Comment Post #286820 Maybe the last one looks less bad because although the hands are in an unnatural pose, at least the visible wrist is fairly straight. The left wrists of the other two subjects are bent to an extent that rarely happens spontaneously except possibly when playing a backhand stroke in a racquet sport, an...

Comment Post #277407 Fast enough shutters speeds [do exist](https://www.youtube.com/watch?v=VgjyPmFKxCU), although the gear in question certainly couldn't be described as prosumer. It may be possible to rent it, although all of the rental sites I've looked at have contact details for a quote rather than actual prices.

Comment Post #281609 On the subject of the sensor, an important point which you omit to mention is size. A 35mm sensor in a camera can capture a lot more light than a 10mm-or-so sensor in a phone, allowing either larger sensels (which is good for low light performance and reduced leakage) or higher resolutions (although ...

Answer A: Program to strip EXIF data from images
exiftool It's available as a standalone application for Windows, and in package distributions for Linux. You can remove all EXIF data from a JPEG with exiftool -all= path/to/file.jpg or you can be more fine-grained in the tags you choose to remove. The option `-ext jpg` will cause it ...

Answer A: 2020 - November - Animals
Low-key photo of a small deer with large eyes Kirk's dik-dik (Madoqua kirkii), Bioparc Valencia, February 2017. Taken with my Nikon D5300 and 1100mm f/11 reflex lens at ISO 250 and 1/800 sec. I like to consider this photo as proof that the "donut" bokeh of a reflex lens doesn't always ruin a ph...

Comment Post #278499 @dustytrash, so make it a good tripod with a hook for weighting it down. If a tripod tips over it's either underspecced for the camera, badly set up, or in high winds.

Comment Post #278940 There is software which will automatically align photos for panoramas: I use the free Hugin. Exact alignment is good if you can manage it (and a spirit level may help), but the biggest problem will be having exactly the same focus, and I can't offer any tips for reproducing the focus position on a sm...

Answer A: How can I take better pictures of the fish I catch?
> ...it's always kind of awkward to hold a slimy fish in one hand and a camera in the other. If you put the camera on a tripod pointing down, you free up a hand. This would also potentially let you set up a white background with a ruler to show how large the fish is. Taking this to extremes, if...

Answer A: Procuring a lens cover for large (133mm) lens?
> I'm not quite sure how to make one that will be as resistant to impact or scrapes as an engineered one. Many large lenses are sold with fabric "socks" as their only protection, so you may be worrying unnecessarily. I personally have a Sigma 300mm f/2.8 which I acquired second-hand with no cap...

Answer A: What are shutter speed, ISO, and Aperture?
Shutter speed Shutter speed is the inverse of exposure time: i.e. it measures how long the camera collects light. This is the parameter with most flexibility: most cameras support shutter speeds at least as fast as 1/200 seconds and at least as slow as 120 seconds. A short exposure time is desi...

Comment Post #277201 I've redone my diagram, and I had incorrectly placed the virtual image of the reflected flame. Angle estimate revised to 9 degrees. But even head-on the total intensity reflected is about $0.04 (1 + 0.96^2) \approx 7.7%$.

Comment Post #277201 Nit-pick: I don't think 1% is generous at all. Fully head on, glass reflects about 4% of the light from each interface; I estimate the angle of incidence of the light from the top candle to be 30 degrees (assuming distance candle-window approx. height of candle, since reflection approx 1/3 candle bel...

Comment Post #277043 You're not going to get a good photo *of* Luna with a mobile phone because their optics are configured for wide angle shots, but you might be able to get a nice landscape with the moon in the background.
