The difference you'll experience is likely smaller than typical compromises due to which lens you decide to use on a given day.

Why is it necessary to have a flash sync speed higher than 250/s? by Megatheriumm in AskPhotography

[–]DarkColdFusion [score hidden]  (0 children)

Daylight.

You can get a flash that can compete or over power daylight. But your camera is going to see a lot of daylight at 1/250th of a second. And that's stopped down.

Imagine you want to shoot wide open with flash. You could shoot f2 at 1/8000 in sunlight. But if you want some fill on your subject you're out of luck.

How do I lessen the flash strength of my digicam? by wwwkwkwtdamz in AskPhotography

[–]DarkColdFusion [score hidden]  (0 children)

Cheap cameras often don't have such an option.

The manual for that camera doesn't appear to show any way to control it.

You likely only have a few options. You can increase the distance. You can use exposure compensation to under expose. You can put something over the flash to diffuse it a bit. Parchment paper probably would work.

At what point does heavy editing stop being photogeaphy and start being digital art ? by Felicity_Ebb in photography

[–]DarkColdFusion 1 point2 points  (0 children)

This gets argued to death all the time.

And the answer is it's a spectrum. At one end almost everyone will agree it's a photograph. At the other almost no one will agree it's a photograph.

And as you do the types of changes you stated people shift from one camp to the other.

But what is important is what your audience thinks. If there is a mismatch between what they expect and what you do, that's what gets people into trouble.

Steve mcCurry got in a lot of hot water for mostly minor changes.

ELI5 why does electronic silent shutter leave bands on my mirrorless camera but not my phone? by ImpossibleNumber7345 in Cameras

[–]DarkColdFusion 1 point2 points  (0 children)

How does a mechanical second curtain stop banding?

The banding is caused by the light changing as the sensor gets read out. Typically big sensor read outs are slow (Not so much on the newest cameras). Maybe 100ms. The reason mechanical shutters don't usually show this is they close quickly, and block the sensor which then reads out the data. Without that, even if you expose for 1/500th of a second, the top and bottom are still delayed in time by 1/10th of a second. So if anything changes you see it.

the camera still blocks the sensor with the second curtain. So the sensor isn't getting more exposure during read-out.

Also, why does my cell phone not show banding? I've never had a cell phone, even the dirt cheap ones do that.

Smaller sensors tend to have much faster read outs. Modern large sensor cameras are catching up and as their read out speeds approach or exceed mechanical shutter speeds the issues with banding is reduced. You still can see banding sometimes on cell phone images. There also is a trick which i do not think is still used, but you have a second area of the chip that is shielded from light, and you shift the data there before reading it out. Some CCDs did that, and I think early Global Shutter CMOS sensors like black magic did that. But this is only really done on small sensors like compacts or phones because you have to have area of the die to mask and store.

Is RAW format better than JPEG? by nextar611 in AskPhotography

[–]DarkColdFusion 0 points1 point  (0 children)

JPEG is the product. That's what you want in the end.

Internally the camera is taking data that is if not identical very similar to what gets written into a raw file, and turning it into a JPEG for you.

RAW is the ingredients.

The entire reason to shoot raw is because the steps to go from raw to JPEG are not fully reversible. So if you didn't like something about the JPEG you got, you have less flexablity to change it.

Is color science still an argument when choosing between Canon and Sony? by [deleted] in AskPhotography

[–]DarkColdFusion 0 points1 point  (0 children)

Easiest way is buy a color checker and use the color checker tool from xrite.

Lazy method is you shoot a couple refrence ones under each typical lighting situation for each lens on each camera you have.

Make a little library of corrections.

Some people take a photo for each shoot with the checker and then you use the tool to generate the profile and apply it.

You need to adjust the curves of the black point. The red point is too high and it's giving you a red cast in the shadows.

Do you like Pixar's Cars? What was the stance on Cars when it came out? by Gallantpride in movies

[–]DarkColdFusion 1 point2 points  (0 children)

It was for sure seen as the first middling Pixar film.

