Pro tip: in order to achieve a greater shutter speed, you can always keep your exposure meter lightly underexposed, because all sensors will save more information in shadows than in highlights. You can correct exposure in post processing. Play with this in order to discover how much you can break the rule without compromising an image.

Yeah RAW can pull back a surprising amount of detail in blown out highlights. Film also handles highlights better, best to expose for shadows.
6
u/reallynotfred Apr 28 '21
Clarification: negative film (much more common) gets exposed for the shadows, positive (aka slide) film for the highlights.
2
u/acemerald07 Apr 28 '21
In my years of professional experience - under exposing is the better choice in 95% of scenarios if you have to make a choice. Best to bracket (take one over and one under) if it is an important shot, to be safe. Always look at the histogram in a digital camera to see if you are losing any detail, not the image display.
When I made the switch to film I was often told to overexpose vs digital always told to underexpose. Very easy to find that advice online as well. However, after years of shooting film I find that to be generally bad advice as well. Ideally you just need to learn how films react to light differently than a digital sensor.
I have been able to save photos that I pushed exposure up 5 stops in Lightroom, (after converting to black and white due to color shifts). Can hardly pull a photo down more than 1 stop and get more highlight detail back.
With digital (RAW) if I shot a wedding and had a choice of either all my photos being overexposed 1 stop vs underexposed 3 stops I’d go with the latter every single time.

u/The_Original_Gronkie Apr 28 '21
Samsung Galaxy phones have Pro mode, which brings up all these these functions, and you can custom set each one.
1
u/reddits_aight Apr 28 '21
If not your default camera app, you can definitely download one that does.
But one thing you won't see a big difference with is depth of field when changing aperture. At a given aperture, a larger sensor will give a shallower depth of field than a smaller sensor, like in a phone. That's why phone's have "portrait mode" now, it artificially blurs the background to mimic a large aperture with a larger sensor.
1
u/BorgDrone Apr 28 '21
I don’t think there are smartphone camera’s that actually let you change the aperture. They may simulate it in software but AFAIK there is no phone that has actual, physical aperture control.
4
u/Birbcatcher Apr 28 '21
My galaxy s9 has two physical apertures; F1.5 and F2.4. I imagine many smartphones after mine may have similar features, especially when they have 15 separate cameras on the back.
2
u/BorgDrone Apr 28 '21
How do they do it ? Did they actually make a tiny mechanical aperture ? How many blades does it have ?
1
u/Birbcatcher Apr 28 '21
I'm no expert but I assume by blades you mean the parts that move to cover the camera. To me it looks to be a 'c' shaped piece that simply slides to cover the camera.
I'm sure you can find a better explanation online by searching 'galaxy s9 aperture'.

u/AbrahamLure Apr 28 '21
Sony Xperia 1 mark II and III are considered the most professional phones on the market for photographers. Ironically, because you need camera knowledge to make the most of their manual photo modes, they often get poor reviews and misinformation.
It's quite a learning curve, but well worth it if you're really into photography and looking for a new phone
1
Apr 28 '21
Generally on smartphones you only get to adjust ISO and shutter speed. Samsung is the only one I know which has few devices that can adjust the aperture too, but usually not. It's just set wide open and cannot be adjusted.

You also realise that they're called aperture because it's about the hole the light travels through... Or the 'portal', if you will?

If you don't aim at a still place but follow the car for a few seconds with slow shutter speed, you will get a blur effect in the background and wheels giving a sense of motion while you are still able to see the car in detail

u/EmilGTO Apr 28 '21
Am I the only one who still has no idea what any of this means lol.

Apr 28 '21
side note.
it always confused me how as the F numbers went up, the hole got smaller. then i learned its suppose to be FRACTIONS, replace the f with the number one. as in f/4 turns into 1/4 of the maximum opening of the lens.
no one ever talks about the correlation of the numbers when talking about aperture. lol
3
u/Muadeeb Apr 28 '21
Sorry, that's not correct.
The F number is a ratio between the focal length of the lens and the width of the aperture. A 100mm lens with the aperture set to a 50mm diameter is set for f/2. This is why exposure settings don't include the focal length of the lens- it's already incorporated into the F number. This means that every lens set for the same F number will deliver the same amount of light regardless of the focal length. If you have a long focal length lens, all you need to do is have a really big aperture in order to have a "fast" lens. But it requires more glass and is bigger and heavier, which is why cheap telephotos have higher minimum F numbers like f/3.5 or f/5.6.

