 Posted: Wed Apr 27, 2005 3:57 pm Post subject: Cropping Photos |
 |
|
OK so here's the deal. Let's say I have a digital picture that's 3264 x 2300 pixels (random numbers) and I want to make it a 6in x 4in so I can print it out on photo paper. My point is that the picture starts off bigger than 6 x 4 and I wanna crop it to that size. When cropping in photoshop...there is the height, width, and RESOLUTION option. What should I make the resolution option??
Should the resolution option always be the same as the original res ??? (when you go to image size and see it in there)
Thanks |

Are you running elements or full photoshop 7;cs;cs2 ?
what is the resolution of your file?
Do you require a high res photo?
What printer are you using ?
I ask all these questions as to give the best answer to your question I need to know what system you are running.

All that I'm concerned about is how to properly crop a photo down to 4 x 6 and keep the photo looking the same (as far as resolution). Thank you |

General consensus on printing resolution is between 180-220 dpi. I tried all sorts and now work at 180 dpi even with 16x20 prints no problem. The other side of the story is the printER resolution which I do increase for larger prints - it uses more ink but that's what you pay for if you want quality. In your case for 6x4's you shouldn't see much quality loss in any case so keep it low and speed up the work if need be.

lilmikeeboy - A widely accepted rule of thumb is that for prints, 300 PPI is the best target (if possible) resolution.
Your hypothetical pixel dimensions of 3264 x 2300 would translate into a 6.303 x 4 image so you would have to crop off a little of the long edge to fit into your 6 x 4 specs.
It’s real simple, use the crop tool and click on "front image" (in PS 6) and set your 6 x 4 inches with a 300 resolution. It will be resampled down.
I have heard that anything over 300 PPI is really overkill for inkjet prints.
Now if you don't have enough pixels to achieve 300 PPI, that’s another story. |

The term "crop" has been used in this thread, but "resize" may be a better approach. Cropping removes some of the image to produce a smaller size. Resizing (via Image/Image Size) will make the image smaller without removing anything. Uncheck "Resample Image" and the resolution goes up if you make the image smaller or down if increasing the size. If checked, the resolution doesn't change. |

You are correct jarhtmd, but if the image does not fall into the exact print dimensions of 4 x 6, then some cropping would be necessary.
The way I would do it would be first, go to image size, uncheck resample, set the res. at 300, then check resample, and set one of the image dimensions at 4 or 6 , and if it ended up something like 6.3 x 4, then set your cropping tool at 6in x 4in x 300res. |

You do not need to make the res option anything because PS will calculte the RES for you. THE MOST IMPORTANT thing you should be conserning yourself with right now (and every time) when you are cropping photos is DPI or dots per inch when you scan it in from a scanner, or take the photo directly from your camera. The best DPI is 300 for prints.
NOTE: The camera's print dpi MAY SAY 72 DPI when you first look at it in Photoshop and that is ok, because photoshop it self will re-calcultate the dpi to the photo on to paper to match (or it's best guess) of 300 DPI. It may go down some. 150 DPI Is the minum you can get away with btw for prints.
PLAY PLAY PLAY is the best advice i can give you. Photoshop has an UNDO function JUST in case if you did not know that. Remeber to ALWAYS duplicate the background photo that way if you screw up BADLY, you will have something to go back to.
Hope this helps,