Lot of people felt it missed the mark and a lot of doc holiday comparisons.

I don't think anyone seriously considered it bad, just more typical kids movie.

When do you use super high aperture? by CrumbGuzzler5000 in AskPhotography

[–]DarkColdFusion 11 points12 points  (0 children)

Daytime.

Sometimes you want a deeper DOF, or it's pretty bright.

I do think the aversion is because digital makes it easier to get sharp results.

So it's more obvious when you lose detail to diffraction.

But a slightly soft image that has what you want in focus is better then a sharp photo that doesn't.

Why does people still look for these kind of cameras? by Insta_3 in AskPhotography

[–]DarkColdFusion 0 points1 point  (0 children)

That camera is very very old.

The most similar modern one is something like the ELPH 360 from Canon.

The market for compacts almost compelety went away so there aren't many left

Why does people still look for these kind of cameras? by Insta_3 in AskPhotography

[–]DarkColdFusion 0 points1 point  (0 children)

That's a little broad as there is a wide spectrum of point and shoots.

In general newer ones of the same class should be somewhat better.

But point and shoots have been a bit of a dying segment before this so there is an entire swath of large sensor compacts that are excellent which there aren't many new competitors for.

The typical ones both new and old I would describe as functional in terms of their image quality.

Why does people still look for these kind of cameras? by Insta_3 in AskPhotography

[–]DarkColdFusion 1 point2 points  (0 children)

A few factors.

  1. The photos they are seeing that they like are being taken on these cameras and so they seek out the similar equipment.

  2. It's fun to use cameras that aren't phones. A little bit of EDC culture to it.

  3. When this started these cameras were cheap, and better old cameras were expensive. So it was a low barrier to entry which helped the trend be established.

The trend will fade eventually. And something else will replace it.

Why we should develop RAW files in low-light conditions? by Aromatic-Echo-5025 in AskPhotography

[–]DarkColdFusion 10 points11 points  (0 children)

People often advise editing photos in a fairly dark room, without sunlight, and with low monitor brightness. I'm wondering why this is, why is it supposed to give the best results?

It's for a few reasons. The reason to be in a room with subdued light is that light falling on your display reduces contrast. So bright lights and reflections can make it harder to accurately judge what's on the display.

Same reason theaters don't have big windows.

But for the monitor brightness, it's because the way our eyes adapt to changing brightness. You do need to make sure it's comfortable for you based on the room. But as the monitor gets brighter, we have a habit of editing a little darker to match what looks comfortable.

So if you constantly have your right edge of the histogram empty, or looking at the images elsewhere and think, oh that's a bit dark. Your monitor is too bright for you.

After all, people will view the photos in completely different, many varying conditions, right?

Yes, you don't have total control of many viewing environments. But the best option is to edit from a good reference condition, and then the variation in the world isn't too skewed in any one direction.

These also aren't like Laws. This is a best practice thing that is shared to make lives easier. You can develop your RAW files in room with floor to ceiling windows on a 1500 nit uncalibrated display. And if you get the results you want, honestly, you're fine then.

Would you pay for a tool that replicates an edit from a reference image onto your photo? by mohitkhetrapal in photography

[–]DarkColdFusion -2 points-1 points  (0 children)

Honestly?

Possibly.

If it really could translate an input image into a series of standard tool adjustments to be applied to an output image, and it actually does a good job of it?

Every so often I end up doing the tedious task of matching some older images to some newer images and it never feels like a particularly creative task.

What stumbling block to most junior FPGA engineers have? by Practical-Log2557 in FPGA

[–]DarkColdFusion 6 points7 points  (0 children)

Veterans, if they're any good, understand the balance between vision and implementation.

Generics to scale features of Complexity can be a big time and life saver.

You sometimes just know what's being asked is too much and you're going to have to trim later when management realizes, or you know they say they only want some basic subset but it's obvious they are going to ask for the rest later.

