You could tell because low resolution makes for a pixelated picture, and high resolution settings, you cannot tell.
Image > Image Size
Open image in Photoshop then go to Image > Image Size.
no they record at the same rate but the low resolution is of lower quality and smaller file size than the higher resolution image.
go to http://www.shrinkpictures.com/ its a online image resizer and you can set the size and image quality. hope this helps
Low resolution is usually caused by a poor compression rather than poor capture. Low resolution images have less physical pixels than a high resolution one. The stretching of the image is what causes them to look poor. This low number of pixels is usually the result of downsampling of the the image for email or file size purposes.
resolution is number of pixels in other words informations about image per inch, cm. Low resolution means low number of pixels or informations per inch and generally low quality of image.
They had a low resolution
The best way to decrease the resolution of digital artwork is to open it with Adobe Photoshop. Then go to the top of the screen and click Image > Image Size > and change the number in the box labeled "resolution." Be sure that "Resample Image" is checked so that it will discard the extra resolution, rather than reallocating it. Then Save As, and you're done.
No, only on the quality. If you have a picture that is in low quality, perhaps because you scanned it that way, printing in high resolution won't be able to improve the image quality.

You need to shrink the picture down and take a High Def pic of it. DxO has something, never tried it, but here is the URL: "http://www.dxo.com/intl/photo/dxo_optics_pro" it has a trial or you can pay like $14.00.
