    ok i know i should use ps for my photo editing , but still learning, and as some of you know , i have a problem shooting straight .
    I use picasa 2.6.0 for my photo editing , but one issue i have, is when i use the Straighten tool, it seams to downgrade image quality, i.e. make photo a bit blurred !
    Anyone else encountered this , is it a flaw in picasa , or is there a way of overcoming this iratating problem?

    The Piccasa straighten tool automatically results in a crop. This should only reduce the quality though where the picture is seriously askew :rolleyes:

    I seam to shoot many crooked shots -- maybe this is the problem !!!

    Does the ps straighten tool also result in similar quality reduction ?
    Think i need to start practicing/editing using PS instead -- thanks.

    Straightening is a misnomer. What it does is a rotation (clockwise or counter-clockwise) and then a crop so that the picture is square again and then a zoom so that its the same dimensions as it was before, leading to a small bit of blurring from the zoom, but on any decent photo I'd be really surprised if it was noticeable.... unless as stated above, its a very crooked shot...

    Can you give us an example? Like, the original shot and the straightened one?

    What size of pictures are you using it on?

    I think i have resolved issue, it seams you have to save the changes (i.e. the straighten ) before the quality is restored to original quality .

    When you view picture , then straighten , there appears a small loss of quality , but as i say when you save changes, and then review quality seams to get restored !.

    Glad it's sorted. Sometimes if an image is low quality in the first place (coupled with a low resolution) then rotating it by anything other than a multiple of 90 degrees will reduce the image quality.

    Photos been edited are around 800 k , which is pretty reasonable ! Doubt that size is an issue here !