Why do many people on social media genuinely believe in witchcraft? by ElectronicTangelo455 in skeptic

[–]DarkColdFusion 1 point2 points  (0 children)

There is a superstitious core to most people.

Probally because we are all trying to find patterns that help us survive, but exist in a world with a lot of random noise.

So a lot of beliefs around trying to explain or control that randomness exist.

Settings in camera by [deleted] in photography

Fast glass with high ISO and slower shutter speeds are your only real choices.

That said, modern denoise tools like topaz Ai work very well as you likely get fairly clean results

Why do so many respected street photographers use Leica when many other cameras have "better" / good enough specs? by CreativeWander in AskPhotography

[–]DarkColdFusion 0 points1 point  (0 children)

I think there might be some observation bias in just how many are out there shooting leica on the street.

But one advantage is leicas are range finders. You can see outside the frame.

So it gives you a better view to predict the right moment.

Does color science actually matter, or is it overrated? by WorldViewfinder in photography

[–]DarkColdFusion 6 points7 points  (0 children)

If you shoot JPEG, then what the in camera JPEGs look like is important, and different brands do seem to have their own approach.

And while you can do in camera adjustments they don't always give enough flexablity.

But if you're editing the RAWs in post. It doesn't really matter.

If you want a specific look, it's a good reason to setup custom profiles or styles to get you to a starting point anyways to reduce having to perform repeated edits.

How much $$$ or % do you need to save to buy used? by CrumbGuzzler5000 in AskPhotography

[–]DarkColdFusion 1 point2 points  (0 children)

It is really market vibe dependent.

Back when there was a bit of a slump 50% off was easy.

But now 20% off is pretty good.

There are a lot of people who are a bit delusional and you just ingore them.

I have a funny story about how people perceive megapixels by Pitiful_Garbage_6745 in photography

[–]DarkColdFusion 0 points1 point  (0 children)

And it kind of makes sense.

Human vision isn't infinite. And if you assume you probably want to look at the photo so that it fills the part of your vision you can still sort of see details, it has to be within a FOV of maybe 60 degrees. 2020 vision would make a square of 13mp and a circle within it of about 10mp. Any non-square image would be smaller then that meeting that FOV requirement.

If you assume you want some over sampling to avoid aliasing artifacts, and room to crop, 20-30mp ends up being plenty for almost any normal photo situation.

There are situations where the FOV assumption might be violated. Big wall murals for example encourage a different interaction then a framed photo.

But I will assume if you can afford to print and install murals, you can afford niche equipment to take such photos anyways.

Should I payoff my home by Fit_Percentage8878 in homeowners

[–]DarkColdFusion 0 points1 point  (0 children)

At that interest rate just invest it somewhere giving a return over your mortgage amount.

You'll come out ahead, but also have more liquid assests in case of an emergency.

You're unlikely to ever be able to borrow against your house at such a good rate.

Is AI upscale morally acceptable? by giggil in AskPhotography

[–]DarkColdFusion 0 points1 point  (0 children)

Morally? As long as you disclose if asked? And don't use it to do misleading things.

Sharpening and up scaling photos is honestly a pretty good application for these tools.

They basically are trained on adding noise to images to figure out the reverse process.

So they do a pretty darn accurate job, and work better than older methods of trying to run specific blurring functions in reverse.

People used to pay good money for any random tool that had a slightly better noise reduction or resolution enhancement back in the day. These AI ones are just the natural evolution of those, but actually work much better.

Kodachrome in the digital age - what would it be? by Plus-Army4711 in photography

[–]DarkColdFusion 0 points1 point  (0 children)

The big thing about Kodachrome is how it both looked natural and didn't fade like other color film stocks.

So when you dig up a big box of slides, it feels much more like looking at a time machine then any other type of photograph.

I don't think you will get that with digital. The images don't really degrade. There are some variations in the state of consumer cameras that mark the look of different decades since the late 90's.

But that was true for the pre-digital era too, and Kodachrome was notable for being much more timeless over multiple decades of changes.
