Resizing will not help your photo

Is it true that resizing a photo from VGA to higher megapixels is not the same as originally shooting the photo at a higher setting? Resoultion is lost when you resize to a bigger size.

Think about it logically. If you shoot a picture with your camera settings set to capture 640x480 pixels of information (just over 300,000 pixels), can you later go to your computer and somehow magically multiply the amount of information you have gathered to millions of pixels? No, what you can do is force the computer to extrapolate the information the missing pixels would have contained, but this mishmash of averaging, interpolating and guessing will not add data. The only way to maximize the size and quality of your captured images is to use your camera's highest image quality setting all the time. You can always resize down (throw away pixels) but you can never go the other way.

I do beleive people intelli...Its more than one persons opinion that I always look for. Do you feel better when one person tells you the truth or when 10 people tell you the same thing??? now mr. Strangehost, I always thought the camera automatically compensates for lost pixels when you upsize. I never expected the computer to duplicate a larger pixel picture from a vga size.

Ruler,

Even if that were true, the camera's not doing the upsizing, the computer is.

If you want a practical, real-world example of what's happening, look at a color photograph in a newspaper with a magnifying glass; you've made it "larger" but the "stored data" is the same, and it looks all grainy, see?

Always shoot your images at the highest resolution you can confortably store on your memory chip, then later downsize the images in the computer. You can't go wrong this way, as long as you "save as" and keep the original file virgin so you can go back to it if you need to make a larger print. Also, for DPC, you MUST have a virgin, unaltered image to validate your entry if it ever ribbons or is challenged.

If you tell the camera to capture 300,000 pixels, that is what it will do. It doesn't stash a few meg extra somewhere just in case you want them later.

I am having a very hard time understanding what all you are saying and asking.

In any event it is clear that you are lacking some very fundamental unsderstanding on how digital cameras work.

If you go to this link you will find a pretty good tutorial on using digital cameras.

Make sure to look through all the pages, there is a next page button at the bottom.

Strangeghost is right. The resolution at which you take a picture is the best you will get from it. The is no adjustment in the camera to add back in information to a picture. That is the decision that must be made in deciding resolution: Image size vs. resolution. They are directly proportional.

yes bear, I am understanding now. The camera or computer enlarges the photos and it loses pixels. I learn so much from this website. It was a great analogy you made with the magnifying glass. That one comment did not make me confused anymore. I will store all originals on my computer so I dont clog up my memory stick in my camera. thanks dude.

It's all about density. If you would have to do fine sculpting, wich one will give you the chance to make fine details, cheddar or swiss cheese?

hey scott..thanks but no thanks partner.

Then get ready to see holes (empty pixels) with your sculpture (photographs)...

If software or cameras were able to accurately interpolate data when an image is enlarged, then there would not be much of a difference from a 1MP and 12MP camera

Ive read a thread a while ago. The person said shoot your photos in vga to save space and resize to a bigger size if you need a bigger print. Threw me off. Its not hard to understand why I started a second thread

Don't you have anything better to do than critisize people for trying to learn? If it bothers you so much ignore the thread.

Second what Joe said. No need to jump all over Ruler. If the thread bugs you because you've seen it all before, ignore it. Some of us don't mind answering questions every time they come up.

Joe/Ruler, sorry if my post was read as being critical. I really wasn't. Believe me, I'm no expert myself and often need to hear things a few times. Forums are a great way to do that, but another good one is just trying ideas yourself and looking at the results and differences. Another helpful approach for me has been going through the archives and reading about how the ribbon winner's composed their shots. It's always sad when you see a "N/A" under the description.

But the size issue took me some time to comply with before I found an external hard drive to dump my work. Before that, I was getting worried about filling up my internal drive. I tried the CD route, but the external drive is just too easy. I do use CD's for the special image backups. So, with that, I feel OK operating on the largest size and just carrying more memory on a shoot.
