O.K......I suppose I need to do a WHOLE LOT MORE READING, because I'm totally lost when it comes to some of the nomenclature you're using. Such as "interpolation," "algorithm," "aliasing," "RAW," "JPEG compression," et.al.
I took the photos, then used a program that came with an old Olympus 3.2 MP camera I bought about 10 years ago to download them to my PC....so I suppose that's the root cause of some, if not all of my problems, you suppose? I use it because I KNOW HOW to use it. Part of the "Old dog, new tricks" syndrom, I guess. I then took them to "Print Shop" to downsize them to a usable size for posting. hehehe....I can hear the groans all the way here in Idaho!
I did NOT do any editing to them, such as saturation, contrast, sharpen, or anything. Really, I DIDN'T! They're all full size (as in not cropped), although I did resize them to 600x414 for posting purposes.
I also have the program that came with my Olympus 14MP "pocket camera" that I can use to download/resize them, but have never tried that option. I also have "Photoshop," for what it's worth. But, from what you've said, none of the methods I've used so far is acceptable, right? Dumb question. The results so far would indicate IT ISN'T ACCEPTABLE!
I guess the good thing is....I CAN get rid of the "jaggies," it's just a matter of learning some new techniques to download them, resize them, new camera settings and so forth, right?
Jeez....so much to learn and such a small amount of grey matter.
Thanks for the tutoring. I appreciate it more than you realize.
Again, I apologize for not contributing anything to the site other than to ask questions.
