The differences in optics




The top photo was taken out of a window with a Canon A70 Powershot. It was shot at 180 dpi with 2048x1536 pixels and was originally 1.08MB. I took it into Photoshop, cropped it and straightened the tower, and then "sharpened" the steeple. I always change the dpi to 72 because I work pretty much exclusively on the web. The final photo is 377x260 and a mere 108KB.

The third shot down was taken with my Nikon D40. Of course I got a much better photo because I was able to change the F-stop and focus on what I wanted. The original is at 300dpi and is 2000x3008 pixels. I brought it into Photoshop and straightened the tower, cropped it a bit and played with the color saturation. Then I saved it at 72dpi and the final shot is 533x711 and a mere 137KB.

You can definitely see really lost no detail in the photo taken with the SLR. The amount of things I did to the Canon shot really affected its quality and you can actually see the pixels in it!

Were both the original photos taken through a window? You really brought out the color of the tree in your last photo by adjusting the saturation.

Really nice perspectives! I wish I knew half as much about my camera as you seem to know about yours, Thanks for the inspiration!

Yes through a window. I'm renting a house with skylights in this little half story on the 2nd floor and they intrigue me. But obviously the SLR allowed me to focus on the church and the other camera just smooshes the church on the glass. You gotta love that technical jargon eh?
