Image

Taken at Point Cook RAAF Base, the original is razor sharp, it is a pity that when i/we compress images for posting/emailing they lose their punch, or,,,,,am i doing something wrong?.

what do you mean by its lost its punch? what changed? can you show us some comparisons to illustrate what yuo mean? Do you mean some jpeg artifacting? or just that the image doesnt look good as it does at high res?

Darb, i mean it seems to lose the impact it does at high res,mainly the edge sharpness has gone.

presumeably you find this on all images that are reduced yes? part and parcel of lower resolution i would surmise.

maybe check the quality settings of the jpeg compression youre using when reducing?
but i dont think thats what youre talkigna bout

This may be a statment of the bleeding obvious but sharpening should be applied after the resize. Is that how you are doing it?

I love this shot. How was it taken? Are you in another aircraft? Is it a Pup?

Cheers

Thank's guy's, yes it is a Sopwith Pup (replica) and i took the shot whilst on the ground, the trick is to know how an aircraft looks at different flight attitudes, wait until it is flying near you doing this and fire away like mad,
luck helps a lot also.

Try an Unsharp Mask in Photoshop..as long as you don't over cook it and produce halo's you'll find it can look a lot sharper. You will always find that downsampling an image will soften it as Photoshop "anti-aliases" the edges in order to render it smaller than the original.

Don't forget that when you compress into jpeg, you will be bound to lose some of the detail or sharpness due to jpeg's compression algorithm. In the photo you provided, it still looks sweet though ;)

Whatever your on.............can I have some?

The shot is great. As previously mentioned you can't expect a hi-res post when posting a lo-res image (although the close up seagull shots someone posted recently made me think twice!)...I'm not sure how that was achieved. I think I'll post that question tomorrow.

It's a great shot with everything going for it. I'll do us both a favour and post a question on the awesome seagull in the morning.

I know what you mean, I encounter the same thing, but only just recently...My last few pics have been coming out blurry (thus the comments that it needs a little Unsharp Mask). I confess though I was unsharp masking, save, and then resizing and save. Are you supposed to Unsharp Mask twice?

Though this pic doesn't look that soft to me, looks pretty derned good.

It's a pretty cool shot, IMO. If I understand you correctly, you probably need to make some slight adjustments to contrast and sharpness, after you resize the image, to regain the "punch" of the original.

FWIW, after you resize an image, I think you need to at least use USM to restore sharpness. You can also do what is called a "local contrast" adjustment using USM first, (In Photoshop use USM at about 10-30, 50, 0) then do a normal, but light USM.
