That moment when… you see one of your photographs in commercial use for the first time!
I was doing a Google search for ‘Caroline Grubb’, looking to see if my new Caroline Grubb Photography website (unofficially launched yesterday but still very much a work-in-progress) had been found by the Google bots yet and if it would come up in a Google search.
Finding that it hadn’t come up in the search, I moved on to search for ‘images of Caroline Grubb’ out of curiosity to see what information the World Wide Web might have on me.
It was then that, in a moment of great surprise and delight, I found that my image of an hibiscus flower – taken on holiday in Borneo in 2013 and published on my Flickr site – had been chosen as the headline image for an article about voting for Malaysia as Asia’s leading destination by Zafigo.com, a website for ‘the woman traveller in Asia’.
The feeling was followed with pride and relief that the site had credited me with the photo (sadly the photo credit link doesn’t work).
Although the article was written back in 2017, this is the first time I’ve knowingly had a photograph of mine published. A small but important landmark for me. Hooray!
I knew that the “two-thirds” sensor, common in compact SLRs, has a magnifying impact on an image compared to the “full frame” sensor found in the mid-size and pro SLRs, but I’d never seen the effect of this 1.6x magnification with my own eyes until today.
This post compares photos taken on Dave’s Canon 5D with a EF 17-40mmm lens vs my Canon 650D with EF-S 18-200mm lens.
Test 1 – Wide angle
The “two-thirds” (22.3mm) APS-C sensor in my 650D has the effect of magnifying an image by 1.6x compared to the “full frame” (36mm) sensor of the 5D, meaning that at the same focal length my camera can’t fit as much into the image as it’s big brother. Both these shots were taken at each lens’s widest angle (17mm vs 18mm respectively).
Notice, for example, how the bench and flower pots in the foreground are complete in the first image, but cropped in the second one:
Test 2 – 40mm focal length
The next test shows a flower taken at 40mm focal length on both cameras. You can see the magnification effect again on the 650D as less of the house in the background is visible compared to the 5D.
I guess I’ll no longer brag about how my 18-200mm lens is a ‘wide angle’ lens any more then!
