About Me

My photo
Delta, British Columbia, Canada
I took very early retirement from teaching in '06 and did some traveling in Europe and the UK before settling down to do some private tutoring. As a voracious reader, I have many books waiting in line for me to read. Tell me I shouldn't read something, and I will. I'm a happy, optimistic person and I love to travel and through that believe that life can be a continuous learning experience. I'm looking forward to traveling more some day. I enjoy walking, cycling, water aerobics & and sports like tennis, volleyball, and fastpitch/baseball. I'm just getting into photography as a hobby and I'm enjoying learning all the bits and bobs of my digital camera. My family is everything to me and I'm delighted to be the mother of two girls and the Gramma of a boy and a girl. I may be a Gramma, but I'm at heart just a girl who wants to have fun.

I is for IMAGES

Immense thanks to Denise Nesbitt for creating this incredibly creative site! All contributors post such interesting, inspirational, and impressive photos and writings and those of us who visit are inspired by your informative and illustrious offerings.

There are 3 IMAGE formats relevant to digital photography. I will try to illuminate them for as clearly as possible.

JPEG stands for "Joint Photographic Expert Group" and has become the standard format for storing photographic images in digital cameras and for displaying them on internet web pages. They are smaller than TIFF formats and as a result they lose some image data. However, “JPEG files achieve a smaller file size by compressing the image in a way that retains detail which matters most, while discarding details deemed to be less visually impactful.” (from http://www.cambridgeincolour.com/tutorials/imagetypes.htm)


TIFF stands for "Tagged Image File Format" and is used mostly in the printing and publishing industry. They are significantly larger than JPEG images and can be compressed or uncompressed making sure the image retains all of the image information. This type of file is excellent for intermediate files that you may want to edit later. Many digital cameras have the capability of saving images in either TIFF or in JPEG, but TIFF images take up excessive space. Therefore, it is recommended that one use RAW format because they are significantly smaller while still retaining more information about your image.

The RAW file format is digital photography’s equal to the negative in film photography. It contains untouched, "raw" pixel information from the digital camera’s sensor, containing one red, green, or blue value at each pixel spot. Digital cameras normally "develop" this RAW file by converting it into a full color JPEG or TIFF file, and then store this file in the memory card. Because digital cameras have to make many decisions when developing a RAW file, this format offers more control over how the final JPEG or TIFF image is produced. If you’re interested in the steps a RAW file takes to change an image into a TIFF or JPEG file, see
http://www.cambridgeincolour.com/tutorials/RAW-file-format.htm.

In conclusion, I thought I’d show you some of my favourite images from over the past little while, all using a JPEG file format. These photos gave me hope that Spring cannot be far away. Come with me for a little tour of my neighbourhood, culminating in an awesome shot of a reflection of the iconic Vancouver Hotel in a new skyscraper in downtown Vancouver. I'll be using that same photo next week for another reason, so keep it in mind. Be sure to turn up your sound to hear the accompanying music.

Are you taking a photography class? I'm signed up for one in April.....but it's only 3 nights and I'm sure you aren't learning all this in a short time! Yikes!

I did take one last fall, Nancy, and am waiting for the next one to start. I'm just studying through books, online, and Lorne is helping me. He's an incredible photographer!

Nice crisp images with brilliant colours. I use JPEG images for my blog. They also do fine for images in Wayne's books. - Margy

Fan.Ta.Stic! I love what you did with the slide show. I tried to pick a favorite photo but each one is as good as the next. And great job explaining jpegs, tiffs and raw shots.

Thanks for all the information. If only I could remember it all.

I really enjoyed your take on "I". Great information, stuff I really need to know more about. My first time with ABC Wednesday, think it will be really fun.

Although I have used the term jpg (jpeg) myself more times than I can count, I didn’t know until now what it really stood for. Interesting post and nice to have an option to go a little beyond the simple camera click. :)

EG CameraGirl said...

Nice reflection photos in your slideshow. The photo of the ducks on the fence made me laugh!

Jane and Chris said...

Your pic show will guarantee Spring soon, wont it?

Paula Scott said...

I'm wondering if you are teaching a photography class-you already have the curriculum unfolding here each week on ABC Weds! Great job! I have innumerable images. Call me an image hoarder if you will. I stand guilty.

Kay L. Davies said...

Fabulous set of photos, Leslie. I'm sure I recognized some of the locations (the dikes? the fen?) and of course the Hotel Vancouver, definitely, as you said, iconic.

Hmm. Always wondered what those meant.

Hazel said...

Glad to be reminded of what JPEG stands for in this post. Always see it around but quickly forget, just like 'http.' I love reading what you share about photography. I'm picking little bits here and there.
