That is exactly what I am experiencing! I guess I didn't notice it was purple since I am legally colorblind =). So would it be safe to say this is normal? I will definitely keep na eye out for the application from DPreview. Thanks again!

Again I don't know why when I upload the image the noise looks like JPEG artifacts instead of grain...but it does.

Okay here is an example shot with the lens cap on Shot in RAW. Same thing. Lots of graininess on the top and bottom of the frame but not as much in the middle (relatively speaking). The image is at ISO 3200 and I added +1.09 exposure comp before converting it to a JPEG in order to accentuate the effect I am seeing. Has anyone else experienced this with their K20D? I am sorry if I sound ignorant I have just never seen this before =(. I just want to make sure I do not have a defective sensor. Thanks again!

Hi Ash,
Thank you for the warm welcome and the comment. Just to clarify I took the picture with the lens cap on. I can see what you mean by the presence of jpeg artifacts. I actually took the picture as a jpeg and it looked like noise (distinct grains) until I resized it for the post at which point it looked blocky like a jpeg artifact. I imagine it is because I resized it that the artifacts emerged. I will take a couple of raw shots and resize then convert them to see if I develop the same results. I will keep you updated!

Hello all,
So I just received my first Pentax =)! It's a K20D with an 18-55WR. I have just been doing some tests with it just to make sure I got a good sample and I noticed an interesting noise pattern. Whenever noise appears it tends to appear heavily at the top and bottom more so than the middle of the frame. I am including a dark frame at a high iso (3200) to show you what I am talking about. Please understand I am just trying to ensure that there is nothing wrong with this camera so I don't have to send it back. I am coming from Nikon and I know that all camera manufacturers have different noise patterns. I just want to know if this is normal. Any advice would be greatly appreciated. Thanks much!

Hi everyone,
I am a Pentax newbie. I started off with Nikon film gear and when I switched to digital I went with a D90. I have since sold off my Nikon digital gear (kept my film gear for sentimental reasons) and have switched to Pentax for Digital. I am still in school, money is tight, and Pentax seems to be a great system for photographers on a budget. This was not the only reason I switched. I worked part time in a camera store that sold Pentax. Though there was very little there I really liked what I used. Every day I played with the lonesome K20D and 18-55 until one day I decided to buy them. Though the K20D may lack in some areas compared to the D90 it more than makes up for it in features, ergonomics, and robustness. I have not regretted my choice one bit! My sister has asked that I photograph her wedding in a year and I have made it my goal this year to build myself a small system (on a tight budget of course) and improve upon my skills as a photographer so that I may provide her and my soon to be brother in law with the best photographic memories I can. This site is a blessing for Pentax newbies like me and I want to thank all who may help me in adavance and offer my advice, experiences, and photographs to all those who inhabit this site. Thank you again and hellooo!!!!!
