I just downloaded the Photoshop CC 2014 trial in the adobe creative cloud app and I photoshopped my first picture. After saving it I opened it again and now it appeared blurry. After trying everyting it still appears blurry when I open the file. How can I open the file and get quality it was before I saved it?
Go to the menu Image then Image Size. Look at the pixel dimensions. The lower that number is the more blurred it will look as you need to zoom in to see it better.
Using the crop tool will lower that number. It is better to stay close to the original image to have a sharper image.
If you start with a low quality image and increase the pixel dimensions the image will get blurry as that is similar to zooming in.
Could you please post the image and a screenshot taken with the image open in Photoshop at View > 100%?
