Driving home i spot this great sky and rush home for my camera. I go home, somehow get the other half stuck with me, drive back to the spot. Park the car up where i could (country road) walk 20 mins over a field Whilst setting up my camera on the tripod and changing lens' at the same time so not to miss it), take some test shots, realise i don't have my remote control with me! Then realise i also left my SD card in the PC card reader! I use the mem card from my phone, i take the image without a remote as steady as i could, -2EV, 0EV, +2EV, we run all the way back to my car as it was not parked great.. Drive home.. Get inside, load up the images, see that they are pretty steady and aligned (Woop), then process in Photomatix.. and imagine my dissapointment when i get this...

What is it and how do i avoid it in future? :(
I did salvage th situation with some tone mapping in CS3, but it's just not the same...

my guess would be movement in the sky, when the sun is so low it moves down quite quick.

Looks like the camera couldn't handle the highlights of the sun. What did you meter for.

I don't know how to answer that question. :stupid:

I'd be interested in this also as I like taking pics of the sun but they tend to blur as if my cam can't handle it.. Is there a setting to change to help your camera capture the sunset/rise clearly? :stupid:

Should my ISO have been higher, i had it at 200? I let camera control the shutter speed and apature and i controlled WB, Exposure, ISO and Focus.

Basically -2 to +2 EV is not going to cover the dynamic range of this scene - the sun is probably over 10 EV brighter than the foreground. DR of typical dSLR is only about 7 EV (I think). You should have gone something like -7 to +2 to get the shot.

In what increments? My Camera only goes down to -5 i think, so i should have done -5, -3, -1, 0, +2?

I didn't notice what lens or mm you were using. I took this shot in Aruba a few weeks ago. Setting were ISO-100, F 5.6, 1/250 sec, focal length 200mm.
It looked to me that the second shot was right at the sun and the hot spot was right in the center. Try putting the sun off to the side a little.

What camera/lens do you have bud?

As a side note, I don't take multi shots for HDR, I'm lazy and can't be bothered carrying a tripod. Shoot RAW and process it to create as many +/-increments as you like. Don't over do it though as you will get noise in the shadows. You kind of need a camera with a decent DR to start with to get away with it though :)

Two stop incs should be fine. You can get whatever exp comp you like if you shoot manual :-)

Is the D40 not good enough for that?

Is there a filter to take it down another few EV?

is it wrong i like the original image? kinda funky can i have it? how did that happen was it a long shutter speed? is that how you get the cool cloud effect?

Anyone disagree with this statement? Use your spot meter option directly on the sun and then look at bracketing. This will use a much faster shutter speed as the subject is the sun. An additional filter will only slow down the shutter and produce the same results as the contrast has not changed.
Film can handle a much bigger contrast ratio than digital and I have shot this type of image using a 2 degree spot meter with a medium format film camera.
I have also achieved similar images using digital but the contrast was a bit flatter.

I do this for hdr too, saves you worrying about movement as well.
