Best Resize settings

[yeoboy]

I have CS3 and Scott Selby`s book but am confused on how to resize Jpegs to around 10" x 8" to retain the most detail, And to the same size but for e-mailing.
My shots range from 3MB to 13MB, Any constructive tips please?

What is the original size of your JPGs? Would resizing to 10" x 8" make them bigger (up sampling) or smaller (down sampling)? This makes a difference.

Also, do you already have any image editing software?

Use the crop tool, you can set the size you wish to reset to. In the top bar right at the left hand side there may (I don't have CS3 so can't be sure) a tiny arrow next to the picture of the crop tool, click on this and it will give you various options, if not type the dimensions into the empty boxes next to it

See this recent thread as well as it may help

Create actions to take care of the re sizing.

I created 4 actions all told.

I save at full size for my records but I also save at:

800 x 600 both portrait and landscape orientation 150dpi - for posting here mainly and on my flickr

600 x 480 both portrait and landscape for ephotozine - 72dpi

This covers all my posting needs and email needs, the 800 x 600 should be fine for emailing as well.

The beauty is that when I've finished processing my pics I can then use automate/batch and then select the resize action I need, choose the folder to save in and its all done automatically in seconds.

You do realise that dpi (which really should be ppi but that's another story) settings for web/mail use is totally immaterial don't you....

 

[magicaxeman]

Yep, but they lower the file size all the same.. and yes my bad ppi.

The smaller number of pixels in the image lowers the filesize, not the PPI setting.

I hate to be contradictory but this isn't right. :bonk:

The following details are from 3 versions of the same pic. Dimensions 910 x 1213 pixels.

the image was saved at 50, 5000 and 500 ppi.

the file sizes are almost identical, and the small difference (300 bytes) is down to information in the file headers and not the image itself. Even that doesn't make a difference to the amount of space taken on the disc because of sector sizes. (Note size on disk is identical for all 3 versions).

Now, if you were to view these images on your monitor they'd be the same size because they're all still 910 x 1213 pixels and that's how much monitor space they'd take up viewed at 100%; if you printed at these resolutions though (assuming the printer would be capable) then the printed sizes would be:

@ 50 ppi 18.2" x 24.26"
@ 500 ppi 1.82" x 2.4"
@ 5000 ppi 0.18" x 0.24"

hope this makes sense....

To retain the most detail you are going to have to crop with the 2 of the borders of the crop tool right on the edge of the original image. Whether the crop limits are on the upper and lower or left and right edges of your image may depend on whether its in landscape or portrait in the first place.
So, select crop tool, set preset crop ratio of 8 x10 (portrait) or 10x8 (landscape). snap the edge of the crop area to an edge of your image, now enlarge the other edge/corner of the crop area to meet the opposite side of your image. Drag the crop left/right or up/down to get the best result you can. You are going to lose some of the original image obviously because it will not be in 10x8 ratio.(It will be 3:2 most likely)
Once you have done the crop, save it at maximum quality jpeg.

For emailing you dont need to worry about size as already mentioned. So simply resize your new image downwards to 1024x820(or 820 x 1024 for portrait) or 800x640(etc), then save as medium to high quality jpeg. Then email that.
