I goofed!! I worked so long and hard on my photo as a painting photo, and as I was putting the finishing touches on it yesterday, it sickened me to realized that I made a mistake.

I had been saving as I went along.

I usually make the mistake of resizing to 800 pixels, and then I keep tweaking things, and before too long, I can't go back and undo, because I've done too many commands since the resize.

I was NOT going to let it happen on my painting! I was so very careful. I saved frequently. I resized frequently, because it looked so different small than the beautiful full sized creation. Then one time I decided to see what an effect looked like applied at 1200 pixels and then resized down to 800...

I resized to 1200, did some work, resized to 800. Remembered to not do anymore work after the 800 resize. Undid the resize, saved and went on my merry way.

An hour an a half later -- I realized my work was 1200 pixels, and I wanted to cry.

So I'm stuck at 1200 pixels.

I want to print out an 8x10.

At 240 pixels/inch resolution, it thinks I can print out a 3x5.

I'm going to print out an 8x10 anyway. What's my best chance of not throwing up when I see the print? Do I "resample image"? Do I print at a lower resolution?

I hardly ever print anything, so I have no idea what the best way of handling this is -- any input would be greatly appreciated.


It's there on my screen looking all pretty. Why can't it remember it big??

resolution = 200
height = 10 inches
resample bicubic smoother

[results are not going to be pretty...]

best to start over full size, then size down for dpc.

I also edited mine at a smaller size, mainly so that my wimpy computer could perform an HDR merge, and because I knew I'd have a lot of adjustment layers with masks.

However, since I sized it to exactly 25% of the original, I think I can upsize the smaller image to 400%, and then copy over the adjustment layers with their associated alpha channels/masks and recreate it at full size without having to make all the masks over again.

DPI Quality Description

200+ Superb At or near the finest quality possible.

150-199 Excellent A typical photographer will see no difference to a slight difference when compared to superb.

100-149 Better Better than Good, but not as good as Excellent. The typical photographer will be thrilled with prints of this quality.

80-99 Good Quality that a typical photographer will be happy with.

79- Fair Quality will depend on the individual photograph. For large size prints the typical photographer will find them acceptable, but the sharpness will not be as high as a Good quality print. Compelling subject matter may trump the loss of sharpness.

Oops....realized I didn't answer the question. :)

1200 pixels at 5" puts the resolution to 240 dpi (superb)

Going to 8x10 puts it at 120 dpi (better), and according to the description: Better than Good, but not as good as Excellent. The typical photographer will be thrilled with prints of this quality.

Unless you aren't "typical" heh heh.. :)

Sharpening radius estimator: //www.cambridgeincolour.com/tutorials/digital-photo-enlargement.htm

If you run the calculation with 1MP, and 1 meter, you are looking at a minimum PPI of 87 with maximum size of 15 ".

The whole point is that how big you print and at what resolution is dependent on your viewing distance. I doubt something at 8x10 will be looked at a few cm from your nose. :) So...you should be fine.
