Is there a circle crop tool on Photoshop?

holeinone1972 · January 20, 2007 11:16AM

I always wonder how some of you folks get those nice tight circles around your coins.

Is there a circular phot cropping tool on photoshop, or am I stuck with the square one?

I have photoshop 6 I think.

Use the circular selection tool to crop.

Then invert selection and whack at it with the eraser.

In Elements its on the tool bar, the default is the square l tool, right click and should be selectiion for elliptical marquee tool. Once you open the coin crop it as close to the edges as you can before you use the marquee tool. Start in the upper left hand corner and drag it toward the opposite corner. You will have to play around with the mouse and go through several undos before you get the gist of it. One of those things that takes practice.

Or you could just fill the background with white.

click and hold on the square selector tool ... it will give you the circle option. When using the circle selection tool, hold down the shift key and you will get a perfect circle instead of an oval.

I didn't know this. Thanks! I always crop to a tight square around the coin, then use the circle selection tool from corner to corner. Copy and paste into new picture with white or transparent background.

Crop circles are the work of aliens.

holeinone1972 · January 20, 2007 12:27PM

OK I had to go into image ready, whish I never use.

But there i found a circle marquee option.

Here is the result:

holeinone1972 · January 20, 2007 12:45PM

That circle thing takes some practice.

I figured out the transparent background now.

I think, LOL

Just draw a rough circle, then choose select->transform selection and you can fine tune the circle. You can draw it in a perfect circle by holding down shift. You can draw from the center outward rather than corner to corner by holding down alt. Draw a perfect circle from the center outward by holding down both shift and alt.

holeinone1972 · January 20, 2007 1:14PM

Thanks for the help.

The "Marquee" tool is usually in the top left box in the two-column toolkit. If it is displaying as a square (rectangle), right click it and select "Elliptical Marquee Tool." The set the Style (in the bar above the open field of the window) to "Constrained Aspect Ratio" of 1:1. This will give you a circular selection tool. The tool takes a little getting used to ... first you drag the mouse to get a circle the right size, then you can move the circle by positioning the mouse right on it, waiting for the pointer to change to a dot, and then dragging it.

Once you have the circle where you want it, select the inverse (i.e. everything but the circle) by clicking Select, then Inverse (or use shortcut Shift+CTRL+I).

Once you have selected the inverse, click Edit, then Clear (or use shortcut Alt - E - E).

Once you clear the background, click Image, then Trim, then hit Enter. This will crop the image automatically to a square, the same size as the diameter of the circle.

I hope this helps. Here are some crops I have done this way:

Best,

Actually if you click on the circle tool and set it to "fixed ration" then you can size a perfect circle by chaning pixels...its around 800-1200 px for a Morgan dollar. Then you can do the obverse and reverse really quickly and dont have to mess with the Shift key. Plus, if you wana splice the pictures, set the canvas to doulbe the PX set for the cirlces and add a few, and your crop will be extremly close to the coin...

This one isnt perfect but its pretty close

holeinone1972 · January 20, 2007 10:34PM

Thanks now all I need are some monsters to post.

IGWT · January 20, 2007 10:39PM

Nice job, Robert; and I like the coin, too!

OK, are there any other great photoshop secrets or hints?

IrishMike · January 20, 2007 11:54PM

Depends on whether or not you want to have a white background, you can click on the boxes at the bottom that show color adjust them to the color you want, then click on paint bucket and click on in the area you want to change the color to.

holeinone1972 · January 20, 2007 11:57PM

Got it

IrishMike · January 21, 2007 12:00AM

Heh looks like we are turning you into a photo-monster.

IrishMike · January 21, 2007 12:01AM

If you resize the coins to the same image that works better when you do a merge.

airplanenut · January 21, 2007 12:57AM

My way feels much easier...

Crop the coin tightly with the crop tool--I mean have each side of the crop tangent to the coin.

Take the elliptical selection tool and put the crosshairs in the exact center of one corner of the image. Click and drag diagonally to the opposite corner. This typically drags the ellipse right around the coin, and there's rarely much, if anything to delete. If there is, I usually start in another corner, select the coin, and invert the selection and delete a bit.

I always photograph both sides, do any slight color corrections neccesary to make the image accurate due to lighting/CCD on the camera being used, use the square selection tool to cut out everything but a small even border around the edge of the coin, repeat for second photo. Then I take the obverse image, resize the canvas 200% anchoring the obverse on the left side and then slide the reverse image onto that new blank piece of real estate on the right side. With proper lighting and photographing on black velvet, you don't need to do the whole circular crop/fill method (which also allows you to better reflect the reeds or edge lettering on some issues). Below are two examples, the top is the result of the above with a raw coin and the bottom all slabbed up.

Google 'photoshop tutorials' and the lesson will never end

In photoshop elements, I use the lariat icon, click it to switch to magnetic, then on tools set difference to 5 pixels, edge contact to 70 and frequency to 60 (these settings will stay until you change them), then just drag the magnetic lasso around the coin and it goes to the edge on it's own. Double click when you've gone all the way around the coin then crop. I've also found that when you resize the picture, leave resample unchecked and it will automatically use all the pics from the hi-res pic in the smaller picture/

<< Then invert selection and whack at it with the eraser. >>

You don't need to use the eraser tool. I always use a black background. Many use white. Choose whatever color you want as background color. While your selection is inverted, press and hold the shift key and press F5. This will erase the background and replace it with your background color. Invert again and then crop. If it doesn't crop to the edge of the coin, then crop again. Then de-select and you're done.

I didn't start using photoshop (ver 6.0 for me) until last month. Got a legit copy, full and not upgrade, and have started trying to use it.

This was a great, and timely, TTT ModernCrapNut, and I thank you, and those that gave suggestions and started the thread, very much!
Special thanks to RobertPr as his suggestion was exactly what I just tried and it works simply, quickly, and nicely!

Thanks all!
