Sorry but you can't do this. If you've already taken a photo and the resolution is lower than 5MP, there is no way to increase the resolution later, only to decrease it.

Before I get lots of arguments I will say that technically it is possible to create a larger file from a smaller one, but the larger one will still have no more detail in it than the original, and would completely defeat the point of their rule.

They have the rule in place because they want photos of a certain quality standard. If your photo is lower than that standard there is no magic way to make it better.

I cannot think of any modern camera with less than 5 Mpixels, so the solution is to get yourself any reasonably modern camera. I would expect that every digital camera listed here has more than 5 Mpixels.

The process is easy but pointless (see below).

how to do this?

In Photoshop you open the file, go to the Image menu and select Image size .... Type in the number of pixels wide and high you need to get above 5MP. Click OK.



However, that increases the number of pixels but not the quality of the picture. This is the upsized version (look at original size)



and compare it to the original, smaller file. As presented here they look the same but at original size all the upsized version has done is exaggerate the low level of detail in the picture.

Even though over 5MP this picture wouldn't satisfy "Unsplash Photo standards. We don’t accept unclear photos …" So, as I said, the exercise is pointless.

Interpolating an image up technically doesn't increase resolution, but in practical terms can make small details visible to the eye.

Absolutely, you are correct that a larger image is better than an interpolated image, but interpolating is often better than nothing...

People new to photography often mix up megapixels (the number of colored dots that make up an image) and megabytes (how much room it takes up on the hard drive).

Here's a 5 megapixel JPEG image (2500x2000 pixels), it takes up about 2 megabytes of space on my hard drive:




It's raining in Southern California! This is both good and bad news.

Make sure the image you are trying to post is not a "preview" of your original image, or a resized-for-sharing copy; check the settings to ensure your device is exporting the full image.

Gerry,

It would probably be cheaper for him to buy a "greater than 5MP " camera than Photoshop, if he hasn't got it already.

Possibly, although at £10/month it might take a few years for the cost of PS to exceed the cost of a decent camera.

But I answered his question, which was about image size and not about choice of camera.

What camera are you using?

The reason I ask -- I once came across someone shooting with Canon IXUS. Only she had figured out that she can get much more photos on a SD card if she shoots 640x480 resolution, while the photos (on camera displays) look exactly the same.
