I want to make my images bigger

Postby Willy wombat on Wed Apr 25, 2007 12:34 am

I would like to print some of my images at a slightly larger size and need to get my short edge to about 2500 pixels (from 2000). I was thinking about dropping resolution to 250dpi (from 300) and enlarging the image size. Is this right?

What is the best process to do this using PS2? Are there any tricks i should be aware of?

Cheers

You can safely print at 200dpi without any discernable difference and honestly, some print houses will only accept 200dpi.

Further, there's the 110 percent method which works a fair few amount of times. Go into image size, change one field to percent (which should do the same to the other) and type in 110. Press enter. Do the same until you reach your desired size.

Or you could take a look at interpolation software.

I have printed at A2 without any noticeable drop in quality (you stand back anyway to view an image this size) from a Pentax *ist DS (2000x3008). Don't worry about it with such a small change in DPI.

Leigh the 110% method seems to work quite well for small increments.

The method Leigh mentioned works really well most of the time. Otherwise there's always Genuine Fractals which does a better job. There are other Photoshop plugins that do the job well too.

There is a method reputedly better than the 110% method providing you have PS CS or better. Go to image size and uprez your image....say, if its 300dpi then make it about 360 dpi. Change sharpening mode to bicubic sharper and type in new size. This is from memory so give it a go and compare it to the 110% method. Let us all know what you think.

Hi Matt - Thanks for this tip - It seems to work well also. Why is it a "better" option. Does increasing the DPI preserve the detail better?
