Artifacts on D-LUX 4 images

Hi,

 

I'm mostly a lurker in this forum, but I now have what I consider a serious issue with some of my images. I recently was at an outdoor antique-boat show where there were a large number of gorgeous boats on the water. Most of these boats had a great number of parallel lines because of pinstriping, lapstraking, chrome gunnels and such.

 

Many of my images of these boats have what I believe is called stepping, with any narrow parallel lines that are running diagonally across the image looking horribly jagged. Especially troubling is bright chrome that is catching specular reflections from the sun. The effect is worse when images are displayed below 100% but are still visible at actual size. And of course, it's equally visible in both RWL and JPEG. I've had this camera for about a year now, and have never noticed this before. But now going back over other images, I can see it in any photo with similar narrow diagonal lines. Just much more obvious in these boat images because there are so MANY lines.

 

Now, I'm heard that stepping is a product of a small sensor, but is there anything I can do to reduce its effects? Do all D-LUX 4s suffer this, or is it peculiar to my particular sample?

 

My email address is odyssey@stny.rr.com if anyone would like to see the images in question. Thanks for any insights and advice.

Could you please post some examples?

You have shot at small jpg to cause this, or are trying to work on thumbnails. It has nothing to do with the sensor size. One thing: cheap monitors tend to do this as well. If you enlarge the image, the jaggies suddenly disappear in that case.Look at the image size. You should be in the thousands for the width.

Do you see the effect on a print, or only on a screen?

I suppose I could post them on Flickr and include the URL here, but now I don't think it matters anymore. See below.

Actually, I always shoot at RWL and high quality jpeg at the same time, 9meg size and in 16/9 format. But see below.....

Since switching to digital, I only occasionally print images at the local drugstore for friends, prefering to view them on my MacBook Pro, or iMac, or TV. But see below........

I want to thank you gentlemen for the attempts to help this poor idiot. But let me tell you that something rather bizarre has occurred. When I went to view them again just now, the images NO LONGER DISPLAY the horrible jaggies that discouraged me so much yesterday. I've tried everything, from both the RWLs and JPEGS in C1 and other imaging programs but can't reproduce it. I'm at a total loss, but am wondering if there is some software glitch or some interaction with another program that I may have inadvertently had open at the time. Believe me, I feel rather foolish today, but am still perplexed. I'll see if I may be able to reproduce the effect again, and if so, I'll be getting back with you...........<sigh>

 

Thanks Again.

It's a benefit of the forum...make a post...problem resolved.
