I'd like to have some opinion about the artefacts on DSC_033. What is it called and how to avoid it?

Gerard, I can't see the artifacts, but then again I am seriously in need of new glasses.

However, I reckon a crop just above the line of the flowers at the back of the field could make for a more dramatic composition.

Overall, you have some good shots there, nothing ordinary about them at all. I particularly like 15r.

Looking forward to seeing some more.

Like Greg I can’t see any artefacts - a very nice set of pics - it may seem strange but the one that took my eye was 33r

Chris

Thank you for the replies, I do appreciate. The artefacts are on 33r, in the fog one can see a halo type of rings. This seems to happen when there is too much sky...

Funny, I looked at 33r in case that was the one you meant, but I couldn't see any artifacts on that one either! My eyes are well stuffed.

Glamy - took the photo into PS and could still not see any halo effects but I did see that you have some sensor gunk towards the top left hand side. Maybe if you give the sensor a clean the halos may disappear!!!

Chris

Gerard, I could'nt see any artifacts either. You have some good shots there. My fav is 060.

I too can't see any haloing on 33r, however it is usually caused by the JPEG compression. If it becomers a problem, just back off the compression a bit when you convert them. There is a noticable 'dust bunny' in the top left area. Time to clean your CCD

They are all nice pics, with thoughtful composition.

One thing i might add is that i think you would be better off loading and using a custom curve for landscapes, such as the Digital_Fuji or Digital_Agfa which tend to get a bit more colour and contrast out of long distance shots. I use the Digital_Agfa and i find it not only brings out more 'oomph' from the image but also increases colour saturation especially with greens and blues. This would be very effective with your snow shots, brining out the blue sky more, such as a polariser can do. If it's used in conjunction with a polariser, it can be even more effective.

There is a plethora of curves available in the 'important links' section of the forum along with info on how to use them.

You obviously ran it through Photoshop... perhaps you're confusing artifacts for the way jpeg's look after they go thru Photoshop's web conversion algorithms?

I am really pleased with your interest and comments. I posted another picture called artefacts. What you can see in the sky is what I can see in the NEF file as well. This is the "In Box". This is present to a lesser extent in 33r and as you can see may get very annoying.

Steve,
I am not using Nikon Capture which I think is required to download custom curves on the D70. This was my first outing with the 12-24 Sigma and agree this could look better but am not keen on donloading stuff into the D70.

G'day Glamy,
I'm struggling to see the artefacts or halos, but I really enjoyed the pics... I like your style and compositions... 0060 and 0082 are my favorites... Very nice...

Cheers,
Mudder

It may be more obvious on that shot...

I see nothing ordinary about those photos, maybe a little leveling and perhaps some colour saturation on some. For some reason DSC_0014 appeals to me, perhaps crop out some of the excess sky but I really like it.

Cheers

Hi there

I can see the halos that you refer to,and like nnnnsic, I think they are probably from compression - either at your end, or at PBase.
Sometimes you see halos like this from oversharpening, too.

Nice pix though.

That's correct Gerard... at the minute you do need Capture to load a curve... let me tell you that it is quite straight forward and plenty of assistance to be had here if and when required.

At this point though you're probably better off leaving them for another day... you can get plenty from the D70 without embedding curves and can do all the adjustments you might desire in PS.
