A tutorial on image resolution pertaining to the Bloomington Photography club for the main club’s projector for the year 2014.
The projector's resolution is 1400 x 1050 pixels. This is a 4:3 aspect ratio that conforms to the general point and shoot. Most DSLRs are 3:2. And then there are the square sensors. This is loosely a 4.2 MP size and, as you can see, it really is much smaller than your camera's image. Most point and shoots are 6 MP plus. Many DSLRs are 10 to 36 MP. Square sensors with a digital back can be larger.
Naming the Folder:
- You can make it a top folder by using an exclamation point. Then add the month and your name.
- It can look like this: !Month BPC Your Name.
- This will make it easy to find, as some of you have many folders on your thumb drive.
Don't worry about these instructions. Send your pictures in as shot. Even those comfortable doing Method 2 or 3 don't always have time and just grab the images they want to show and put them on the thumb drive. But do try to make it easy for the loader to find your folder.
Resize (resample) in your editing program to 1400 for landscapes or 1050 for portrait view. If your program only has print editing, then choose in inches a 5 x 4 @ 300 ppi print or 6x5 @ 240 ppi or 10 x 8 @ 150 ppi or 19 x 14 @ 76 ppi.
The dimensions in inches with various standard ppi are approximations and all are slightly larger.
For those of us who just can't help it …
Copy the images into a folder on your computer for the club photoshare, assuming the images are in different folders. These images can be deleted later.
In Bridge select these images and go to Tools/Photoshop/Image Processor. In Photoshop go to File/Scripts/Image Processor and find your images to resize.
In the dialog box:
- Choose the folder for these resized images. They will arrive within that folder and in a newly created folder named “jpeg.”
- Ignore open first image to edit.
- Now check save as jpeg, put in the 1400 width and 1050 height in the jpeg area. Note: your picture will not be distorted. If your picture is a 3:2 aspect ratio, then in portrait or landscape mode -- whichever dimension is reached first -- the other side will stop before the maximum is reached for its side. This is similar to how your monitor sees an image.
- Check “convert to sRGB.” And at the bottom check to “include the color profile.” Note: Many cameras do not have a standard ICC sRGB, as the color engineers have altered it.
- Hit OK.
- Open these pictures to view. You may want to add a bit of sharpening, a change of saturation, and touch of contrast. When you have finished, rename the pictures by number and your name. The picture's name is not usually seen and the number will help decide the order the pictures will be shown.
Now send this folder to your thumb drive.
The ColorMunki is set to standard ICC colors as is Photoshop. So if your monitor is calibrated and you edit in a program that is set to standards and your picture has the correct profile for sRGB or aRGB, then showing your picture on the club's projector will offer an acceptable rendition from your monitor to the club's projector.
The images will race into Photoshop and be resized, the profile will be set, and the image will be sent to the folder of your choosing.
The pictures you copied there can now be deleted.
The newly created jpeg folder can be renamed for the photoshare. Make it really easy for the person loading your folder.
If you stumble with this method but would still like to learn it, contact a Photoshop mentor and the process can be shown to you or described better to you.
The method used in other editing programs can be, and should be, listed. There are Lightroom, NIK, Picasa, various MicroSoft programs, and your favorite not listed here. Just write up your method and it can be included here.
