Hello everybody!

I have a question and I'm sure you guys and girls can help me.

I'm shot some objects and animals by long distance and I need to crop the image to get the results that I want.
So, since I'll crop the image anyway, where should I do to loss less quality as possible? At the camera or at the computer? Or doesn't matter?

I have a Nikon D3400 with 18-55 and 70-300 (both lenses are the cheap version)

Thank you all
Armando

I do not know this for a fact, but my answer would be that if you crop within the camera, you still get the megapixels that the sensor writes to the card. In other words I don't think the camera crop involves pixels being removed from the image.

However, with cropping in Post Processing you are throwing out the pixels that are cropped from the image. ?????

Any one else on this?

Test this by doing a crop in camera. Then do reg pic from the camera and crop to same as in camera crop. What is the file size of both files. I suspect the one cropped in Post (not in camera) will yield a smaller file, hence not print as big.

My one camera saves the in camera cropped version as an additional image.
In either case (camera or editor) you are loosing the pixels from the cropped image. But isn't that what you wanted to do?
Editor crops are usually more precise, where camera crops are in predetermined steps (zoom increments).
I always save the original image in case I decide to crop differently at another time.

You can do the same thing in post!
Whether or not the camera give you the same number of pixels or fewer you can do that in post!

When I crop in the camera it makes an additional image too.
I'll do both and see the results.

better in the computer. Even with the simplest crop where say you crop say 50 pixels off the width do you take from the left, the right, both ? This choice will move your subject in the frame. Every option is open to you on the computer not so on the camera. Even a simple thing like a tilted horizon would be harder to fix without cropping away more, if you cropped in camera.

Good to know, thanks.

I hate to state the obvious, why not get closer? I have the D3400 as well. The problem with the 70-300 kit lens that I experience, is that it is not VR and almost impossible to hand hold at the 300, which has an angle of view even higher, so really requires a tripod.

Because sometimes is not possible.

I do have a tripod and I use it. But the tripod doesn't put it me close to the object.

No matter where you crop, you are destroying pixels - the cropped image loses a part of the background.
That misses the point though. To retain information by creating a photo that has little beyond the portion of the image you want, you need a longer lens.
I greatly prefer leaving the image alone in the camera, and wait until I have it on a large screen, where I can do a better job of judging what should be retained, and what should be removed.

I crop everything with Lightroom/Photoshop. Your camera (the Nikon D3400) has enough resolution for you to get shots, (especially with the 70-300) and crop at least 20-30 percent off the image.. and probably more depending on your shot. I also have the old version of the Nikkor 70-300 lens and I get decent to good long shots. I have replaced it with the Nikkor 80-400mm lens but the wife still uses the 70-300 as it is considerably lighter and easier to carry. I also use an 18-70mm lens for the other end. Both are kit lenses but usable. My cameras are a Nikon D7000, D7100 and D610.... your D3400 should work fine as far as resolution goes.. It has as good or better than most of my DX cameras. The only real issue for you is that your camera NEEDS the lenses with the SWM (silent wave motor) in order to auto focus.. otherwise you have to manually focus.
