A waterfall up CR way from memory.

[The Vulcan]

It's nice composition but I'd have moved around a little to the left to lose the emptiness in the lower right corner.

Being critical, it's not sharp and the highlights are horribly over exposed. This spoils it for me. Digital is more than capable of "revealing" shadow detail and the general rule of thumb is "expose for the highlights - the shadows will be there". Maybe a slower shutter speed also to give a milky flow to the water.

Yes, motion blur. Exif data shows the shutter speed of 0.4 seconds and there's no way on earth you could freeze the image hand holding the camera at that shutter speed even if it was equipped with image stabilizer. Also as Vulcan has rightly pointed out no point overexposing it at the expense of using slow shutter speed blurring the image. You probably intentionally selected slow shutter speed to get the "milky flow" of the waterfall but then you should have used a tripod. Exif data doesn't show the ISO but the aperture of F7.1. Given the available light and the lowest ISO of the camera and the shutter speed the OP has selected, that could have been the maximum (or minimum?) aperture that could be selected as most point and shoot comes with F stop only up to F8, which might explain why the picture was overexposed.

How did you get all that info from my pic ??

Yes it was hand held from memory or I may have placed it on a log or something, I do not have a tripod.

I was trying to get that effect of the water flowing over and over, so if I had used a tripod and maybe a time dealy to take the pic to avoid moving the camera when you push the button, how would that stop the over exposure ?? surely it would be the same, just a sharper over exposure

Also as I know jack about photography, but love taking pics and wish I had learnt more when younger and with these new digital cameras, I tend to try many different settings not knowing exactly what they will look like and hoping for the best and then end up not remembering what settings the good pic came out on.

Having kids also, most of my photos are of them.

This information gets saved when you take a picture and some graphics programs can read it. I use PaintShop Pro version 8 and can see the following information:

Thats amazing, I know the camera or the original pic has some info tacked onto it on my files, but nothing like this.

Guess I need to visit Fortune and get some software.

First of all what was the ISO setting when you made the shot (I hope it wasn't set at Auto)?

And did you shoot it in AE (auto exposure) mode or manual exposure mode?

If I were you I'd just set the ISO at the lowest possible value (ISO 100 or lower, if available) and shoot at aperture priority AE with F stop set at F8 (minimum aperture on most compact digicam). That would automatically set the slowest possible shutter speed under available light condition to get the exposure correct. If possible I'd further push the exposure compensation value down to -1/3EV which should give the photo a slightly underexposed effect, but at the expense of faster shutter speed (so less "milky flow" effect).

Since most point and shoot cameras allow maximum shutter speed only up to 1/1000 or 1/1500 sec and aperture only up to F8, there's not much else you can do if the subject is so bright that the lowest ISO, highest shutter speed and minimum aperture of the camera can't capture the image in optimal exposure, perhaps other than using an ND filter, if your camera has a thread for screw-in filter on its lens top. It's like putting a tinted film over your lens.

No need to buy any sw here.

A standard image viewer like FastStone will reveal the info.

Just right click on the image and select Image properties.

You can download the programme on the web.

I just realized something. If you upload your photo to your gallery on ThaiVisa you can click on “View image property details” next to the picture and see the full details. Try it!
