Yes, I have suffered similarly trying to photograph swallows, but at least you succeeded sometimes!
Actually I like the collection. Their slightly disjointed angles and backgrounds help convey the problems and slightly masochistic fun of trying to photograph them.
I would not have known it's an airport without your title. But even with the title, the image still doesn't say "airport" to me. Which means that the title implies "flying" in another sense, as though the figures might levitate out of that interesting space. Provocative and intriguing.
I have taken many photos of this view. In full sunlight there is not a lot of variation in the greens and they have never appealed to me. In this bright overcast light, I noticed a lot more variation. There are predominantly two species here, box gum and spotted gum, the box being the lighter green (or it may be the other way - I will check tomorrow). I am never quite sure where to get focus in these sorts of pics - advice welcomed.
The cicadas have been prolific this year. There are many species, and quite large for insects being about 50mm long. They are the loudest insects known, having a membrane on their stomachs that they vibrate to attract a mate. When they are all calling at the same time it is actually quite deafening. I think they are in all continents so I may not be relating anything new...
And finally one I have been trying for a lot, although I still haven't quite nailed it. It took a lot of bursts, mostly with nothing in the frame, or otherwise totally oof, to get this shot. This is an Australian Emerald. They hover just enough to make it possible. Their eyes seem to change colour in the light and in the brief moments I have seen one clearly, have a nice deep metallic green.
No - you can buy a screw-in infra-red filter - the Hoya R72 is an example. This will allow you to experiment with IR just to see how you like it. Then, if you really like the effect, you can think about having a camera converted. Over the years, I’ve had two - a Nikon D70 and currently a Fuji XE-1. I bought both of them second hand already converted for less than the price of the unconverted camera and less than the cost of conversion. There are two caveats, though: the screw-in filter is very dark, which means long exposure on a tripod (or very high ISO settings) and, though you can obtain a wide range of effects, including arresting ‘false colour’ images, quite a lot of post processing is required.
All depends on what you wanna spend or do. Sony's got some old cameras you can "hack" with a magnet, there's a ton of older models that are capable of being DIY projects, or you can spend money and get something with more professional options. Any way you slice it, you need a IR filter, which, as @WolfsHead pointed out, you can use on any camera with enough time, but lens choice matters, sensor size matters, and subject matter becomes very limited.
From an aesthetic point of view it's a good photo, and at first glance we'd say it's an innocent interaction between a human and an orca, but that's only side A of the story.
The B side is THIS : Keeping wild animals in captivity so that humans can appreciate their beauty and abilities, or just to satisfy their curiosity, is a selfish and very cruel act.
I think the bird knows more than we give it credit for and is perched in just the right spot, already receiving some warmth from the sun's rays as they reach into that vast cavern. Nice timing to catch that light as I am guessing it doesn't last too long - but you probably knew that.
Is that a cartoon effect? It looks like a scene from one of those paper cartoon magazines that I haven't seen for decades. The jacket looks good if the skin tones are a touch over done. He's doing alright though - looks like someone has dropped him a gold ingot for his efforts...
