Right Vicki, I have promised to give you a few tips about understanding how all the information contained in the EXIF can be used to manipulate how the final image will look.
What you need to do is to find a still subject. Something that doesn't move too quickly. It should also be brightly lit, but preferably not by direct sunlight. A bunch of flowers near a big window will be perfect, but you can use anything you like. As you can see, I have opted for coins arranged on a newspaper.
Start by taking a picture in automatic mode. While you do this, take note of the settings the camera selects. In my case, it was an aperture of f10, a shutter speed of 1/100 and an ISO of 800.
The resulting image is below.

Now, for the second image, lengthen the shutter speed, meaning you select a smaller number. Here I selected 1/25.

Because the exposure time is longer, more light passes through the lens during the exposure and the resulting image is lighter.

For your second image, I would like you to select a larger aperture, that means a smaller number. I have selected f4.5:

Go and have a little practice, and next time, we will look at how the aperture can be used to creatively manipulate the image.

No flash.
No, no. Of course, don't use the settings I've selected, take a picture in auto first, and then set according to that.
tripod if you have one.
Ideally you would use a tripod though. If you don't have one, the slow shutter speed images may be a little blurry, but you will still be able to see the general principle.
Did this help?
Vicki,
Was just wondering how you got on with this? Was it clear, or did you find it confusing?
Hello...
Ed,
I've been on babysitting duty for my tenacious 15 month old grand daughter so I havent had time to do much with it yet. I have read it through and the directions seem easy enough. I will post out and let you know how it goes as soon as possible.

Bundles of Joy.
Poor you, you must be exhausted.
I've been told that the best thing about being a grand parent is the fact that you can hand the cute little bundle back when she become too tiring!
By the way, I am writing an article about studio portraiture and it will feature a section about photographing children.
About the tutorial, I was just looking for a bit of feedback with the piece. I was worried that you found it confusing.
It doesn't matter that you did not actually do the whole thing step by step. What matters is that you grasp the concept. To be honest, the idea is that, if you read the piece through, you should understand how it works.
That's not to say you shouldn't practice it when you get back to your camera, but rather that it will make the process a bit more intuitive.
The only reason why I asked how you found it is because I aim to adapt it a little and turn it into a feature. It will be a sort of 'step-by-step exercise' to be added on to the Basic Photography articles.
Talk soon.

Ed
Ed,
After trying to do this I see how amazing you really are. Your pictures look just perfect in what your trying to get across. I had a few minutes to try a few.....ugggg
Well, I didnt have a tripod so that didnt help but here are two. I will be practicing this some more in the near future.
Oh what a bundle of joy She is...
Yes, Grandma's job should be to have tons of fun, give her lots of goodies and then send her back home to Mommy. It has been a bit rough with my daughter and grand daughter (and 10 yr old son) living in our small humble home. I am tired much of the time.
But then I look at her face and its all ok...

Well done!
You flatter me.
You did really well on those.
The second image shows a little bit of camera shake due to the slow shutter speed, but it shows that you grasped the concept.
You may have noticed that for each click that you go "up" on your shutter speed, you have to go one "down" on your f-stop.
A tripod is a worthwhile acquisition. And not only for slow shutter speed shots, I use it for any subject that does not require me to move too often, like landscapes and still life, if for no other reason than that it makes me think a bit more about where I set up my camera.
In my humble opinion it is the object that will most improve your photography for the least amount of money.
That's not to say that you can't take great pictures without one, so I'll give you a quick rule of thumb: if you want to avoid camera shake, you need to select a shutter speed which is faster than the length of your lens. So for a lens with a focal length of 100mm you want to select a shutter speed of faster than 1/100th of a second.
Do that, and your images should be free from blur.
Grandparents
Aaah, really sweet. (And an excuse to practice some photography too.)
My favorite pictures of children are ones that make you smile and the second one certainly does that.
Your kids are really lucky to have a babysitter nearby. As I've said before, my parents are based in South Africa and my wife's are in France, so no such luck for us.
Ah, I think Im in luck!
I found a camcorder tripod that I've had up in the attic for years. Forgot i even had it. Im hoping it will work. I will post more as I can.
Thanks again Ed, Wish you and your wife were my next door neighbors though.¬¨¬®¬¨¬Æ¬¨¬®¬¨?Ü‚Äö?Ñ????ë?????´‚Äö?Ñ????ë‚Äö?тĆ :o)

A bit of support is better than none at all.
Perfect!
Camcorder tripods generally fit cameras (and obviously visa versa.) The screw is a standard size so it should be fine.
Like most things in photography, your tripod is chosen to suit your budget and there are models out there that could really break the bank, but provided you do not suddenly embark on a astro-photography expedition or buy a 4x5 inch large format film camera, your attic discovery should be fine.
photo album question
I didnt see a website question thread so I'll ask here.
In my photo album, on one of my pics, has the word "updated" over the top of the photo and when you click on it it has all the Photo Properties under it. Cant figure out how this happened....

Very good question
Vicki,
I can honestly say I have no idea how that happened.
I knew the function was available in the Gallery, but I have turned it off by default.
I am going to mess about a bit and will let you know as soon as I have figured it out.
have to share...
Ed,
So I was a bit bored late last night, everyone was asleep, so I decided to go out in the dark and mess with the camera. I started trying to take some pictues of my house with the porch light on. (Shows how bored I was hey?) First I started by trying to lengthen the shutter speed just to see if it would work with no luck. (Not enought light I dont think) Mainly all black. Next, I tried using a larger aperture and son of a gun it worked! I could auctually see all of the front of my house. I was so darn excited i was doing a dance in the middle of the street. Im sure I looked like a fool but i didnt care cause it worked!

If anything, Im learning this cameras is way more techinical then I realized. Just gives me more the learn.
What does ISO stand for?
Thanks Ed!

Eureka!
Vicki,
Sorry for the delayed reply, I was working on the studio portraiture article. (It should be posted on the site later today).
I absolutely love those Eureka moments. Makes life worthwhile, doesn't it.
That's part of the fun of photography, it is a constant journey of discovery.
I once saw one of my photography lecturers do a little dance like yours in the studio when he thought no one was watching. After I announced myself and we both brought our fits of giggles under control, he explained that he had just devised a new technique to be used in food photography. (Which he had been doing for over 20 years). Instead of using real cream in dishes, which melts under hot studio lights, he had covered his strawberries in shaving foam.
ISO is short for International Organization for Standardization, the body which created the standard. Personally, I would have opted for LSI, Light sensitivity index, but nobody asked me.
And it's true Vicki, there is a lot to learn, but you have just taken a big step, and with your enthusiasm, I'm sure you'll be a master in no time.
Moving on...
Does that mean you are ready for the next lesson?
Sure...
Sure, whats next?

Well, I thought we'd start with depth of field.
I'll do the images and copy over the coming weekend.
Delays and excuses
Sorry about the delay here, Vicki, I have been meaning to do it, but as you will recall, first I got ill, and had to stay in bed, then I got better and had to go to work! Both things leaving me unable to do the tutorial.
I will do it as soon as possible, though, so check back soon.
No rush Ed :o) A true
