I am curious to know what methods you guys use for re sizing your images for upload here.

Do you use bicubic or bilinear methods? And what do you set in your resolution box? 72/96/180/300?

Do you do gradual resizing or in just one big chunk?

I have been asked a lot of questions about this recently and i think it would benefit the forum to have a thread where people can see what others do.

Please post your methods.

Chris

Resolution has no effect on resizing images. It only matters when printing (physical sizes depending on printing resolution).

I resize in one go, with standard settings in PS (Bicubic I believe)

Ed, i understand that but i have found that when sharpening the image they look different when the same sharpening settings are used but on diff resolution images.

For example two passes of 400% 0.2 0 on a 72 p/i image looks different to say a 96 p/i image. I am talking about on the screen too. Is this my paranoia or is it actually true?

Chris,

The DPI will have no impact on sharpening.

If a pic is 1024px wide it is 1024 wide whether at 72p/i, 96 p/i or any other measure.

xxp/i is totally irrelevant.. until the output medium comes into consideration

Sharpening is also very dependent on output medium... sharpening that works for a 1024 x 683 A.net image may be totally inappropriate for a 300dpi 16x20in print (almost certainly)

If your camera sends text messages, that could explain why your photos are rubbish!

Chris,

Thanks for your comments. I know all about sharpening for output. I am just finding that shots look different on my monitor when sharpened at different resolutions. To be honest it's probably my paranoia. LOL

Chris, where did all your photos on A.net go? Did you request for them to be removed or did you do something to deserve the removal? Just curious. See you in Orlando in a few weeks.

I find that re-sizing in steps yields better results. I reduce the width in steps of 500 pixels and add a bit of USM when I get to 2000, and sharpen again as needed when I reach 1200. I use bicubic resampling.

I was getting a lot of rejections for jaggies before I started resizing in steps.
