My Pictures Get Grainy

Do you look at them at 100% before you upload them to see if they are clear that way?

I wouldn't be posting this if I couldn't tell the difference.

Maybe its just my computer, do they look grainy on here?

I've found that any flaws in my images tend to get magnified by the green box here. (Noise, artifacts, chromatic abberation, etc.) I believe the print quality is equal to what you see on your computer at 100%, but a buyer may not know that there is some "exaggeration" in the full-res preview. Therefore, the better the file that you upload, the less problems you will see in the full-res preview. It's a balancing act. Maybe someday the full res preview will be a real zoom of the file, but for now, it's not.

In the "full size" preview, your images do look very grainy and there is some blur. These previews are not completely true but can be a detriment to anyone wanting to purchase a large print. There will always be some quality loss or compression when uploading JPEGs and unfortunately, FAA does not allow TIFFs, so you will have to double check your images at 100-150% before committing.

Your camera can shoot raw and you should learn how to use that function and be able to edit for noise in the software included with the camera.

I haven't noticed any quality loss when I upload images here, noise or grain as you call it is a common problem when you do night photography, just saying.

Ok

you're welcome.....know you're stressed.

I uploaded a day-time one to and that lost quality

Excuse me for asking...some people don't check that before uploading...including myself when I just started here....

I have also noticed this too, but not because the image is grainy. The image appears blurred at times which I know it is not. This is not using the green box and I only notice this after a new upload, the next day they seem fine.

I've noticed graininess in the pictures posted to Twitter. Assumed it was a resizing thing

if you shoot with high iso - it will get noisy. this site does sharpen images a bit, he fluctuates the amount, but its usually 10-20% i've found. so noise becomes enhanced. always shoot with the lowest cleanest iso you can get away with. also long exposure shots will tend to get noisy as it heats up. further, if you shoot dark and brighten it, it will get noisy as well.

I compared a few of mine at 100% with the FAA versions using the magnifier and there doesn't seem to be any noticeable difference in quality.

1. No.

2. Shoot at highest quality. Shoot RAW. Shoot low !S0. Don't over sharpen which exaggerates grain. Use noise reduction in Lightroom. Long exposures create more grain. Don't underexpose.

Brandon;

What post processing software are you using? Like others have said, this is likely coming from how you shoot and how you edit and then save the image. Save the image as a different file name at the highest settings. Don't "Save For Web" and don't over write files.

I don't even know, I just click upload. But if im going to shoot raw do I need to download anything to process my images.

o,boy

Lol,Ed

you must download the pictures into something? some kind of software the camera came with. that should have a noise repair option in there some place. always edit your images before uploading. things like making it straight is important to selling. if the software you have, has an auto correct - don't use it. it will usually wake up the noise in the shadow. you must be saving this some place before uploading, compression can cause issues as well.

but when you shoot at night like your doing, you have to shoot at a iso100 or you'll have issues. shoot longer than 30sec if you have to.

But my camera the longest I can do is 30, then it says bulb and I dont know what that means.

lol

Sounds like you need a left handed cable release.

bulb means you have to count to make the exposure, while holding down the button or using a bulb.

for now learn to take things during the day. you need a lot of light to shoot at night and its tricky to do. you can show things at half the size and the noise will blend in. with raw, you'll need the software the camera came with or photoshop/lightroom etc to edit it.

in any case, read the instructions.

The Bulb setting keeps the shutter open until you re-click or release the shutter.
Please read your manual and search Youtube for tutorials on your particular camera model; there is so much you can do with it.
If you purchased the camera new in box, it came with software. This software should have raw processing included. Upload that and learn about shooting raw and JPEG. If it did not come with software, go to the Nikon website and search for it-it should be there.

You don't do any post processing, Brandon?

Can someone plz explain post processing. Is that editing your pictures because I do that.

it's editing.

your friend should be helping you here in this dept.

Editing, processing, cooking them up.... different ways of saying the same thing. What software are you using?

Better still......What camera are you using?..................LOL, RICH.xox

Settin' the hook..........

