A couple of weeks ago, i printed out some of my photos in 8 x 12 format. Among the photos that i printed out, one of them was taken by my Fuji X10.
I probably should have had them printed out in 8 x 10 instead, since the long side seems ever so slightly stretched. It’s not noticeable, but i just feel that the photos would have been better served in 8 x 10. Lesson learnt for the next time around.
Printing out photos is far more involved then simply right clicking on a file and then clicking on print.
First and foremost, you have to take into consideration what the resolution of your photo file is. To do this, you will have to look at the properties of your photo file and then look under the details tab. Under the details tab, you will find the dimensions. Here, you will see numbers, such as 4000 x 3000.
With those two numbers, you will get your resolution by multiplying them: 4000 x 3000 = 12,000,000. Therefore, you have a 12mp photo and if your camera has a 12mp sensor, then you are getting the full resolution of your camera.
But how big (the optimal size) are you able to print such a file?
Well, to figure that out, you have to take into consideration Pixels Per Inch or PPI. On the most part, printing out with a setting of 200-300 PPI will get you optimal results – 180PPI should be used if you don’t know the PPI. In order to figure out how big you should print out your 4000 x 3000 resolution photo, you need to do some more math.
For example, if you were to print out your photo at 300PPI, you would take both numbers, 4000 x 3000, and divide each one by 300. This will give you the dimensions in inches of the optimal print size for your photo.
A photo with dimensions of 4000 x 3000 should be printed out, for optimal results, at 10 x 13. Of course, you can print bigger or smaller.
In order for you to better understand these calculations, here is a link for you to go to: (http://www.rapidnet.com/~rernster/information_about/print_size_calculator.htm).
Here is a photo of the photo that i took with my Fuji X10 and had printed out.
The photo that i printed out, was taken at f/8, 1/800ss, ISO-200 and 28mm (35mm equiv.).
The original file was 4000 x 3000; but after doing some editing, the file was reduced to 3832 x 2874 – i slightly cropped it. This equals to 11,013,168, which works out to be 11mp. Therefore, i lost 1,000,000 mp in resolution by cropping my photo.
If i use the website that i linked to and calculated how big i should have printed out (using 300PPi), i still get the same size of 10 x 13.
In the end, keep in mind that file size (MB/KB) has nothing to do with how you print out your photos. Rather, you have to consider the resolution of the photo and the PPI that you will be printing at.
For the first photo to be printed from my Fuji X10, i am very pleased.
Thanks for looking.
