he was shooting at ISO100.

This requires powerful strobes and careful attention to technique. But you can get good shots like this with a little practice. Conditions in the water are also extremely important. Jerome - I was not surprised that your shot was "cloudy" and that there appeared to be lighted fringes around high-contrasts objects in the scene. That isn't the camera's fault though - that was due to poor visibility in the Northern Med.

Sincerely,

James Wiseman

:shock: :shock: scubastu i ve no word to tell you my emotions ........

I feel a bit more rassured , i ll have now to experiment your great advices ......

James , there's still a problem with the S2 : the synchro flash speed is only at 1/125

Jerome, yes the syncro flash speed on the S2 is only 1/125th. According to Fuji, you can get 1/180th by hooking up to the PC sync port. I don't know how to do that as I have never tried, but I know there is a cable for it.

Here's the cable I'm talking about:

If you have a manual bulkhead on your housing, you might try setting your camera to 1/180th and see if the flash will sync. Take a couple of sample shots and look for a dark bar caused by the shutter. If there's no dark bar then you are good to go. Now that I think about it, I'm going to try this too.

The Canon 10D will sync at 1/200th which is almost a stop faster than the Fuji.

Cheers

James

The Canon 10D will sync at 1/200th which is almost a stop faster than the Fuji.

Tests by maxwell showed that the Digital Rebel can sync to 1/320. See http://wetpixel.com/PNphpBB2-viewtopic-t-4548.phtml .

The 10D will probably do the same.

I ll try this this week end in a local lake with the 10.5 mm and my 2 SB 104 , pictures available next monday 8)

I have managed some pleasing sunbursts with the D100 and then in what appear to me to be identical conditions, suddenly the big white/cyan blob appears! I have yet to see a digital that gets it right all the time.

Has anyone managed to get consistent good results?

I must say that given the unreliability of getting good sunbursts on digital, and the ease with which they can be achieved on film I tend to still use film for these shots. This afternoon I've been shooting divers on scooters and was using my F100 + 16mm for sunburst shots and my D100 + 10.5mm for side on and blue backgrounds. Pain taking two cameras, but I still think it is necessary for these types of shots.

I guess digital clipping will always be an item to care for, with any digital camera.

It reminds me of the same problem when changing from audio cassette recorders to digital audio recording: never go beyond 0 db, it sounds ugly.

in the analogue world clipping is smooth.

Therefore the histogram feedback is your peak meter for these kinds of shots / problems.

But digital cameras only have a contrast range of about 6 f stops (like slides, but they have smooth transitions). Even if you do minus exposure compensation it is often impossible to get the big contrast in the sensors range.

Especially if you were used to shot negative film it’s a big difference. Negative film is capable of capturing about 12 f-stops.

If you shot with minus compensation to keep the highlight clipping down, RAW is a good way to restore the shadow details as it uses the full 12 bit (4096 steps) of the sensor. But if a highlight area clips, RAW can’t correct it. A value complete white will maintain white.

:-) Die Leute aus dem „alten Europa“ werden nicht immer verstanden :-)

only above water example (no housing for digi )

this was the "best" I could get with - 5/3 compensation. not as good as slide would have done.

Appearently the D70 can sync much faster than 1/500 if you block off the two rear contacts on the hotshoe. I haven't tried this myself but some pictures posted on dpreview d70 forum at 1/3200 look great:

http://forums.dpreview.com/forums/read.asp...message=8243461

I think this is because of the D70s electronic shutter at high sync speeds. I imagine this does not utalize all of the iTTL functions, but these pictures using the SB-800 look remarkable anyway. I imagine that the effect on iTTL is moot underwater since most housings/strobes can't use it anyway.

Maybe this is the solution

Dam you two, us dumb americans only speak english so you should too.

Many would argue that Americans cannot, in fact, speak English.

That is true but then what else would you call it? American? I dont think we deserve our own lanugage.

Hey Tony,

Thanks! When you got it.... =)

So, when we doing dimsum?