Rich

On most lens if you shoot longer than 30 seconds you will blur stars because of rotation of the earth. Divide focal length into 600 and you get a ball park of how long you can expose before the stars trail on you. 600/25mm will get you 24 seconds.

Ya he helped me with that I just didn't know what processing ment

I'm using a Nikon D5200 and I just use photos from the pc on windows 8 do u recommend anything that is free?

I'm not a Nikon guy, but in the past, my Canon cameras have come with free software. I think one of my first DSLRs came with Adobe Photoshop Elements. If you still have the box your camera came in, look in there. There should be something.

Ok

Yes, my D3200 came out of the box with software. It is not very good, or user-friendly. I would recommend you look into Lightroom or Photoshop. They are not free, but for $10 a month, they are practically free, and the results are incredible.

the results can be incredible, but you have to learn how to use the programs and they have a high learning curve. understanding how to use the camera should come first, and is actually the easy part.

You can try GIMP, which is freeware similar to Photoshop, then find tutorials online on how to use it.

Many editing programs have free trials, most for 30 days. Look into Topaz DeNoise, Clarity and Clean.

Is there any free softwares

Brandon, did you buy your Nikon new, out of the box? It comes with NX free software

New I will check when I get home

High ISO and oversharpening are the two most common causes of grainy/noisy images. Do you have the EXIF data for the images you uploaded? What ISO were they shot at?

The one that is your profile pic I'm guessing was shot at a high ISO to get that many stars in a 30 second exposure. That is common in astrophotography as anything with a foreground is limited to 30 second exposures or less to get stars without trails, so it has to be shot at high ISO. If you want to get rid of the noise in a shot like that the quickest options would either be to upgrade your camera to one that handles high ISO better or to try and remove the noise in post.

You might take a look a PhotoPlus by Serif I use v5

http://www.serif.com/photoplus/

Brandon;

Open a Flickr account and load these shots there. That will let us see the EXIF data and help you better.

Why is this still going exactly?

I shot at 100 iso

then something is going on when you edit. or the cmos is too hot. it shouldn't be that noisy for many of these.



like this one has noise near the trees. it might be from increasing brightness, but i'm thinking the cmos is overheated, though typically you get bands from that. so its hard to know what it is.

try shooting in raw next time, the clean up in many raw converters often does a very good job removing the noise. plus you won't have the compression issues jpg's have from camera. like my raw is sharp, but my jpgs are blurry.

It doesn't look like that before I upload it

Brandon-what size and resolution are you saving them as before you upload? Did you try to resize them at all to make them larger, then upload?

it has too. be sure your looking at it at 100% and make sure your screen is calibrated. the color space your editing program is using may be different than the online one and this site brightens the image a touch, about 10% i figure. if your screen is set too dark or its not calibrated or the color space differs, you may not see what we are seeing here.

Idk what resolution

When you open an image in whatever program you're opening it in, there should be an "i" in the selections-that gives you your info on the image, including resolution.

maybe you can ask this guy what he does with his images, they look like yours quite a bit, a few of them anyway. your friend? the guy in the picture is you, it has your name there. my guess is, he could help you out with that exif / iso issue.

http://ink361.com/app/users/ig-48598328/brandon_nikolajevic/photos/ig-864766813793420453_48598328
you have your own version here as well, ideally i would ask him what the settings are, it should open up any mysteries we are having here. because i don't think these are iso100.

EDIT

just as an edit, i didn't post this to start trouble, but what i'm thinking is, he got a camera at christmas, 10 weeks ago. his friend set up the shot, settings etc, and posed for the shot. the friend is into astro-photography. he posed for his friend and vice versa. he took the shot, but didn't set up the camera and being new doesn't know how the camera works or the settings etc.

this image confused everyone because it's on a skill level of a higher plane, especially with the beginner questions. i think their two shots were taken at a clean iso. while the new ones are taken at a much higher iso, using a lot less light. so the difference is much more glaring.

I am going to shut this down while we sort some stuff out behind the scenes.
