Crop tight to the 3 sisters, or the tower, upscale 8 times in PS, thats right, 8 times. Process and sharpen etc, down size and post. Same image, different NF effect, much more fun.

The reasoning behind this is photoshops bicubic resampling can have adverse effects. To me that's too much work so I normally down size in one swoop to the desired size (normally back the original size actually). Some may not be aware, but photoshop has specific resampling algorithms for upscaling and downscaling data;
Bicubic (best for smooth gradients) <--- default setting
Bicubic Smoother (best for englargement) <--- upscale
Bicubic Sharper (best for reduction) <--- downscale

Good information here where Bicubic sharper is used for both up and down scaling.

C'mon Mike, time for a Sidonio-reeeepro. Narrow Field?...with a Starfire comparo
Hey you guys are genius's now why didn't I think of that ...never in my 30 years of imaging have I EVER thought of that ....com'on guys, you really think me an idiot huh? I do that all the time, how do you think I got many of these

But thanks for the advice none the less

Mike
