Prints have darker same color circles are the same size.
Prints have darker same color circles and are the same size in the same place using to different lenses. I cleaned as per d80 manuals instruction and number of circles increased by a few. I shot a photo of just blue sky and can really see 6 circles all the same size in the same placed using 2 different lenses. The paterns are uniform.

Re: Prints have darker same color circles are the same...
The ccd sensor is dirty. Have it cleaned at a camera shop. You can do yourself with sensor swabs and eclipse fluid but it a is very delicate operation. Local shop here cleaning is $45 and no spots, well worth it.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

It is mostly due to changing the exposure compensation. You can change it from +2 ....0 ....... -2. +2 Makes it Brighter while -2 makes it darker... On the back of the camera you will see an OK button surrounded by a disk that on the right side shows [+/-]. You use this to change exposure compensation. When you get the camera READY to take a photo you can use that [+/-] button. When you push it you can adjust it to zero (o) normal or to make it lighter or darker.
Digital Camera Basics - A primer
Digital cameras are confusing to a lot of new users. In this basic guide to digital camera technology we hope to try to give digital beginners at least some basis to use in deciding which digital camera is appropriate for them. When shopping for a digital camera it's at least good to know what the basic terms like white balance, pixel, ppi and dpi mean and how they affect image and print quality. It's also important to know the difference between things like optical zoom and digital zoom as well as the advantages and disadvantages between storage formats such as Compact Flash (CF), Microdrives, Sony Memory Stick, Secure Digital (SD), Multimedia and camera interface technologies such as USB 1.1, USB 2.0 and Firewire IEEE 1394.
A pixel is a contraction if the term PIcture ELement. Digital images are made up of small squares, just like a tile mosaic on your kitchen or bathroom wall. Though a digital photograph looks smooth and continuous just like a regular photograph, it's actually composed of millions of tiny squares as shown below.
Each pixel in the image has a numerical value of between 0 and 255 and is made up of three color channels. So for example a pixel could be 37-red, 76-green and 125-blue and it would then look like this . If it was 162-red, 27-green and 12-blue, it would look like this . There are over 16 million possible combinations using this scheme and each one represents a different color. Computer savvy readers will note that each color in this scheme can be represented by an 8-bit number (byte), so the color of each pixel is defined by three color bytes. This scheme can be expanded, for example to use 16-bits (two 8-bit bytes) for each color. images using three 8-bit values are sometimes called 24-bit color images. images using three 12-bit values for color definition are called 36-bit color images, and those using three 16-bit values are called 48-bit color images.
One of the main ways that manufacturers categorize their digital cameras is in terms of pixel count. What this is is the number of individual pixels that go into making each image. Today this number varies between 1 million (1 Megapixel) to around 14 million (14 Megapixels). A million pixels is abbreviated to MP, so a 1MP camera has 1 million pixels and a 3MP camera has 3 million pixels. Currently most popular consumer digital cameras have between 2MP and 5MP. A 3MP camera can make excellent 4"x6" prints and very good 5"x7" prints. If you intend to make lots of 8"x10" prints, then perhaps a 4MP or 5MP camera would be a better choice. Sometimes two numbers are given, total pixels and effective pixels. Total pixels count every pixel on the sensor surface. Usually the very edge pixels aren't used in the final image. Effective pixels are the number of pixels actually used in the image after the edge pixels have been dropped.
The aspect ratio of a camera is the ratio of the length of the sides of the images. For example, a traditional 35mm film frame is approximately 36mm wide and 24mm HIGH. This has an aspect ratio of 36:24, which can equally well be expressed as 3:2. Some digicams use the same aspect ratio for their digital images. For example most digital SLR (single lens reflex) cameras have a 3:2 aspect ratio. However, video monitors typically use a 4:3 aspect ratio. For example a monitor with a 800x600 display has a 4:3 aspect ratio. With this in mind, most consumer level digicams use a 4:3 aspect ratio for their images.
The size of the digital sensor element (which is equivalent to the size of the negative for film cameras) is pretty small in all consumer digicams - typically around the size of a fingernail (and a small fingernail at that!). As I said above, a 35mm film frame is 24mm high by 36mm wide but most digital cameras use sensors very much smaller than this. Here are some typical digicam sensor sizes. The "name" of the sensor is based on specification for old TV tubes used in the 1950s. Nobody is quite sure why it's being used for modern digital sensors since the "sizes" don't really relate in any consistent way to the actual physical size of the sensor. However these names are widely used, so it's best to know what they are. They are often listed in digital camera spec sheets.
The Kodak Star 435 uses standard 35mm film, also known as size 135. 35mm film is available in a variety of lengths: 12-, 20-, 24, and 36-exposure.
You can get 35mm film for black-and-white prints, color prints, and color slides at any decent camera store. Many supermarkets and drugstores also carry 35mm film, though not as wide a selection. And, of course, you can buy film online.

using the RAW setting will give a higher quality photo, the other formats compress to jpeg causing you to loose some of the original photo information. the ZoomBrowser EX program allows you to edit the RAW image, I recommend getting the large prints done at Kinkos or some place like that. I've gotten poster size prints done that look very clear. Use a tripod to combat camera shake, it is very apperent at that size of print. Also a low ISO to help reduce noise.
As dpi is generally a printing specification, the size you set on your camera depends on what size prints you want to make. If you want to print 4" x 6" prints at 300 dpi, you can set the size to M2. If you want to print 5" x 7" prints at 300 dpi, set the size to M1. Anything larger, set the size to L. With L selected, an 8" x 10" will still be about 300 dpi, but any larger print will be at less than 300 dpi.
I'm guessing, cause i own a F505 and not a FD73......but, I dont even see a use for the F505 "standard" quality setting. It will stay on "FINE" quality always.
I've got a HP 882c and it prints just fine. I use HP premium photo paper and the printer setting BEST. Are you using photo paper? Regular paper will bleed the colors around.
Take some pictures on FINE and print them out on photo paper w/ printer BEST and compare.
The higher quality will not degrade the prints, you can always reduce the size for printing, if you wish. (Although it shouldn't matter, if the printer is not able to print all the pixels due to limited resolution, it will downsize properly, anyway).
The only drawbacks are, as you noted, increased size/storage requirements.
I would shot always in the biggest possible size and with fine JPEG (no sense in using TIFF - the quality is not so different that you ever notive it).
The reason for always using the biggest size is that you can later crop and have better chances at postprocessing. When "THE" shot comes your way, you don't want to accidentily store it in all the glory of 800x600 pixels :)
(Switching sizes is a bad idea, you inevitable forget to switch the size back and shot an entire afternoon in the small size. Been there, done that, did not get the pixels back :)
