Question about Canon EOS-5D Digital Camera
I have a Canon 5D. When clients ask for high resolution the Canon has a resolution of 72, and there is no control on the camera for ,say ,300 or more. What does this mean in terms of the full frame camera? Can I raise the resolution using Adobe Photoshop? How high can I go. 1200?
I have a project that requires enlarging the photos to, 2 by 4 feet. How can I get the best resolution and pixels for this task?
In Photoshop go to IMAGE in the menu then select IMAGE SIZE. Check the three boxes on the lower left eg .resample. Under DOCUMENT SIZE change the right column to inches and change the left column to the size you want. With "constrain proportions on" you only need to enter one dimention and the other will change automatically. Change the RESOLUTION to 200 or 240 and select bicubic smoother. You will double the resolution in pixels, but are not improving the sharpness of the image in any meaningful way.

The 5D has a 12.8 mega pixel sensor.
2 x 4 ft. is 24 x 48 inches, so you have to cover 1152 sq. inches using 12.5 million pixels.
Spreading 12.5 million pixels over 1152 sq. inches means 10,850 pixels per sq. inch. Taking the square root gives you a maximium resolution of 104 pixels per inch (or 'dpi')
Photoshop will allow you to increase the resolution by a process known as 'interpolation' .. increasing to 300 dpi using Photoshop before printing will give a better result.
NB. Depending on your printing process, you may end up dealing with files up to 500Mb in size ....
