Close-ups

I am slowly going through some files over at the other board and adding those of my interest, for further reference

--------------------------------------------------------------------------------

Hi there,

Ok... here is a weird question

Is it possible to take a close-up of a photo?

Let me see if I can explain:

- Usually when I take my photos I would chose a large document size, making it easier to work on the pixels.

- With a large document size, one can zoom-in quite considerably and still view a good quality of the image.

- What I would like to do, is bring forward a particular object as much as I can. Making the "zoom-in/close-up" a new/separate photo.

Did I explain properly Razz

So how can I take a snap-shot of the close-up? Other than using "Print Screen"

Thank you

Well, I sure missed seeing this one! There are a couple of things you can do:

1. If you are working with an image on your camera's memory card, you can load the image file into a folder on your computer and then load it into Photoshop. There are 2 ways to approach this:

a. In Photoshop, crop the image, to include only that part of the image that you want and then save the cropped image as a .tif or .psd in "Process Multiple Files" (File > Process Multiple Files) at the highest resolution your version of Photoshop has (probably 600dpi). Then, read the saved image file into Photoshop and increase the image size to the dimensions (Image > Resize > Image Size) you want with "Resample Image" unchecked. You may or may not need to use a slight amount of sharpening when you are finished to maintain the original quality you had before increasing the dimensions of the photo. Or,

b. In Photoshop, save the entire image as a .tif or .psd in "Process Multiple Files" (File > Process Multiple Files) at the highest resolution your version of Photoshop has (probably 600dpi). Then, read the saved image file into Photoshop, crop the image to include only that part of the image that you want, and then increase the image size to the dimensions (Image > Resize > Image Size) you want with "Resample Image" unchecked. You may or may not need to use a slight amount of sharpening when you are finished to maintain the original quality you had before increasing the dimensions of the photo.

Note: If doing a. or b. above causes the image Resolution to go to less than 240pixels/inch, go back to the original image and choose dimensions somewhat less than what you want until until you are above 240pixels/inch. Then, increase the image dimensions by 10% and also increase Resolution by 10%with Resample Image unchecked. Repeat this process until you reach the dimensions you want. You may need to apply a small amount of sharpening when finished to retain the original image quality.

Example: I took the following photo and cropped out only that portion of image that I wanted, resulting in reducing my photo from a 26.7" x 36.6" photo to a 9" x 12" photo. Then, I saved the 9 x 12 inch image as a .tif file at 600dpi using "Process Multiple Files", loaded the saved image back into Photoshop and then doubled the size of the dimensions to 18" x 24" with Resample Image unchecked, resulting in an image resolution of 296pixels/inch. I applied a little bit of unsharpen mask and adjusted the color curves slightly, and this is what I got:

Original Cropped and Dimensions Doubled

2. If you are working from a printed photo and have a good scanner, you can scan the photo, saving it as a .tif file at a high dpi - like somewhere between 800 dpi and 1200 dpi or a little more. Select to scan only that portion of the photo that you want with the dimensions proportional to the final dimensions you want and then use Photoshop to increase the dimensions to what you want them to be as instructed in 1.a. above.

Note: do not attempt to do the above in .jpg file format. You need to convert your files to .tif or .psd (if using Photoshop). Don't just save them as .tif or .psd, do it as instructed above. Personally, I always use .tif format.

Thank you Repa.

Wanted to let you know that I did part of what you suggested as I did not see this post in time. Will try your steps more throughly and let you know.

Merci Smile
