#HOW DO I RESIZE A PHOTO TO SMALLER KILOBYTES IN PICASAS HOW TO#

(b) how to set Resolution number? I set 180, get a small size file, but if I set 350, get a very large file. What are the suitable numbers should I use? setting width=24 inches, height=16 inches will have a much bigger files of setting width=18 inches, and height=12 inches. (a) how do I set the width and height numbers? I noted with different width and height numbers, the document size significant changes though having the same ratio, e.g. (2) Then I click "Image=>Image size", set "document size" with width=18 inches, height=12 inches, and Resolution =180 pixel/inches, then click OK, the file gets to the ratio I want. (1) crop the file as I needed, without ratio constraint, but I tried to to get close to 2:3 ratio, I nly worked out one approach as Colin suggested. I have tried several ways as you suggested, but so far

Note that with this approach the aspect ratio of the image has not changed, all we've done is mask out the top/bottom of the image. This will add the chosen colour to the top and bottom. Once you have made your selection, invert the selection (Select->Inverse) and then fill the selection with black/white/whatever using Edit-Fill. menu to fill the top/bottom or left/right sides with black or white or transparent, to get the photo back into a 3x2? I feel this would damage the image less than a resize would.Īlternatively, if you happen to be doing crops that keep the width of a landscape shot (so, for example, taking a 3x2 and doing "a Colin" to turn it into a 2x1) one way to add the black/white/transparent top/bottom is to use the selection tool with the fixed ratio style, and width=2 and height=1. Can't you crop your photos down to whatever you like, and then use the Image->Canvas Size. PS CS4 seems to warn that this setting is only for preview purposes, so I imagine it's simply not usable to help us achieve what Yan wants.) However, there is a tick box that allows the ratio to be used or not, View->Pixel Aspect Ratio Correction, so the pixel data is not changed at all in the saved file. (EDIT Note, playing with Photoshop, I get the impression that the aspect ratio is read from the file. I guess I am only saying that Picassa doesn't read or understand the aspect ratio metadata. I would predict that the image files differed only in a few bytes, and that the majority of these two files would be (identical) pixel data with the same number of rows and columns. We could test this by comparing two images, one with a square pixel aspect ratio and one without. The custom pixel aspect ratio setting (View->Pixel Aspect Ratio->Custom Pixel Aspect Ratio.) I imagine just sets some metadata somewhere that tells applications the ratio between height and width (or width and height, who knows!) I'm then guessing that Picassa doesn't know that the pixels are no longer meant to be square. I have never used the custom pixel aspect ratio, for the reasons that Colin and Sean have mentioned. (2) once applying the defined custom pixel aspect ratio, the file looks like in the right ratio, butĪfter I save the file, and open it from Picasa to view, it is not in the right ratio at all. Just stick with 1:1 and crop to 3:2 (or otherwise) and you will have no problems. The reason that your images were not looking correct in picassa is because most programs assume a 1:1 pixel aspect ratio *for all photographs*, or are simply not capable of reading pixel aspect ratio information in the first place. The image aspect ratio should really be set using the cropping tool only, unless there's very special circumstances.

Anything other than 1:1 will therefore skew/distort the image. To my knowledge, all digital cameras out today capture their images using a 1:1 pixel aspect ratio. This setting is mainly used for still images from video data, and other files that do not have square pixels.

What I like to do is to do some crop without bound with 3:2 ratio, then I adjust the file ratio using Pixel Aspect Ratio tool - which may twist a bit of the image, but not noticeable for most cases.I am usually never one to push absolutes, but in photography I would advise against ever using the "pixel aspect ratio" setting in photoshop. I can set a 3:2 ratio in the crop tool, but feel not so convenient.
