New LG G4 - camera issue?

[belodion]

It's good to have you back, 123.

So you're saying that the photo you posted is of unsatisfactory quality? It looks okay to me....though I am only viewing it on a phone.

It looks OK from the link but when I zoom in on the phone picture app- it looks grainy....i guess it means it's normal to be grainy when zooming in!!

It looks like the AC app compressed the image before posting, as it's certainly not a full 16mp resolution. So that's going to create a lot of noise/pixelation on what we're seeing. Probably the most convenient option would be to install the Dropbox app. You'll have to create an account (I'm not aware of any places you wouldn't have to do so), but it's quick and painless. Then you can link here.

As is, the pic looks about like I'd expect, given the compression. It may be a little less sharp than it should, but that could be simply due to a smudge on the lens, which is common. Btw, nice serving ware. We have a similar set too. :sly:

For digital zooming, it is. Like if you zoom close enough in on a printed image in a newspaper, you would see the individual "pixel" ink drops.

So when i zoom in pictures this grainess comes up- i guess i am expecting too much

Yes, that is pretty sad for zoomed in. However, at this point we don't have enough data to place blame.
Any chance you can hook us up with the original image (unedited, not resized) ?

hi,

took two shots of a standard drink bottle.

Many thanks for your help!

Looks normal to me. I think what you're seeing is just standard pixelation at high zoom levels.

Thanks very much. Its very reassuring that I can double check these things online

Looks like the issue is due to the effects of digital zoom.

There is a significant difference in quality between digital and optical zoom. With optical zoom, lenses magnify the image before the picture is taken, resulting in a much higher quality. With digital zoom, the image is "magnified" by cropping it down and zooming in after the image is taken. Its kind of like taking a picture through a magnifying glass of an image that has already been photographed. Any distortion that is there is simply magnified.

Since our phones - and most, if not all camera phones only have digital zoom, zooming in on the image rather than the object will result in image distortion.

However, our phones do have an excellent image sensor and standard lens and are capable of taking exceptionally good pictures. IMHO, auto mode with auto HDR enabled has a tendency to take bad (well, not perfect) pictures. Its good in a pinch when you want to take the phone out of your pocket and snap a picture, however, if you want to take a "reference" shot, or one that you want to publish or keep, our phones have an outstanding manual mode. Its not easy at first but using manual mode with some practice will yield some exceptional photos...on par with some very good DSLR cameras.

I see the same thing when I zoom in on images. It's sharpening, I think. The jpeg compression applies too much sharpening, I believe. Look at the high contrast areas, such as along hard lines and areas between different colors, it's stronger there. Looks like cranking up sharpening in Photoshop or Lightroom.

I wish lg would give us the option to set sharpening levels ourselves. :/

I think I read somewhere that the RAW does shouldn't have any sharpening applied, but that also means doing more editing yourself to make it look its best.
