How to photograph distant objects (10km)?

You can't. I don't care what you've seen on CSI, this just isn't possible in the real world. Even taking Canon's ridiculously big (and now discontinued. Oh, and $100,000) 1200mm lens, The Digital ...

How can a smartphone take pictures of a landscape with everything in focus?

It's worth noting that sensor size plays a huge role in depth of field and behavior of the lens. A smartphone has a tiny camera sensor, often around 25 square mm. This gives the camera a crop factor ...

Why in a photo light lines of street lamps? How to remove them?

How to convey a sense of depth & distance in a landscape?

If we start by just numbering them 1 - 6 for easy reference... Personally, I'd discount 5 altogether as it has none of the aspects we're looking for. 2 is a bit naïve & perhaps achieves a lot of ...

Why am I getting a small black patch when I take photos?

To investigate sensor dust, perform the following test: Close your aperture as much as possible (high F-number). This makes the sensor dust more visible. Increase the focal length as much as ...

How to photograph distant objects (10km)?

By specifying that you want to do your surveillance photography in "good sun light", you have already shot yourself in the foot. The best time to do this kind of photography is at night or in the very ...

Why am I getting a small black patch when I take photos?

There's probably something on the sensor - maybe a dust particle. You can check if the Canon camera has a sensor cleaning option and use it or take the camera to a local repair shop and have the ...

How can I take advantage of the transparency of water in a landscape photo?

You'll want to use a polarization filter. Rotate it until you get the effect you want. By the way, make sure you get a circular polarizer (most modern ones), the older linear polarizers can confuse ...

Why do people not use large f-numbers (small apertures) when shooting landscapes, when you want large depth of field?

First people want to have (when making photos of landscape) almost all in focus. But they do not use F22-32 because on such aperture diffraction degradate the quality of images. Second, when shooting ...

What's the difference between "Fake HDR" and real, bracketed exposure HDR?

What's the difference between “Fake HDR” and real, bracketed exposure HDR? The only difference is how broadly or narrowly you decide to define the term High Dynamic Range Imaging (HDR). Do you use ...

How can a smartphone take pictures of a landscape with everything in focus?

If by "landscape" you mean something like this: then the answer is simple: at very large distances, depth of field is extremely large even at large apertures. That is, at any aperture if you focus at ...

Why is 16:9 aspect ratio rarely used in professional photography?

I expect that this is mostly due to technical limitations. DatAperture wrote it very nicely on Reddit: Lenses project circular images. To get the most resolution out of a lens, you should use a ...

Landscapes: why *narrow* aperture?

Or am I misunderstanding how aperture works?...I thought the further away something is, the greater the depth of field. So when an object is three and a half miles away, it's going to have a huge ...

What are the practical advantages of fast lenses when shooting landscapes?

When used at the same aperture and focal length, a faster lens will have less vignetting than a slower lens. For example if you choose to shoot at 35mm f/4.0, then a 24-70mm f/4.0 lens will have the ...

Why are my dSLR-shot landscapes consistently overexposed vs. the same shots on my smartphone?

I think what you're really seeing is the difference between 'photography' and 'computational photography'. Nothing I can see in the first photo hits 0,0,0 or 255,255,255, it all fits quite neatly ...

As others have said, 10 km is not feasible due to the physics of light and atmospheric distortion. However, I'd like to address another aspect of this that hasn't been mentioned yet: if someone is ...

What are the practical advantages of fast lenses when shooting landscapes?

A faster lens (= low F-stop) allows easier manual focus and better auto-focus, given the camera has AF sensors which can exploit faster lenses. For landscape however, there is usually enough time that ...

How can a smartphone take pictures of a landscape with everything in focus?

Aperture is only one factor in depth of field. Others are: sensor size and focal length. Large format camera lenses often have max apertures in f/4-f/5 range, yet they yield very shallow DOF - because ...
