D70 High shutter speed problem

[gooseberry]

Are you guys sure that this is not due to underexposure ?

1/4000 or faster shutter speed, ISO 200, max f3.5 on the kit lense.

It'd have to be a very bright scene to get the correct exposure for those settings. Shooting at a white wall would definitely be underexposed I think...

You can try to shoot the over cast sky. If not enough, try to include the sun . I mean, there are situations that you can shoot at 1/8000s. ie. given direct sun light, f2.8, ISO200; the calculated shutter speed should be around 1/6400s, right?

OK finally posting my test result of this issue.

This is a whilte wall, with some sandblasting paintwork, taken with 1/4000s shutter speed, f2.5. Ok looks a bit grey lah, but I think is is OK for this illustration. At 1/4000, it is absolutely OK. No problem.

This is where the devil rears it's ugly head. At 1/8000s and f1.8, the slight magenta cast on the right side can be seen if you look at it closely. For a more dramatic effect, just download this image, open it with photoshop and do a "auto colour" and you will be thrown off your chair.

Yes, the problem is there. Nikon, where is my solution?

yah look like same as mine ...

Well, luckily it doesn't show up in 1/4000. So at least not too bad. If you really need 1/8000, try to compose it more towards the left and also in conditions or background with no uniformity (eg cricket, the background perhaps can try to get a grp of audience nicely bokehed). At least better than nothing, sometimes it's better to be able to just get the shot, a good one. Afterall, if someone only says that my photo is exposed ok or WB is right and nothing else, i assume that he meant to say that the photo sucks. :bsmilie:

It's not the end of the world. 300D/10D/D100/ist D you want 1/8000 also dun have.

Well said. Actually I still don't know when I'll ever use 1/4000s shutter anyway.

Yes, if the only thing people say when they look at your picture is "Wah...very sharp ah? Nice colours too!" and nothing else, it means your composition or photo as whole has no other appeal. :embrass:

Actually what's worse is, you've got a great composition, a great expression, a great moment, but your metering or focusing screws up and you're left with a terrible image that you have to pray for a miracle to salvage. :cry:

Yah, the other Charlie company (C****) don't even have 1/8000s to deploy even if they need it. :bsmilie:

Agree it's seldom used. I had 1/10000s on my previous camera (f******* which can also sync the flash at 1/10ks for close range and 1/1k otherwise) but found that I seldom need to use faster than 1/1000s, even under bright daylight at ISO160/200. No point using a very fast shutter speed and end up with grossly underexposed pics (unles very high ISO was used).

Well, apparently D2H also has this problem. *LOL* If one techno masturbates enough, anything can come up. :bsmilie:

:dunno: :dunno: :dunno: Strange, never encounter such problem b4, have shot @ 1/3200 and 1/4000 at f/2.8 ISO200.

Lots of hoo-haa on dpreview, seriously i also don't know how the guys there measurebate. :dunno: Other than really white clouds, i still get it underexposure @ f2.8.

Another instance that I have techno measurbated before is using a flash with GN 120ft/ISO100 full power and flashed a moving fan blade @ 1/8000s, ISO 400 I think. Did not have access to any 'faster objects'...hehe. No problem with my D70 too, or maybe i have lousy eyes. ;p

How are you able to do that? I thought flash sync speed for D70 is 1/500s. :dunno:

Well, I also don't know as i am not exactly a techy person, i just like to take pictures. I just set it from manual flash to 1/16th power on my Vivitar 285 and it all flashes ok. Exposure setting is done via aperture change anyway.

Alright, i am sure everyone loves techno masturbation. Samples here. 1/8000, f3.5, ISO 200 (supposedly they say that ISO 200 will cause the colour shift, high ISOs will not.....so to satisfy everyone i shoot in ISO 200 lor... :bsmilie: ) Do inform me if i have done anything wrong. :sweat:

I think it's time to lighten up. Take more pics, i took nearly 1k in just 2.5 hrs on Friday afternoon at Suntec City. :bsmilie: Nearly 200 usable pics in the end, i spent Saturday and Sunday post-processing. Man, headache! :bigeyes:

Top 10 D70 problems.

10. Mirror slap causes minor earth tremors
9. There's green color in images of grasses and other plants
8. When you see funny colors in cross paterns, that's a' moire!
7. It can't be used when travelling to the sun (no 1/8000s at iso 200)
6. It doesn't let you have your cake and eat it too (RAW and JPEG Basic only)
5. You actually have to format memory cards? Rubbish!

4. Viewfinder is not large enough to store spare lenses, CF cards, and the car keys.

3. It is not made of military grade anti armor piercing Titanium-Chromium alloy with a Hafnium Carbide coating.

2. It has some kind of forcefield that does not allow you turn the camera vertically (however, it can be deactivated by a homemade chinese battery grip)

1. And the number one problem with the D70................


..............It causes you to spend countless hours in a forum dissecting every parameter, issue, ways to reproduce more problems, asking for serial numbers, yelling at Nikon, yelling at newbies and trolls, you haven't been to work in days, you forgot to feed the kids, Where's your wife? What wife? And to top that, it doesn't come with a miniature nikon employee -in the camera, to automatically process the image -in the camera, to your exact desire and specification.

What mode were you using? A, S, P, M?

 

[2100]

Manual, it's actually reported in the EXIF on pbase. Actually i just tried A, S and P, and dialed in exposure compensation accordingly, all ok results leh.

The reason I asked was because if you use A, P, S modes, the shutter will automatcally adjust down to a flash sync speed, ie, 1/500s or slower in the case of D70, when it detects that you have mounted a flash and it has been switched on. Just need to confirm that this has not happened.

there's no communication between the D70 and the Vivitar 285HV (it only has a centre pin) except for the centre trigger and the camera probably doesn't know a flash is mounted.

One thing to note though is that when the shutter speed is faster than the x-synch speed (1/500s), there may be uneven flash exposure. FP flash and its equivalent solved the problem by flashing in "pulses" and allows syncing of the flash (with even flash coverage) as fast as the camera's fastest shutter speed (e.g. in D2H and canon d/SLRs) but at a reduced range.

you could try with the SB600/800 turned to manual/auto mode

My number one problem with the D70 now is the credit card bill is due, and I don't know where to find the money to pay it! :cry:
