Making the World a Better Place

Hello Battalion Hawk Bloggers,

Thank you for another thought-provoking comment on my comment.

One slight correction, I have only scanned between two and three thousand photos and negatives so far. I’ve owned digital cameras for about ten years. Because it costs virtually nothing to take digital photos, most in my collection are digital. With many negatives and slides still to be scanned, I will probably be preparing another two or thee thousand photos.

How long did it take?

I hadn’t really thought about the time taken to scan and process negatives, photos and slides so I ran a little test. I scanned a set of 34 negatives with a stop watch keeping time. They took 58 minutes from start to processing and adding to iPhotos. That is an average of about 1 minute 40 seconds per photo (100 seconds).

You know I like working with numbers so I next worked out the time 1,000 negatives would take. It would take 100,000 seconds. That is about 1,667 minutes or about 27 hours 45 minutes. Of course I don’t scan these all at once as there are other things to do in the day so a 1000 scans would be done over about one week.

Here are two photos from the timed scans. While the quality isn’t as high as modern digital photography, they brought back memories of a weekend I organised for children from my school to visit an old gold mining town named Hill End. The first shows the town and the second a place known as The Golden Gully where people digging and panning for gold were the cause of large amounts of erosion.

Family History

I love the idea one of you has a speeding ticket as a memory of being a baby. I have nothing so unusual, only photos. 🙂

It’s very true, family history connects us with the past and if we could go back far enough we would find every person in the world is a distant relative. You would probably have seen this before but in July, 2012 I wrote a post about Genealogy (family history). In it I showed the numbers of relatives would be impossible unless we were all connected through time. Here is the link…

We're All One Big Family


Our memories can be like  a movie from the past as we remember our experiences but the movie has sometimes big parts missing.

My first memory goes back to when I was about two. I can remember walking out of our laundry, falling over and crying but I couldn’t remember at the time the doctors found I had a slight problem with my legs and I had to wear a brace to correct it. My patellas (kneecaps) needed repositioning.

The next memory is of being three. I was sitting on our large dining room table. My mother had been cutting beans but had to get something from the kitchen. I wanted to help so I picked up the sharp knife and cut my thumb. I still have the scar.

The time in between these two memories was blank but photos can fill in some gaps. When scanning a recent batch of photos I found this one taken of my mother, older brother and me during the in between time…

This photo is not to be used without written permission.

Location: Unknown

Can you see it shows me what we looked like back then, how we dressed and what we were doing? Without the photo, I wouldn’t have any memory of that day in 1957 but one more section of my life movie has been added.

Old Cameras

Danny’s family friend would have a very interesting camera collection if it includes one of the first cameras ever made. I suspect it could be something like a glass plate camera. They were big and used glass plates coated in chemicals. Here is a Wikimedia Commons image of a glass plate camera.

Photography by: Frank Gosebruch

I also found a number of glass plate camera photos on Wikimedia Commons…

This image is of the Ipswich Photo Society in Queensland, Australia and was taken in the early 1900s.

This image is in the public domain.

Making Change

Making change doesn’t only mean working out what coins to give someone when they buy, the money itself can change over time. I can see why Mrs. Renton isn’t happy about not being able to use an old song that has worked so well.

For Australia, there is talk of another change, the end of our 5c coin may be in our future. We already round up or down to the nearest 5c but, if the 5c coin ends, we will be rounding up or down to the nearest 10c.

When I was your age, Australia didn’t use dollars and cents. Like England, we had pounds (£), shillings (s) and pence (d).

Twelve pennies (12d) made a shilling.
Twenty shillings (20/- or 20s) made a pound.

On the 14th February, 1966, Australia changed to decimal currency. Our coins were 1c, 2c, 5c, 10c, 20c and 50c. Out notes were $1, $2, $5, $10 and $20. A $50 note was issued in 1973 the $100 note in 1996. We lost the 1c and 2c coin in 1992. The $1 coin came in 1984 and the $2 coin in 1988.

An international group of classes are taking part in an online activity known as “Our World, Our Numbers”. One activity looked at the different currencies of each country. When the Australian class wrote of their money and compared it to others, I wrote a post for them showing the money I grew up with.

Copyright and Sharing

It is important for people to be aware of the need to give credit. I know two companies very strong on protecting their rights are Disney and Apple. For them and many others, what they create, whether as ideas, words, art, music or inventions, is the way they make money.

In my case I don't set out to make money from most things I do. My payment comes when I find people enjoy what I share or find it useful. Under most of my photos I add a message saying the photos can be used by schools and students. Sometimes, as in the family photo, I restrict permission to needing written approval to use them as I don't wish them used.

I'll share one more graphic on this post. On another of my blogs, I was writing a short, fictional 104 word story for a writing group. In it I wrote of a humpback whale named Solana. While they can be seen along our coast, I didn't have a decent photo of my own so I drew one using Photoshop. As it hasn't appeared on this blog, I thought I would share it with Battalion Hawk Bloggers...

Making the World a Better Place

Hello Battalion Hawk Bloggers,

When seeing world globe graphics they so often centre on more equatorial countries. I had decided to create world globe graphics from different perspectives (ways of looking). The first graphic I created was placing Canada at the top of the globe because I was writing an extended comment for you.


There are now over 38,000 photos in my iPhoto library's photo section with a few hundred more negatives to scan before I start scanning 35mm slides. During the process I have discovered long lost photos and negatives. It's part of a discovery of the past. At one time, I found an old tin and opened it. Inside were photos measuring only 3" x 2" (7.5cm x 5cm). The photos included family members as well as photos of people I couldn't identify. There were also negatives needing changing to positives.

Long Lost Memories?

Probably the best memories come when you find photos of relatives no longer with us...

This graphic should not be copied.

1. My maternal great grandmother, i.e. my mother's grandmother. The photo would have been taken around 1930.

2. My maternal great, great grandfather, i.e. my mother's mother's grandfather. This photo was probably taken around 1900.

3. My Maternal grandparents, i.e. my mother's parents. This is a photo from 1958.

4. May paternal grandparents, i.e. my father's parents. Probably taken about the same year as 3.

I never met my great grandmother or great, great grandfather. Photos therefore are a journey into history where we can meet  people from the past.

Being Positive not Negative About Photos

Before we had digital cameras, we used film in cameras. Film was a roll of plastic coated with chemicals. It was inside a film container so light couldn't change the chemicals. When film was in a camera, you closed the camera to keep light out then wound the film to the first position (frame). When you pressed the camera button, a shutter would open and close. The moment of light would react with the chemicals and change them. You then wound to the next frame. When the film was used, you would rewind the film into its container and take it to a camera shop or process it yourself.

I know many of you may not know what negatives are. They were what appeared on plastic film when we took photos. Either through a camera shop, or your own equipment if you had it , you would open the film roll in a dark room and put the film in a chemical bath. This would make the film (negatives) safe to see in light. With the negatives now safe, it was time to make your photos. This was done by projecting the negative onto chemically treated paper. The light would change the chemicals on the photo paper. Another chemical bath, this time for the photo paper, made the photos safe to be in light. After the photos had dried, you could take your photos out of the darkened room to show to friends.

Below I have simulated two types of negatives and photos so you can see what they looked like. The first is a black and white photo from 1940 and shows the negative on the left and positive on the right. Do you notice they are opposite? Dark on the negative becomes light on the positive.

Now look at this next pair. The top shows how a colour negative would look while the bottom would be the print.

Do you notice blue on the negative becomes yellow on the positive?

Can you see what colour red on the photo looks like when you look at the negative?

Nuevo Sol, the Peruvian Currency

Knowing some words in Spanish may have helped me know this meant "New Sun" but it didn't help me know why their currency was thus named. I did a little research.

Before the Nuevo Sol was introduced, the Peruvian currency up to 1985 was the Inti but inflation became very, very bad in Peru. Just by chance, amongst the few international currency notes in my small collection is a Peruvian 100 Inti note, the money before the Nuevo Sol. Here is a scan of both sides of the old note.

As this is no longer legal tender, it should be acceptable  for schools and students to use this graphic for non-commercial, educational purposes.

The government replaced the Inti (Sol) with the Nuevo Sol. The exchange rate was 1 Nuevo Sol = 1,000,000 Inti so this means you would have needed 10,000 of these notes just to get 1 Nuevo Sol. This note was practically worthless.

I checked and found Inti was the name of the Inca's sun god so Nuevo Sol is a good name as, in a way, it means New Inti. Here is the link  with the information I used...

Peruvian Nuevo Sol

With Nuevo Sol not worth as much in Canadian dollar, you would expect prices to appear higher but, in real terms, the prices probably aren't that different when you consider you have more Nuevo Sol. Converting Canadian dollars to Nuevo Sol, you might find some items cheaper in Peru because people are, on average , not as well off as the average Canadian.

Just checking today's exchange rates, $1.00 Australian = $1.06 Canadian but when you look at the fees for exchanging Australian dollars to Canadian, our currencies are about the same.

Just an added thought, your $830.45 would have been worth about 2,099,970,000.00 Intis before the currency changed to Nuevo Sol. That is two billion, ninety-nine million, nine hundred and seventy thousand Intis. That would have meant just $1 Canadian would have been worth  2,528 713.35 Intis so if you had a dollar, you'd have been a multi-millionaire in Peru in 1985. Can you imagine the price for a can of soda? Life would have been very hard for the Peruvian people. Savings would have become worthless. I think I would rather have Nuevo Sol.


Quotes and Being Quoted

If I use something said or written by another, I always try to add a credit for the writer after a quote. It's only fair. Unless you see credits for a quote in my posts, they would normally be my words but I know some people can pretend they first used a quote. When we use the words of others and pretend they're ours, it's called plagiarism.

On December 7 last year I wrote an extended comment when you discussed the marvellous book, “If the World Were a Village”. After sharing my ideas and reading your wonderful comments in that post, I wanted to sum up my thoughts on what had been discussed. At the end, I wrote...

One world, one village, one family… Together, hand in hand, we can achieve great things.

It can be a good skill to summarise information in brief sentences so others find it easier to remember.

Receiving the Parcel and Snail Mail

I thought I would finish off this comment with a picture rather than a sentence.

(I think the Battalion Hawk Bloggers might understand the blue words in the picture.)

"Our World, Our Numbers" is a mathematics collaboration project involving 7 classes in 5 countries. The first post was from 4KM and 4KJ in Australia

Australian Currency

Dear 4KM and 4KJ,

A second of your posts for 2013 started me thinking in different directions again.  Did you know when I was your age I used different Australian money to what we have today?

When I was your age, we used pounds, shillings and pence, not dollars and cents. I have some pictures of the money down below. There was also a £10 (10 pound) note but I don’t have one in my collection. While we aren’t allowed to copy our modern money, I think these are okay because the last time they were used was in 1966.

You can click on the pictures to enlarge them.

From left to right...


half penny (ha'penny) equal to about half a cent

penny equal to about 1 cent

Three penny - 3d (thrupence) equal to about 2.5 cents


Sixpence equal to 5 cents

One shilling - 1s equal to 12 pennies and became 10 cents

Florin - two shillings equal to 24 pennies and became 20c

10 shillings - half a pound - 120 pennies - became $1

One Pound - £1 - 20 shillings - 240 pennies - became $2

Five Pound - £5 - 100 shillings - 1200 pennies - became $10

There was a 10 pound (£10) note but I don't have one in my collection. It became $20.

When these pounds (£), shillings (s) and pence (d) were in use and I was your age, my father earned about £20 (20 pounds) a week. That was enough to make payments on the house and car, buy clothes and groceries, save some and go on holidays. That is $40 in today's currency. My pocket money was 1s (one shilling or ten cents) a week. Prices were much lower than today but we earned much less. The money shown above would have been about one third of my father's weekly pay yet it was only £6/13/10 ($13.38). Click below to hear how the money was said...


On the 14th February, 1966, Australia started using decimal currency. We had 6 types of coins and 5 notes. At that time, all notes were paper and not the plastic we use today.

Coins:  1c, 2c, 5c, 10c, 20c, 50c

Notes:  $1, $2, $5, $10, $20

Here are pictures of the 1c and 2c coins plus $1 and $2 note no longer used. Australian coins have the face of the ruling monarch on the opposite sides, i.e. Queen Elizabeth II since her coronation in 1952.
