Blurred vision

Vision changes with age. If you have shortsightedness it can sometimes get better because your eyeballs can shrink with age, that means the image hitting the retina at the back of the eye comes back into better focus. On the other hand the lens in your eye can start to stiffen and the muscles around it don’t pull on it as well as when you are younger. So the lens does not focus as it used to. This is called presbyopia and tends to affect people over forty (if I remember). Hence vision can change with time. Worth getting an eye test?

Moth/butterfly

I was looking at this tiny moth or butterfly and decided to take a photo. Not easy without a macro lens. I had to get close enough to take a photo but if I got too close it wouldn’t focus. So I moved away a bit, zoomed in a little bit and leaned on something for stability. (I have a shaking arm and camera shake is an ever present problem). I used the sharpness tool on my phone (only about 2%).

The moth/butterfly is about 2 centimetres wide at its widest part. Pale brown and white. I couldn’t see any antenna. Do moths rest with wings spread out, or closed, that’s why I’m not sure.

Hubby drawing

He’s still colouring in the book although it’s 2.30am. So I did a very quick sketch of him drawing (five minutes). He’s got his own style. But that doesn’t matter. It’s the fact that he’s doing it which is good. It gives him focus and flow. It’s great to see him doing it.

I just watched a programme about the life of the artist Bob Ross and how he taught art in America in the 1980’s & 1990’s. He sadly died at a young age.

Art is sometimes therapy. It is a good thing. I would encourage people to take it up.

Annular Eclipse

There was an eclipse today in some parts of the world. Not here though. This was an annular eclipse, where the moon doesn’t fully cover the sun and leaves a ring of sun shining behind the moon.

So why does this happen. In normal eclipses the moon appears to be the same size as the sun so its completely covered. That is because the moon is something like 40 times smaller than the sun, but also 40 times closer to us. So they have the same apparent size in the sky. But with an annular eclipse the Sun can be slightly closer or the moon slightly father away. Why? Because the Earth rotates round the Sun in an ellipse, which is an oval with two focal points. The sun sits on one focus, but the Earth orbits around both. That means sometimes it is further away from the sun and sometimes closer Then it also means the moon is further away from the sun or slightly closer to it. The moon rotates round the earth in the same way in an elliptical orbit. So sometimes it is closer to, and sometimes further away. If you add the two positions up further to the sun and further away from the earth you get an annular eclipse.

I can’t explain it more clearly. It is most difficult to think your way through how it works but I hope this makes sense.

Ice

I just took this photo, you can photograph anything and get an interesting result. In this case I like the way the cartoon cats surround the block of ice and almost seem to glow.

My tips for photos?

Look first. Even if you are seeing something through a lens look at it to see if you are including things you don’t want.

Don’t be scared to crop your photo. Got a streetlamp sticking up in the sky? Crop it if you don’t want it.

Don’t filter too much if you can help it. Once you start adjusting colours it’s hard to find the right balance. Sometimes you have to, but don’t over do it.

Use your on screen focus if you have it. If you can see something interesting you can us the focus option to just select that area. It also changes the depth of field.

Bubbles

I fill a large plastic bottle of water from the tap to water my houseplants. It had the advantage that I can reach some of the pots that are a bit out of reach for me.

This morning I saw all these tiny bubbles in the water. Air must have been dissolved in the water and had condensed on slightly rougher places on the surface of the plastic.

The blues and greens are from the tiles and paintwork in the kitchen. The shape of the bottle, with its swirling curves, adds to the interest. The bottle also acted as a lens and I like the contrast in the focus, making the bubbles in and out of focus.
