I recently bought the Panasonic FZ5 and on the whole it is really a pretty good camera. However I find that compression artefacts can be a problem, especially in areas of a plain colour. As a lot of my photos are shot for stock, it is quite important to get rid of this and I am finding it quite an effort.
I am using Photoshop Elements 1 at the moment, but I see that Elements 3 has a healing brush and am wondering whether this will help me here. Is it worth my while upgrading for this feature? Also, what other features might I benefit from?

The healing brush is similar to the clone tool except that it givs more consideration to where the brush is working rather than where it samples from. It more or less clones similar pixles from the working area around the brush rather than the the sample point.
"The Healing Brush tool lets you correct imperfections, causing them to disappear into the surrounding image. Like the cloning tools, you use the Healing Brush tool to paint with sampled pixels from an image or pattern. However, the Healing Brush tool also matches the texture, lighting, transparency, and shading of the sampled pixels to the source pixels. As a result, the repaired pixels blend seamlessly into the rest of the image."

| I have a Pansonic FZ10, and although I took excellent photos for DPC, I have to NeatImage the hell out of them to get rid of noise levels for prints. Are you sure that you're not actually looking at noise rather than compression? Compression shouldn't be a problem if you're using a high quality setting. I wouldn't recommend a Pansonic FZ camera for stock photography for this reason. |

| Make sure on you settings menu in the camera you have the 'noise reduction' set to standard or low, not high. When I had my FZ20 there was a menu that let you set the color, contrast, saturation, and noise reduction to low, standard, or high. It is best to set the noise reduction to low or standard. |

This is off-topic, but related:
To confirm, Am I correct that the healing brush is not allowed for basic challenges? |

Compression artifacts, which are mostly related to .jpg compression, may be caused more by your post processing techniques than by your camera. To test this theory look at your untouched image and compare it to your post processed image. If the artifacts are not in the original then they were generated during post.
Artifacts may not even show when printed, but will affect your ability to sell them online as stock images since they will be visible to prospective customers in the online image.
I suspect that the artifacts are a result of post processing. Once you have artifacts they are difficult or impossible to get rid of. I know, I've tried. I usually get them if I post process sky separate from the rest of the image. There are ways to get around that that I use. One is to create mask selections for the colors I want to modify and use color painting to enhance them rather than other adjustment layers applied to regions of the image.

Maybe it is noise - I only know what iStock calls it. I've had the same problem with my Canon A80. The fact is I've mananged to fix some of the pictures using a combination of Neatimage and Photoshop Elements 1. I just want to know whether the healing brush will make it easier. It sounds like it might.
