I always have trouble with this and no matter how many times Braddsn has told me the same thing I always forget. I took a series of pictures in my living room the other night and the only difference in them is the ISO settings and the flash on or off. I do not know if this will help anyone or not as most of you are better at this than I am but it does show the differences in settings.

The first two are automatic setting on my camera where it chooses, though i did force on and force off the flash. These are also held in my hands so there may be some blur because of that:
This one is auto ISO with no flash

Kinda looks like 200 with the flash on was the best choice. The only light available was my laptop sitting on my lap, a light behind me and the TV.

Yea, I kinda like that one the best too..But your leg is so blown out..... Im gonna save this for gretchen as she is much better.......Im still learning and having issues at night as well.....

Looksl like maybe you leg being in the way might have thrown things off a bit......??????

You could have at least posed your dog like huntrz did in his front room with his cat.........The doggie in the chair would have made the picture look much nicer..........lmao...

Mrs. Bird has her spot on the couch, I have my chair and Costello's chair is that yellow one. He is about the only one of us that sits there, his eating spot for his treats is eiter that chair or where Mrs. Bird normally sits.

YES! ROFL ..........you know what that little dog does kinda look like huntrz dog too....what kind is it????

Is that chair yellow or gold??? It's a couple different colors in your pictures up there......lol.... Mrs. Bird must handle the decor huh? lol... B usually don't say much but one day I tried to bring home some leppard print stuff for "our" bathroom and it got returned the next.... B wasn't feelin it....So then we went with the rustic theme instead.......lol.

I DO NOT DO DECOR!

And I DO NOT PAINT!

If I did there may be a shotgun hanging on the wall on two large spike nails!

The chair is kind of a yelloish gold, it was given to us and my wife likes it so it is there.

The dog is a Brussell's Griffon, or what I often call him is a S***HEAD. He is a cool little dog though and quite funny!

I'd use bigger nails, rust or rust free and probably woldn't drive them in all the way as they wold also double as hat hangers, or whatever else.

Okay - here we go with ISO Explained...(well I hope LOL)
You are probably familiar with ISO on film used in a film camera. It’s the ’speed’ of the film - higher ISO values mean you can take photos in lower light. As an example you would use ISO 100 in bright daylight and ISO 800 in a lower light situation...

Essentially it's the same in digital...


ISO indicates your digital camera’s sensitivity to light. The higher the number, the less light is needed to take a photo that is bright enough (correctly exposed).

In bright light (like the middle of a sunny day), you’ll normally use ISO 50 or ISO 100. These are the lowest settings and can be used because there is lots of light around.

However, in lower light, your camera needs some help. There are two ways of doing this:

Decrease Shutter Speed
With a slower shutter speed, the camera has more time to ‘take in’ the amount of light it needs. Unfortunately though, the slower the shutter speed, the more chance that your images will turn out blurry.

Increase ISO
Rather than decrease the shutter speed, you can increase the ISO. As I said above, this will increase the sensitivity of the camera which means you can get the same shot with less light entering the camera. Thus the shutter speed can be kept low enough to avoid blurry images.

As increasing the ISO will increase the shutter speed, a high ISO will also help when taking fast moving sports shots. You’ll get clear, crisp shots with no blur.

However, I still recommend you use the lowest ISO possible. Why?

Problems of using a high ISO
Using a higher ISO means the camera has less light to work with. Unfortunately this also means that ‘noise’ is introduced into your camera.

Your camera’s highest one or two ISO values may produce a lot of noise in your image, so I suggest avoiding them unless the light is so low that you have no other choice.

Auto ISO
Fortunately most of the time you don’t need to worry about selecting the correct ISO. Most cameras have an “Auto ISO” setting. With Auto ISO, the camera will look at the amount of light in the scene and change the ISO appropriately so that the shutter speed doesn’t get too slow.

ISO Values
If you choose to use a manual ISO, what values should you use?

ISO 50-100. Suitable for bright light (like outdoors on a sunny day.

ISO 200. Great for overcast or cloudy days. However on budget cameras some noise will be seen in your image.

ISO 400 and above. Use for indoor or night shots (even if you use a flash). Useful to freeze the action in sports shots. - also useful in the woods where although it's high noon..it still is lower available light...

BUT - each brand of digital camera handles it differently..some will only produce noise above 800 or 1600..but some it will start to creep in at 400 even...using a flash will help some with the noise - (those disgusting grainy looking pixels) so experiment with your camera to find the level of noise that bugs you up...
There are noise reduction softwares and most of the standards..i.e. PSP and PS have a noise reduction tool..however if you really start blasting away the noise, you'll also lose detail and sharpness..

Hope that helped! :)

Thanks for the lesson Mrs. Steele..........:D :D
