Why do people keep telling me that I am a bad photographer?
In general, I do not like taking photos much. But I have some female friends, including my flatmate, who I hang out with and they love taking photos and they always ask me to do it. However, all of them commonly say that I cannot take nice photos…

Can a smaller sensor's "crop factor" be used to calculate the exact increase in depth of field?
If APS-C and similar crop-sensor digital cameras have a focal length multiplying effect such that a 50mm lens has an apparent focal length closer to the field of view of an 80mm on a full frame camera, and yet at the same time the depth of field for…

Why doesn't the picture become darker the more you zoom in?
As your lens's focal length gets longer, fewer photons pass through the lens to hit the mirror/sensor.
Why don't you see darkening when you look into the viewfinder and zoom in with a zoom lens, and brightening vice versa?
Why don't telephoto…

What technique is used on old technical brochure pictures, which look like a "polished" or "smoothed" rendering?
I'm seeing a lot of old picture from probably 19xx till 1970 which have such a clean perfect look. For a better explanation, I added two examples. As in the comments mentioned, the second one is probably a painting. But sometimes those pictures are…

Should I horizontally flip a client's portrait?

Why don't compact digital cameras have the aperture range of DSLRs?
Why is it that on compact digital cameras the aperture never seems to go any smaller than about F8 ? Even on high-end compacts such as the Canon G10 or Panasonic LX5. Is there some practical or physical limitation due to the size of the camera or…

Why is the aperture ring removed from new Nikon lenses?
Maybe I'm wrong, but I notice that Nikon's newer lenses don't have an aperture ring. For example, an older AF 35 mm f/2D is now replaced by AF-S DX 35 mm f/1.8G, or AF 50 mm f/1.8D is replaced by a newer AF-S 50 mm f/1.4G.
I never used a D-type…

In last week's issue of the New Yorker, Rebecca Mead wrote:
The last facility that processed Kodachrome film, which many mid-century photographers used, ceased to do so in 2010. An undeveloped roll of Kodachrome found in a late photographer’s…

I have several thousand images taken with a GoPro that are upside-down.
I'm looking for a way, an app really, that can flip them all, 180 degrees, in one operation.

Why don't more people use fisheye lenses as a cheap wide angle lens?
From my understanding, a fisheye lens usually has a coverage of 180 degrees or close to it. Given the extreme coverage and the availability of software that can turn fisheye images back to a rectilinear perspective, why are fisheye lenses not more…

How do I make sure my RAW files are readable in the future?
I've recently started to use RAW with Lightroom. I'd like opinions on how I should make sure my images are readable (not necessarily editable) a few years hence. Heck, let's say a decade some decades.

How does the human eye compare to modern cameras and lenses?
A goal in most photography is to present a scene which resembles what a person who had been there at that moment would have seen. Even when intentionally working outside of that, human vision is the de facto baseline.
