Once a while I need to make a 2x2 for official document such as passport. It's annoying if I need to go CVS paying $15 for a digital while myself owns a whole bunch of lenses and am proud of myself of taking good photos.. well, I guess this is exaggerated feeling, it's like saying that doctors shouldn't let other doctors treat them.
Ok. So out of curiosity, I have always fallen back to GIMP to make a 4x6, thus 6 of 2x2, and print it for like 27 cents. So much satisfying! But since I don't do this for a living, it's totally new each time I need to do this. So, let's write this down once for all, so I can look it up next time, quickly.
Steps is straightforward:
Pick a photo with not-too-noisy background, because we will select using the intelligent scissor in GIMP. So the more contrast or clean the person is in this photo, the easier.
Select scissor (
i) and be patient. Close the loop by click left mouse on the very first point ← the mouse icon will change when you hover over that point. But honest, the point is so small that I can hardly follow it.
Click anywhere inside the loop ← this is the step I keep forgetting. By doing so, the selection will blink with dash line, now we are in business.
Paste selection into a
newfile. Now you should see only the selection, with like transparent background.
r) to a roughly square shape → this is the step you can position your head in the way that passport photo wants — so much for the head room, show some shoulders... don't worry if it's not mathematically square, just approximation is fine.
Some math (reference). Measure (
m) from the top of your head/hair to the bottom of your chin → 1172 pixels, for example → resolution of the new photo =
1172/1.1875 = 987 (pixels/in).
Create a new image:
- size: 6 x 4 in
Advanced, resolution to
987(see step above) ← ignore the warning that you are creating some 200+M file. It's ok.
Image→ Configure grid, sec to 2x2 in, and
viewto show grid. Tried grid offset to 10px, can't see the difference.
Select ALL of the cropped new photo (step #4), copy and paste, six times, in the grids. You see the result now.
.xcffile (as source), and export to a JPG.
Now just find a place and print a 4x6. Done, done, done!!
