Term 3 Session 7 Importing using Picasa

(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)

To get the most out of using Picasa you can sign up for Google ... simply go to
and you can create an account .. try signing up with a user name made up by combining:

" your name" + "of" + "your suburb" (eg. bellfamilyofbelmont) it's easy to remember and
easy to explain to people .. that's where ""
comes from.

Once you have your account It's not too much trouble to use Picasa to upload to the internet.

Remember you really only want to put up pictures that you don't mind
others looking at because the internet is, after all, a public place.

That said Google does allow you to set levels of permissions on the photo's


"Album Properties: Edit

You can change the title, date, description, place taken, and privacy settings of your Picasa
Web Albums account at any time. Just follow these steps:
  1. Log in to Picasa Web Albums at using your Google Account username and password.
  2. Select the album you'd like to edit.
  3. Click Edit in the top navigation bar and choose 'Album properties.'
  4. Update your album.
  5. Click Save Changes when you're finished."
and also at

"Emailing Invitations: Sharing albums and photos

To share your Picasa Web Albums with friends, you can send them invitations to view your albums. On any page in your Web Albums, click the Share button at the top of the page. Then, you can send an email message with a link to that selected gallery, album, or photo. The email message will be sent from your Google Account for Gmail.
If you're sharing a photo from an unlisted album, your recipient will be able to see your entire album, but they will not be able to view other unlisted albums.
If you'd like a copy of the email to be sent to your email account, select the checkbox labeled 'Send me a copy of this email.'"
What this means is that you can have a relatively private Album and then send people emails to view
it instead of "spamming" them with big pictures.

What is this EXIF stuff ?
Exchangeable image file format (Exif) is a specification for the image file format used by digital cameras. The specification uses the existing JPEG, TIFF Rev. 6.0, and RIFF WAV file formats, with the addition of specific metadata tags. It is not supported in JPEG 2000, PNG, or GIF.

Using Picasa .. if your not sure check out
there really is a lot of help on line

one example of Picasa help is ....

Importing Basics: About the Picasa Media Detector

The Picasa Media Detector alerts you that new photos are available for import when you connect your camera to your computer using USB, place a memory card in a card reader, or place a photo CD in your CD ROM device. The Media Detector appears as a small Picasa icon in the Windows System Tray (the area with small icons directly next to where Windows displays the Time), and it launches automatically when you start Windows. Windows XP has its own media detection process, so in most cases you will not need to run the Picasa Picture Manager in XP.

Happy Snapping .... next session ...
you will also need to get and install .Net click on this link to do that
Paint.NET is an open source, raster graphics editing program for Windows,
developed on the .NET Framework. Originally created as a Washington State University
student project, Paint.NET has evolved from a simple replacement for the Microsoft Paint
program, which is included with Windows, into a powerful editor with support for layers,
blending, transparency, and plugins. It is often used as a free alternative to Adobe Photoshop.
It is available under the MIT License [2].

Term 3 Session 5 Exposure Value, Rule of Thirds, Software, "Stop Motion" vs "Motion Blurred"

(UPDATE Aug 2012 - I have removed images that won't display correctly but will leave the text here as reference)
Exposure Value
In photography, exposure value (EV) denotes all combinations of camera shutter speed and relative aperture that give the same exposure.
Exposure Compensation is a feature of a camera that allows you to adjust the exposure measured by its light meter. Usually, the range of adjustment goes from +2 to -2 EV in 1/3 steps.
This means that you can adjust the exposure measured by the light meter by telling the camera to allow more light in (positive exposure compensation) or to allow less light in (negative exposure compensation).

Exposure Value examples ... For a full view click on each picture
3 Pictures .. Exposure Value +/- 0.0 ;  -1.0 ; +1.0
all taken at 1/125sec @ f8

This day was extremely overcast so the overexposed picture (dark one) still
does not have a lot of sky detail.

Rule of thirds

The rule of thirds is a compositional rule of thumb in photography and other visual arts such as painting and design.[1] The rule states that an image can be divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines. The four points formed by the intersections of these lines can be used to align features in the photograph. Proponents of this technique claim that aligning a photograph with these points creates more tension, energy and interest in the photo than simply centering the feature would.

This photograph of a sunset taken in the Thousand Islands region demonstrates the principles of the rule of thirds


Once again a cloudy overcast day .. but at least I was there!!!

1/80 @ f5.6 EV -1.67       1/8 @ f9.0 EV 0.0          1/2 @ f18 EV 0.0
Fast shutter speed, short exposure Slow shutter speed, long exposure
Fast shutter speed, short exposure         Slow shutter speed, long exposure
Fantastic shot!
Motion in a scene can be frozen or blurred depending on the shutter speed and other factors. Blur can be used creatively to evoke a feeling of motion as in this shot of a waterfall in Yosemite National Park.

This program works quite well and is completely free ...
... if you like the way it works you could ... if you wanted to ... pay for the full version ...
... most people I know have not bothered and I've not heard of any problems ...
... this is the antivirus I use myself.
