Spotted a fox today on my lunchtime walk and took a couple of shots before he spotted me - I should have lay down doh!!!

Anyway the photos are really grainy and I am assuming this is due to the ISO being 1600 - yeah?

I nust have had it on Auto ISO. I did have it on a monopod.

Here is the FULL RES photo (JPG)

If anyone thinks they can get rid of this noise I would appreciate your efforts.

Thanks

I think it's a combination of high-iso and underexposure noises. I can denoise it successfully in NIK, more or less, but at a huge sacrifice in acuity. I'd be more inclined, if it were mine, to crop and then ADD noise for an atmospheric effect :-)

I like kidding about Canon, but believe me, I couldn't shoot with the system now. If you underexpose it's a nightmare. I'm much more impressed with the lack of details than with the noise. Great lenses, great bodies but sensors are not as good as other cameras bodies.

That's what I have done, I think you can surely improve it a lot:

Thank you Robert. I wasn't aware of "underexposure noises". So when you denoise it - you lose a lot of detail - is that what you mean?

Thanks:)

Hmm perhaps you do have a point after all - I wish I had taken the same shot on Nikon with the same settings to compare:)

Eveything has been done using camera raw, so I can send you the XMP file :)

You can send me your e-mail address with a PM and I'll send it back to you!

I'm often in Scotland, I could steer southwards and visit you, so you can explain me how you are able to keep the cows still when you are taking photos :D

The cows are easy - it is the sheep that are difficult to keep still. Tried to photograph some today when I met the fox and they disappeared as soon as I climbed over the gate. Bah..

You should visit northern Shetlands, so many of them, especially in Hermaness. I shot videos of some lambs playing - too funny. This is a camera grab:

There is nowhere on Earth I would rather visit than the islands of Scotland. I just need to persuade the rest of my family that it would be a great holiday - sitting in a field taking photos of cows and sheep is not their idea of fun unfortunately

Well, you can start with a weekend Skye, if you like. Just you. I'm sure I know a guy on that island who can offer you a place to stay for a day or 2-3 and even can show you some of the beautiful places over there ;-)

Yes, and it still is. We have a spare twin room, so you even can come together and share that room.

@Kees - Skye is top of my list of destinations to visit in Scotland. That is a mighty fine and kind offer - there is nothing I would love more than spend some time with a local taking photos of this most stunningly beautiful part of the world.

Looks like there is miss-focused as well. The leaves in the branches on top are clearer. If it's the end of the focus length that is a trade of this lens. The 5.6 there is not great at all... at an F8 you might have had better results.

I tried to work on it a bit in LR and a bit of PS. The noise does not bother me as he lack of details.

Here is my try... did not reduce the noise but rather make it look sharpener. I did not touch in any way the colors or the WB. Better seen at full size (its 1600px)

Thank you Tiberius. I am starting to think there is an issue with this lens. The camera has just had a service at the Canon Repair Center so I am ruling the camera out. I was on my lunchtime walk today and in my village found 7 deer - not something I see every day in my village. Anyway I thought I was in for a treat and hoping for some great photos. I took over 800 photos and not one of them I am pleased with:(

I got quite close to them but all the shots are lacking in detail.

Here is an example shot which was taken at ISO 200 on a Monopod. Note I have a B+W UV-Haze Filter on this lens (for protection only) - I have just read there may be issues using filters with this lens but not sure whether this is just rumour.

Focal length 400mm

I use a single point Auto Focus - so hopefully I have not missed the focus on over 800 shots.

Perhaps it was just not great light or my settings were not optimal but I was hoping to get better results.

Could the lens need calibration?

However I was happy with this shot taken with the same lens about a month ago

Focal Length 248mm

Perhaps as you say this lens is not great at the end of its focus length. I would like to get to the bottom of it as feel I missed a great opportunity today.

5.6 is soft... End of the zoom is also soft...

Unfortunately I have removed the photos from this thread . ' . substr('//www.dpchallenge.com/images/user_icon/21.gif', strrpos('//www.dpchallenge.com/images/user_icon/21.gif', '/') + 1) . ' Cory also mentioned "If you are going to shoot wide open, expect softish images. They'll usually sharpen well. I still like to stay faster that 1/x for shutter speed, even with the IS."

It's a great lens and it takes a while to get used with it. I am happy to have it

What Bear said... and mostly the underexposure. Your Canon 6D is more than capable of producing a clean image at ISO1600, but if you have to drag the image out of the low end of an underexposed original it's going to bring lots of noise with it. That said, your skittish visitor probably wasn't going to sit still for a long exposure and sometimes it's better to live with a noisy image you captured than a blurry one you missed. This was all I could manage with your original:

Thank you Shannon. I hope it is just a case of underexposure. I can understand the fox photos but 800 deer photos on a Monopod with good light (I thought) and ISO values less than 500.

I realised my cheeky monkey photo was taken on the Canon 100-400 Mark II that I had hired prior to buying the used Mark I.

Anyway I will do some test shots on a tripod to try and figure out if there are any issues.
