refurb'd 7D sensor "test"

ive read where some members have dead pixels or hot pixels (not really knowing what they are speaking of) but i shot a small series of photos with varying shutter speeds (as slow as 25 seconds) and am posting them here. i dont THINK i have any of the aforementioned maladies but maybe someone more enlightened than i can have a look see....

thanks

You have done it right. However, you can't see stuck pixels in a 800x600 image. You do it at full scale 5184x3456.

Of course, you can't post such a photo here, but you should be able to see a lit pixel in a black photo with no need for further advise.

i dont think i have the ability to go that large of resolution on my computer...

maybe ill plug it into the HDTV. and REALLY blow those black boxes up...

thanka

You don't have to display the whole image at once.

Download FastStone. It's a free image viewer with some great features. Use it to display one of your images (double-click on the thumbnail). Click and hold on the image and it will get magnified so that one pixel on the image is one pixel on the screen. You can scroll around the image by using the mouse.

Actually, there's a good chance that your TV is lower resolution than your monitor.

Just view the image at 100% in DPP or Photoshop, and use the loupe tool to move around the image.

Just about any image processing tool has this capability, you just have to figure out the nuances on how to manage this capability.
