What's a good camera? Well, the answer completely 100% depends upon what you shoot and your personal style. For example, if you're a landscape shooter, then the best would be one with a large sensor such as full frame (i.e. 35mm format) or medium format such as the Pentax 645Z or the Fufjifilm GFX. These cameras provide higher resolutions than cameras that use smaller sensors. Furthermore, because of the larger sensor size, the pixels themselves can be larger. On smaller formats, having more pixels means having to use smaller pixels. So what's the problem with that? Smaller the pixel, the lower the dynamic range, the more noise you'll get and the sooner you'll experience diffraction which robs you of sharpness. For this reason specifically, landscape shooter, or anyone who typically shoots at low ISOs will want to shoot with a camera with a large sensor. Additionally, having higher resolution will allow for larger prints which is common for landscape photographers.

The problem is that these cameras are notorious for not having very fast focusing systems suitable for sports nor do they typically have large internal buffers which allow for shooting at fast frame rates. For this reason, they aren't good for sports and wildlife shooters. For them, cameras like the Canon 7D Mark II or the Nikon D850 will be a better option.

If you need very good high ISO performance, then having a lot of pixel is the last thing you'd want because of the poor ISO performance that comes with having a lot of, and therefore smaller, pixels. For those photographers, the Sony A7S II with 12MP is the best camera out there.

So which camera is best for you will depend upon what you shoot and your needed work flow because cameras like the Pentax 645Z are cameras that force you to work at a much slower pace.

2) People have trees in their homes? Really? Okay, say that you find someone that does. You would photograph it just like anything else. You could use ambient light or you could set up artificial lights such as an on-camera flash or one or more strobes on light stands. How you set up and place those lights is the hard part and will change depending upon the look that you're after.

3) Cameras in cell phones cost anywhere from $5 to $20. Even the $1,000 iPhone X uses a camera that can be purchased on eBay for around $20. These camera modules use the smallest sensor available in any kind of camera. As a result they have the lowest image quality because of the very small pixels and the low-quality plastic lenses that they have, too. So there really isn't a "good" camera in any smartphone. But, depending upon your needs, there are likely to be a camera that is good enough. If, for example, you like to make prints at 8x10 or larger, then there isn't a good smartphone camera. But if all you do is post to social media, then there are a lot of cameras that are good enough. Reason being is that when you view images on a small device such as a tablet or a smartphone, the resolution and the image size is far too small/low for the human eye to detect all of the defects created by the small sensors, small pixels and cheap lenses.

Another problem with smartphones is that they almost always have wide-angle 28mm (35mm format equivalent) lenses which limit you to what you can do. Wide-angle lenses are not designed to produce good quality portraits because of how they distort the perspective. You can see how they make people look ugly because of their distortion in this link: Again, for reference, smartphones use lenses that are equivalent to 28mm lens.

Because you're stuck with a single wide-angle lens, you can't zoom in. You can't take candids. You can't take shots of anything far away. The wide lens is designed for landscapes, architecture, interior shots and group shots. Anything else and the lens is just not a good, or more often, a really bad choice. For this reason, you should consider getting at least a point-and-shoot with a zoom lens.

Here's a link to a site that allows you to compare image quality among various smartphones:

3) For the most part, when using a smartphone for photography, you really do not have any control over the settings. Yes, some cameras do have "some" control, but nothing like the control that you have with a mirrorless or DSLR camera. So how do you take great shots if you can't control the camera? Well, consider that 80-90% of what goes into making a great shot has nothing to do with the camera or lens. It's all about the decisions made by the person taking the photo. Your decision as to what to photograph, what light to photograph under, when to take the shot (i.e. Timing) and your composition are completely non-camera specific things. Anyone with a solid understand of light (knowing the difference between good and bad light) and composition can make a great photograph regardless if they're using a smartphone or a $5,000 DSLR. Knowing this fact, if you learn about composition and the various qualities of light, you can incorporate that knowledge in your photos even if you only use a smartphone.

There are tons of books like Brian Peterson's "Understand Exposure" and Tony Northrup's "Stunning Digital Photography" that will teach you the fundamentals of photograph and all of those important decisions that are needed in order to make great photographs, as opposed to "taking" snapshots.

5) Having a loose part does not necessarily mean that there's something missing. It does mean that something has either come undone or loose, or that something has broken. In the case of a Canon Super Quick, the camera is not repairable, so just toss it and get a new camera - preferably one of a better quality.

6) Reconditioned, refurbished or even used camera gear is a great way of getting more value for your money. In many cases, you can actually buy a better used camera than what you'd be able to get if the camera was brand new. Buying from a retailer like keh.com is a great way to go since Keh offers a 6-month warranty on everything that they sell. Buying used from a private seller comes with more risk of getting scammed (getting a broken camera or just a box of rocks), but that's the risk you take for getting an even better deal on a used piece of equipment. All but one of my lenses (purchased off eBay) of my lenses were purchased used from Keh.com. And with only one exception, all were received in perfect physical and cosmetic condition. The exception was a 200mm lens that had an AF problem that was fixed for free since it was under warranty by keh.com.

7) What do you mean by "grow" the image? Can you provide a link to an example?

8) When you say "application" I assume you mean app or software for image editing. By far, Adobe Photoshop and/or Lightroom CC, which are sold on a subscription basis for $9.99 per month, are the most used and among the best apps for image editing. They also have the most free on line support of any app by a large margin. Other image editors are Lumere, OnOne, Capture One, Gimp (free at gimp.org), darktable (free at darktable.org). Gimp is among the best free options since it's a solid app that has a lot of support on YouTube and other sites for when you need help in knowing how to use it.

1. One you can afford that you know how to use.
2. Ask permission first. Yes.
3. None.
4. Ask around.
5. If that button is the shutter release then yes.
6. No.
7. A dissecting microscope. (Edit: With a monocular eyepiece)
8. One that's really useful to you.

One that creates the images you wish to produce at a cost that you can afford.

Answer to # 7:

Get a USB microscope camera.

There are some that don't do the job well at all,
but there are a few that are really good.
The good ones don't cost much, if any, more than the bad ones.
You will have to sort that out yourself,
and/or find reviews by actual users of the various models.

Unfortunately, since I have no personal experience with any of them,
I can't make a specific recommendation.

At some point in the future I may buy one myself.

This is the best camera https://amzn.to/...to/2WruLmV
