  • While editing a picture there are various actions which can be done inside a photo editor. Depending upon the photo editor there will be more or fewer facilities. Ordinary editors will crop, resize, brighten or illuminate the pictures while advanced editors like Photoshop can do miraculous changes to the quality of a picture.

    The size of a picture and pixels are interrelated. For a given size the optimal size of pixels is there. In that case, the picture will be in best resolution mode. Now if we keep the size of picture same but reduce the pixels then the quality of the picture will start deteriorating. So to maintain a good quality picture an optimal number of pixel matrix is required. Pixels can be thought as the small points very near to each other within a picture present into an array (length x width) so that they constitute to make a perfect picture.

    If we reduce the size of a picture the number of required optimal pixels will also decrease in a proportionate way. So if you require a clear thumbnail type of picture to insert somewhere in a small place, few pixels will be sufficient of course again connected to that size only.

    The high-resolution big size pictures can go up to hundreds of MB while high-resolution small pictures will be a few MB or even will be in KB. So the space a picture takes in your gadget or computer is dependent on the combination of its size and pixels.

    Aspect ratio is how you want to keep this array. Whether you want more in the verticle side or horizontal side. Depending on this the picture will be seen more on the verticle side or horizontal side on the screen and as per one's choice, this aspect ratio can be selected. The most common aspect ratios used in videos are 16:9 and 4:3.

    Knowledge is power.

  • Aspect Ratio is ratio of the screen to its shorter side. Most commoy used aspect ratio is 16:9 and oldest aspect ratio is 4:3. For high resolution A4 page is selected which prints wuality is good. The term resolution is often used for pixel count for digital imaging. Pixel is a smallest, controllable element of picture represented on the screen.

  • It all depends on what size of page you wanted to print the photo. Nowadays photo editing softwares like photoshop comes with suggestions of aspect ratio w.r.t. resolution required. Also the printing companies also do ask for required resolution of photo before printing for big hoardings.

  • Photo editing is a vast subject that cannot be explained in one such thread.

    A. What you do with the photo depends on the mode you have shot it and what are you going to use the image for.

    People take pictures in JPEG/PNG mode commonly. Professional take in RAW format. The file size of a picture varies in ascending order from GIF, JPEG, PNG, RAW and so do the outcome of editing. Pictures taken or stored in GIF format cannot be edited very well.

    If you are going to upload the image on the net, then you can edit, sharpen etc but if you are going to publish the image in a magazine, then it would be converted to CMYK format. Most experts do not sharpen the image in the camera or on the photo editor but do it after conversion to CMYK format. So, what you do depends on what you have and the final indented use of the image.

    B. The quality of the editing, of course, changes from the various free software that you get and the professional adobe photo editor that wildlife and photography experts use.

    Adjusting the pixels, resolution and resize need to done alway bearing in mind that the resultant image with not be of the same quality of the original JPEG or PNG image.

    C. As far as pixels are concerned, it is the tiny unit that carries one of the basic colors (Red, Green, Yellow). Most images are set on the standard format ration for optimal viewing. For instance, the common image we are all used to is the 4inchx6 inch picture. If this is printed at 300 ppi (300 pixels per inch) that gives a good quality print then the image will have 1200x1800 pixels

    The common settings that are used based on image size are as follows. You can use these settings. Please read it as Image size in inches followed by pixels for a good image and pixels for a high-quality image
    5x7 image-900x1260 pixels-1500x2100 pixels
    6x6 image-1080x1440pixels-1800x2400pixels
    8x10image 1440x1800 pixels-2400x3000 pixels

    D. The image size ratio that most people use is 4:3, 16:9 and 21:9.

    E. The practical way to learn photo editing and image re-sizing and adjusting the pixel resolution is by trial and error. Select a good image and then try the above and view the final image on the computer and an actual print out, this will help you to get the hang of it.

    F. As far as cropping, sharpening, color, light change etc goes, for beginners, it is advisable to undergo editing rather than overdoing it. Please remember that the final image will look different on the computer screen and the mobile screen( images on mobiles look more sharp, perky and with a touch of little more color).

    Among the many photo editors, PhotoScape is a good free download tool for beginners to get good images. Here you can edit the image and resize in standard acceptable options that the experts use.

    G. Lastly it is useful to know that even a good image added to a power point, word file etc will suffer some loss of quality if we choose the 'compress image' option finally to save disk or storage space.
