At my camera club on Tuesday evening I was asked about the method I use in Photoshop for upscaling my photos so that they can be printed at larger sizes than would normally be possible from my 6 megapixel Nikon D40 camera:
I promised John Garner that I'd post the method so here goes:
I use Photoshop CS3 but you should be able carry out the same steps using the latest versions of Photoshop Elements:
"Open the photo that you want to scale up and go to 'Image' then 'Image Size'. Set image resolution to 300 pixels to the inch.
In the relevant boxes enter the final dimension of the print that you want multiplied by 120% and set the bottom box to 'Bicubic Smoother' and tick the 3 boxes just above it. (eg if you want a 30 inch wide print the calculation would be 300 pixels x 30 inches x 1.2 = 10,800 pixels which is the figure you'd enter in the 'width' box
Final step: once the image has upscaled to the 120% mark you then take it back down to the 100% target size using 'Bicubic Sharper' (eg you resize back down from the 10,800 pixels of the previous example to 9000 pixels)"
I hope that helps John!.....as long as your original image is sharp you should find that you can get consistently great prints at sizes of 30" x 20" from a 6mp original photo.
