Image resizing...

[Denis]

How do you resize images? I know how to, but what method do you use?

I use a little program called PIXresizer, but I cant help noticing that my images do not appear as sharp when resized and posted on these forums. I always use the size of 1024 pixels on the longest edge..because I read that was the size they should be...wrong or right??

Is it better to resize in Lightroom, will that make a difference to the image quality?

The new camera takes a lot better image than the D5300, but seeing the few I have posted so far, I think something is letting down the result a tad!

I always export from Lightroom to the size I want.
My standard pre-set for web use is to fit 1024 x 768 and keep the file size to less than 250Kb.

I think it's the forum software itself that's causing the problems, I noticed if I posted the image as a url (linked to an external site) the image in the post was no where near as sharp unless you clicked on it, even uploading an image to the forum has the same effect. It never used to be like this until about 12-14 months or so ago. I post on other forums either by using direct links or uploading to the forum and never have the problem of images not looking as sharp as the original as I do when posting here.....

For landscape images I use 1400 pixels for the longest edge or 1033 pixels for portrait

In Photoshop CS6 I save all my forum-bound pics as JPEGS at 1200 mp on the longest size.... these suit then for using in emails too.

The originals are saved at 300, as taken in psd format after conversion from RAW.

Photoshop has a dedicated image sizing tool (Image/Image size).  In the drop down menu there is an option to re sample the image with several choices one of which is "Bicubic Sharper (Best for Reduction)".  It's the one I always use.  I'm not sure whether Lightroom has the same facility but you would think that ADOBE would use the same module in both Apps.  If it does, you could compare it with what you do at the moment.  However, as Geoff points out, the problem could be the Forum software.  Despite what I have described, I suffer some softening of some images but not all by any means and I have yet to discover why it is only some that are affected.

I didnt follow it up but for a while i used the save for web in photoshop, i did think it gave better results than save as, i had resized using bicubic sharpener

John- in LR when exporting/saving you have a drop down box with export location, etc and within that box is:  'Image Sizing' for web use I almost always use 1400px and at 90 ppi below that is 'output sharpening' I set to 'screen' and 'standard'. I find that works well for most websites but you could try the high setting.
