I have entered my first challenge and noticed that I'm getting some focus/compression comments. My photo looked much clearer until I shrank the file to meet the size requirements for submission. Would it have been best to shoot at a lower resolution? Or just crop out a smaller portion of the picture to meet these requirements?

Thanks.

What software did you use to resize your image? What compression options did you choose when you resized?

I used The Gimp. We've just switched over to this software (Linux based computer) and I'm still learning how to work with it. I ended up just doing a percentage shrink of the full size image until the pixels were within the challenge parameters. I believe it ended up being a straight 44% reduction.

This kind of stuff is easily handled in and version of PhotoShop.

How many btyes did you file end up at? It may not have been the resizing as much as the amount of compression you used when you saved the photo.

I also will often sharpen a photo after resizing.

When resizing using Image->Scale Image, be sure to select the "cubic (best)" setting from the menu at the bottom of the dialog. Linear will not give you as good results. Also, check the "preview" checkbox in the "Save as JPEG" dialog - that will show the file size at the compression setting you've set with the "quality" slider. The game is to get the size as close to 150kb as possible without going over.

most image editors have a compression utility that will allow you have have an image that is 640 pixels wide and 4xx pixels tall and you can adjust the quality until it gets to 150kb. Most of my images are saved at a quality of 97% (100% being the highest quality) once I resize it to the 640x4xx size.

So you should resize the image first to meet the pixel size requirements, then do your sharpening/un-sharp mask utility, then save it using the compression/quality tool or what ever it is called.

Thank you. Like I said, I'm still learning this software. Plus, I wasn't entirely sure how much editing I could do as far as sharpening the image, etc.

You have all been most helpful.