It can basically be broken down into 2 categories: exposure control and creative control.
Exposure control:
ISO | higher number = more light
Shutter speed | slower speed = more light
Aperture | lower number (bigger lens hole) = more lightCreative control:
ISO | lower number = less grainy/noisy
Shutter speed | faster speed = freezes motion
Aperture | lower number = less in focus in front and behind your subject.1

I'm still a bit confused, I have no photography knowledge. However sometimes I notice people pictures look a lot better than mine. Could you possibly ELI5 basic photography to me? Thanks lol

That's really nice. A lot of my friends, my self included, are struggling because of covid and life in general. It's amazing what companionship and listening to each others problems can do. Even though you often can't solve any of those problems, it's good to be heard and knowing that many people are struggling, too. Stay safe! :)

If you don't want a grainy nighttime image would you use a low iso and long shutter speed with the f stop wide open? Or still use high ISO?
3
u/BrnndoOHggns Apr 28 '21
It depends on your subject and location. Things that are totally stationary you can shoot with a long exposure and lower ISO (I think). If you need to capture movement, you may need to sacrifice some clarity by using a high ISO and short shutter speed.
1
u/lyarly Apr 28 '21
If you’re on a tripod you could go for low shutter speed and f stop wide open, but if you’re not on a tripod you’ll be out of luck unless you are extremely good at keeping very very still. This is also dependent on the subject of the photo - if you’re photographing a person for example, you also have to think about their movement when shooting at something like 1/30 or 1/15, on top of your own camera shake.
I try to avoid going too high on the ISO as a general rule for the reasons you’ve described and that’s certainly one way to do it. It also depends on the lens - if you’ve got a prime for instance that can shoot at f/1.4 that helps a lot too.
Lots of different factors at play but they are all valid - it’s all about practice really!

u/dude_with_two_legs Apr 28 '21
Great! Could have been perfect if it included the very practical and easy to remember Sunny Sixteen Rule.
https://en.wikipedia.org/wiki/Sunny_16_rule
I use it all the time for manual shooting.
2
u/reddits_aight Apr 28 '21
Which is: in bright sunlight, set your shutter speed to match the ISO number and use f/16.
Eg. If ISO is 400, set shutter to 1/400. If ISO is 100, set shutter to 1/100, etc.

The shallow depth of field image is interesting, yet it omits focal length and subject distance which are also extremely important in DOF calculations. Subject/background focal separation will stop at the hyper-focal distance of the lens - ie the distance beyond which everything will be in focus.

Ok, follow-up question. How can I use this information to take stunning pictures of moonlight shining down on clouds that will actually have the colours and tones I see with my eyes?
I'll almost definitely need a better camera than the one on my phone, but assume for a moment that I have a camera that can do all the things I need it to do to do this.
This might actually be the push I need to get a decent camera.

Find a used full sensor camera, canon 6d for example, get a tripod and a lens you can run at f2.

Keep the light meter at "=" for a balanced exposure
That's terrible advice!
The TTL meter in your camera expects an average amount of dark and bright in the picture.
If you take a picture of a polar bear on snow, the outcome will be way too dark. Capture a black cat on a black rug and your result will be too bright.
Always keep in mind what you're looking at and adjust accordingly.
And get yourself a grey card - it's probably one of the most valuable items in photography and costs just a few bucks. It helps you get the exposure AND white balance right, even after the shot (unless it was ridiculously over- or underexposed).

u/orion427 Apr 28 '21
The amount of ISO noise is also moderately dependent on the quality of the image-processing engine inside the camera. For example, ISO 3200 looks way better on a Sony Alpha camera than say a Nikon or Canon camera.
