Interim show #3: Enlarging an Image for Print

March 23, 2017

Our third and final interim show opened yesterday!

I used previous shows to show case my work so far, thinking about the content of the images and the artist statement that went along with them. However, at this stage because I know so strongly where my project is progressing I became more conscious of the quality of print. I am considering presenting one large scale print for the graduate exhibition at the end of the academic year, so I took the opportunity to experiment with enlarging an image for print.

Unfortunately my experiments came with little success, when enlarging my print it became soft, in an attempt to resolve this I added a high pass filter. Thinking this had sharpened my image, I went a head with printing it. After I received my print, with no time to change it, I realised I had used the high pass filter too heavily and went from a too softer image to an image that had printed almost pixilated. Having to show something I did have to pin the poor quality print, but this is why we do the interim shows, now I have learnt how to resize images for printing properly.

How to resize an image correctly.

With not ever having tried to print an image of a large scale before, I thought I could resize it all in one go on Photoshop. This I found out was the incorrect way, because to get to the new size Photoshop pulls apart the original pixels and adds more in. The colours of these added pixels are a blend of the existing, this is why sharp edges become soft.

The correct way to resize an image is to increase the size by 10%, save it and repeat, until you reach the required size. By doing it this way not as many pixels are being added all at once, therefore colours stay solid and edges sharp. In turn by resizing this way, for myself, the need for the high pass filter was eliminated, but if you do need it I would recommend only using it slightly.
