If an image isn't big enough (doesn't contain enough pixels), then you must somehow add pixels to it. You said: "The new pixels should not be created when you want to enlarge an image that is not big enough."Īctually, if an image is "not big enough" (if it doesn't have enough pixels to print at your desired size and at the recommended printer resolution), then you MUST select "Resample," input the desired image size, and let Photoshop add pixels! That does affect image quality somewhat, but in reasonable enlargements, you won't see major problems.Īll of photography entails compromizes. It usually doesn't hurt if the resolution is larger than 300 ppi, except for publication and some printing services. If the resolution is then less than 300 ppi at that size, you need to check the "Resample" box and change the resolution at that size to 300 ppi. If you need a specific size, you need to set that size in Photoshop/Elements. You don't have to do anything if you "print to fit" - the printer will handle these calculations for you and maximize the print area. You can change the size or resolution without any loss if you use Photoshop/Image/Image Size and uncheck the "Resample" box. The same image can be represented by a low resolution (e.g., 72 ppi) and large size (as you observe in Elements) or high resolution (300 ppi) and a smaller size - about 7x10 inches. If you set any two variables, the third is fixed.Ī digital image best described by the number of pixels on a side - 2000 x 3000 pixels for example, for a 6MP image. Pixels = Length (inches) x Resolution (ppi) Size, resolution and the number of pixels are related as follows:
You can also reopen and click on on a layer and rework it.
You can save in PSD format with layers and adjustment layers intact and open and close as much as you wish without loss unlike JPEG which has a loss each time. Psd is the file extension and I also use it as the end of the name so I can identify it easily from the otiginal.
Open the camera file and first thing is "save as" and rename it such as img 235psd.psd. Then do brighness contrast adjustments, color balancing, levels, curvers, layers, masking tools and masking, layer masking. If you have CS2, I recommend Photoshop CS2 for Dummies to start.ĭo the basics first and learn where all the controls and tools are. How long does it take to learn to play a piano? Same thing. I learned more in 4 months retirement than 2 years working. How long it takes depend how good your memory is, how good your instruction is, and how much you practice.
