How to apply ISO?

[maple]

The Canadian fall colours are glorious and I enjoyed myself immensely over the long holiday weekend.

These pictures were taken with my new Canon 10D, under P mode without flash. They were taken at about 5pm under the warm orange sun. Evidently, the automatic exposure was too long for the speed we were flying at (on a helicopter). How best should I choose my ISO? Or should I have used the panoramic feature? I doubt that the flash would have been of any use?

Sample 1 was taken from inside a speeding vehicle. Notice that the trees on top are blurred.

Both Samples 2 and 3 were taken from the helicopter and they are both not sharp as well. I must admit that I am very much more used to my G2 - I haven't really read the D10 manual as I was rather impatient to just use it right away! I think I don't even know how to change the ISO settings! Any advice? Thanks!

i personally (others may/will be different) I usually use the lowest possible ISO for the exposure. I'm not saying i use 100 iso all the time, but what i'm saying is, i leave the ISO as the last setting i'm willing to adjust. If the the speed is too slow, and i've got the aperature as wide as it'll go (or as wide as i'd like it to be) only then will i go into changing the ISO.

Changing the ISO is very simple. There is a button at the top of the camera above the settings display screen, labled "drive-iso" Push this button then use the large dial on the back of the camera to choose your desired ISO. Hope this helps.

I was out in the hills near Montreal this past weekend the colors are wonderful.

You didn't say what ISO you had it set at but I would guess it was 100. This is really a matter of personal preference as to what shutter speed you feel comfortable hand holding (the tripod thing from a helicopter is a little dicey). I shot all of mine this weekend at 100 or 200 depending on the light. I try to make sure that I am up around 1/250 second for hand held shot using my 70-200 and 1/125 second for my 24-70.

I would seriously suggest that you read the manual and learn how to change the ISO. It is very easy and fast. I've read my manual from cover to cover several times and it is well worth the read.

Thanks Mike, that was a snap! Although I am left wondering why it wouldn't go down to ISO 50 as my G2 does. Also, the latter has fun stuff like B/W, Sepia, etc which the D10 doesn't. Seems like more fun packed into the G2!

I promise to read the manual cover to cover over the weekend!

I just checked, and the pictures were taken on P mode at ISO 100. I think they would have been sharper if I had taken them at ISO 400 (dim setting sun light plus helicopter speed and erratic movement).

By the way, I was at Mont Orford, my first time specifically there for la fete des couleurs. Quebec is amazing!

Maple,
The 10D has an ISO range of 100-3200. There is no 50.

the time to bump up your ISO settings is when you need to get a faster shutter speed.

The images you post certainly look as though a faster shutter would help but you did not tell us what the speed was.

Nor do we know the lens and thus the maximum aperture that you have available.

Quick and dirty rule of thumb,.. open aperture to get a required shutter speed... when you run out of aperture, boost ISO.

(of course the rules change all the time like when using a tripod on a stationary subject etc....)

It was the Canon 24-85mm IS.

I have little or no idea of aperture... guess it's time to read one of those Idiot's Guide To XYZ. Does one change aperture on the D10 just as one does the ISO?

[CyberDyneSystems]

Yep :D

Pretty much. It is an equation of a given aperture @ a given shutter speed @ a given ISO sensitivty that results in correct exposure.

These are the three ingredients that you have immedite control over in camera. There is ofcourse a 4th ingredient,. and that s available light! :D

Wlcome to the world of the SLR!

It is imposing at first! but it is the begfinning of a new word of flexibility and control over our images!

Start just by reading the 10D manual,. it tells you a lot about how the controls function,. not just where they are. :)

While you are reading the manual, please check for the panoramic feature that you mentioned.

Taking shots from the air is a bit of an art in itself but the prime consideration is the fact that you are experiencing quite a bit of vibration and good shutter speed is a basic requirement.

Not to mention you're shooting through window glass. Definitely not the ideal conditions.

Normals I use ISO 100 and its very good! if I need more, I apply "neatimage" after taking a picture with high ISO.

Maybe try AI-Focus! because you are in an moving helicopter the focus changes. try it!

.... and welcome to DSLR world! I had a G2 too and I'm not used to read manuals, but I started doing that when I got my 10D
