Katy, at the Littlest Thistle, is holding a Camera Challenge.
The second assignment was about understanding aperture.
This was an assignment and a half!
I took hundreds of photos of objects all lined up:
But rejected them all!
Until this morning, when I hit on the idea of lining them up with the focus points on the camera, and then manually changing the focus point from one to the other as I moved through the series. That way I didn't have to move the camera, just the settings.
The only setting I changed in each photo was the aperture priority.
I labelled each photo with its colour (for identification) and f number. Violet is on the left and purple on the right. I won't bore you with red and green; they don't add anything.
Here are nine photos, plus a bonus!
|What are those mysterious light spots on the purple spool?|
Reflections from my watch, necklace, wedding ring ...?
Camera: Canon EOS 450D
Lens: EFS 18-55mm
Exposure adjustment: +1 (a mistake, but I'm not doing them all again!)
Light balance: auto
focal length: 18mm
Interesting is that the exposure times increase as the aperture value increases. (Good job I have a tripod!)
|There are the mystery spots again.|
To be honest, I know there's a difference, but find it hard to see in this format. Probably because of the lens but maybe because the purple spool is only 14 cm/ 4.5" further from the camera than the violet. Maybe it's .jpg format that's the problem.
And finally, by way of contrast, this photo I took after a heavy shower last September with my zoom lens:
Canon EOS 450D
Lens: EF 75- 300mm
ISO: 800 (set on auto)
Aperture value: f 5.6
Focal length 210mmThe leaves are close together but the lens is different and the camera was much further away.
I'm linking up to
so go and visit Katy and see what others have done this month.
Happy snapping everyone
