How too take high resolution pictures?

How to take a picture like this.
but not using an expensive camera, i was thinking more along the lines of a disposable camera or a cheap one?
also are there any editing apps for iPhone or online i could use to make this effect?
please help! I really want good outcomes like this picture!
thank you.

High resolution images require large sensors and high quality lenses. This by default means an expensive camera like a $700 dSLR and you learning how to use it.

A single use camera (you called a disposable camera) use film and a very poor quality, plastic lens

iPhone have tiny sensors and a relatively poor quality lens.

You can buy good used dSLR with lens for under $350, but you will have to learn how to use it.

Here are two samples taken with a ten year old dSLR with a 6 mp sensor.html? Sort=3&o=8.html? Sort=3&o=45

As you can see, the larger sensor and high quality interchangeable lenses are what high resolution images

NOTE: The linked images have been reduced to 600 x 400 mm @ 72 PPI for posting on the website. The original files are fully capable to make prints as large as 16 x 24 inches.

That is not a high resolution picture. I don't think you understand what resolution means.

T1 High Res SLR camera's are good.

You need a film camera, it gives you low cost high resolution

That's 500 pixels wide. That's low resolution.
