Stitching worked well. I think I have seen both of those ships. Many of us probably have I suppose, whether we are aware or not...

Thanks for comments and thanks to others who liked the ships.
I’m getting a bit cleverer now at knowing how to select parts of images to ‘Photomerge’ in CS6.
I download my shipping pics on ‘marine traffic.com’. I’ve got about 3000 pics posted but voting is a bit slow due to their difficult voting rules. I need about two hundred more votes for an upgrade.

... I couldn't be bothered to change the lens and risk getting dust on the sensor. Has anyone considered using a clear, clean plastic for lens changing - a bit like going back to the 1950's when changing film.

How about putting the camera/lens into a plastic bag every time you zoom? :-)

By the way, I have a Sony RX100 which does not have a removable lens, and it has dust on the sensor.

And perhaps evacuate the bag with a vacuum pump - eh?

Unless you are in the middle of a haboob, I wouldn't worry too much about getting dust on the sensor in the 20 seconds or less that it takes to switch lenses. Keep the lens horizontal and the camera either pointing straight ahead or downwards if you are still concerned.

If I don't get the shots I want with the gear I have, the only optics I need to examine is the mirror on the bathroom wall. The root cause will be there.

Sam, I think that there is small degree of humour creeping in here.

I just thought I'd post a picture a bird in case I get thrown off this thread.
Not as exciting as you guys down under seem to post or our best buddies with a special relationship across the pond.
I must tell you about a local pond which was home to a pair of Mandarin ducks. I went to grab a shot of them and the owner said a fox had just eaten them. Aaaah! So sad!

Nah, didn't mean to. And if it did, I mean it in the best possible way, of course, in keeping with the ethos of POTN.

question, when you guys are out in the field. In any condition, do you put on a protection filter?
I currently do not, but my trip out to west of Ft Worth, it was dusty and windy. My front element was pretty dusty when I came home.

what are the thoughts of a protection filter. I was looking at Hoya HD protector. I have some coupons on amazon, so it would be very low cost.
Thoughts?

When I was first starting photography (about 8 years ago) I put protective filters on everything. Over the next year, I noticed that the filter would sometimes (ok, rarely) ruin a shot. I also realized that a zoom lens (one that extends and contracts) is pumping a lot of dust through the lens and camera all the time. So I stopped using the lens filter and carry a cloth and a LensPen. No issues in 6+ years of not using a protector.

My story is similar. I stopped using protective filters when I started using actual filters. Taking them on/off was a pain. I just kept one filter in case I need it to complete the weather sealing on a lens. Heck, I don't even use hoods as often as I used to. Modern L lenses are quite flare resistant.

I pretty well never use a filter. Rarely I use a polarizer. Almost always use a hood except with macro work.
