Photo Quality after exporting

6 years 2 months ago #567524 by thelassic20
I recently got a Olympus EM-D10 my II camera it is my first proper camera. I’ve started taking photos of the stars at night and am really enjoying but I have noticed with majority of them (and most of my other photos) have much worse qualitity once exported to my laptop/photo. For example my photos of the stars have half the number of stars visible the colours are all very neutral and faint and a lot of objects in the image come out somewhat blurry/grainy. This is all compared to what I can see on the camera screen where they is full bright colour clear quality and full visibility. I have tried googling the problem and not that the images will be slightly different being on a bigger screen. I don’t have editing software except the standard stuff offered on the photos app on Mac. Please help me it would be massively appreciated.  I have attached some examples of some of my favourite photos which have come out with much worse quality. Plus any general advice or tips people could add is also welcome.

Despite your description, there's not enough information here.

What format are you using to shoot? JPG, RAW? We also don't know what "standard stuff offered on the photos app on Mac" is, unless you mean iPhoto. (In which case, that's not good enough.) Finally, keep in mind that every image looks better smaller, and the display on the camera is usually bright and sharp compared to reality.

Next, do some research into astrophotography. Your shutter speed is too long, so you're going to get star movement. Also, if you pixel-peep amazing astro photos, you'll often find star movement.

Then you need to learn how to process your images. Those amazing shots you see everywhere? Lots of work goes into those; they don't come out of the camera that way.

So, start here on PT looking for tutorials, shoot RAW, and get some software.
