I cannot understand why diagonal lines appear on the blades of grass unless I view it at 100%. I have set resolution at 72ppi, is there something I am missing.

Im not seeing diagonal lines on the grass? Ive downloaded the large version, and viewd it at 100 and 2--% and see no diagonalsS I see on or two blades of grass that are actually diagonal, but you are obviously referring to something else.

can you be more specific, - is is low in the green area, is it higher at the top of the grasses, is it everywhere or in one place, - is is worse in one place?

Do you mean that if you view it SMALLER you see this?

If thats the case, very fine lines like blades of grass, if viewed small, - like a thumbnail can appear to have line running across, and this is likely got something to do with the fact you are seeing edges if individual pixels as the are displayed by different LCD elements, or if you have a CRT, scan lines crossing the blades? If you dont see it at 100, and nobody elsy does, thats likely the case, - and it will always be more obvious with any image with vertical or diagonal lines, and there nothing at all wrong. The image itself has the grass near diagonal, so might tend to look like diagonal lines?

OK, - I see what you mean, - and now that youve pointed this out, I see many areas where the grass has dropped out and been replaced by the blue background, and then the grass re appears.


From what I see, I think this is something being introdueced during compression.

First question is, - if you look at your original, do you see any issues? I will upload you shot with more areas Ive marked for you to check.

Assuming this is not in the original, and only in the reduced version, then theres one thing I can think of that you need to check when re sizing. At the bottom of the image size dialogue box (in me version) theres a drop down menu that allows you to chose the type of re sampling Photoshop should use. You need to make sure that Bi Cubic for Smoother Gradients is selected, - or if you have CS4 you may have an option called Bi Cubic Best for Reductions.


let me know which you use?


regards


Willie

At full resolution you will not see artefacts - lines. What happens in detailed areas is that the computer must reduce resolution to fit the image on the screen. Something must go, and that is some of the detail.

The image - OK, but no real focal point. You need a subject.

Willie,
I use Elements 8 and do have Bi Cubic for smoother selected.
The place where you say the grass dropped out and reappeared (where you have pointed to) that is actually A bouy floating in the lake just above the blade of grass.
If I look at the original the diagonals are much worse unless viewed at 100%.

Paul,
Thank you for your input,I guess that means I have to find out what size and resolution I have to use with this type of image. ( I don't have any problem if there are no contrasty thin lines in the image0.

OK, then it looks like it interaction between the size of the image and the display as mention by Paul, and in my first wild guess.

Did I mention I didnt see those particular diagonals you marked?

Youve done nothing wrong.

Don't play with resolution unless you have to - it is just to fit the display. Be very careful if you alter resolution that you don't save the new file over your old one or you will loose it. Either change it's name or save in a different folder.
