BLUE SKYS - Digital Noise in Digital SLRs

so new to that, Im not really sure how to lassoo / select everything except the rider and bike?

is it possible to somehow easily just select every area except the bike and rider - eg like everything that blue color or something?

the sky is gonna be a large area - lots of these pix are a bunch of blue sky by the way, with a bike and rider somewhere in it (some zoomed in on the original, some originals zoomed further out) - which is also partly why I wondered if it may be possible to somehow just put in a whole new non-grainy sky from a slide or digital 100 ISO?

thanks a lot

Ok, lasso bike and rider-then

Select>Inverse(This selects everything except bike and rider)

Filter>Smart Blur- then Select>Deselect

Hey Ken

just tried it
on laptop with laptop mouse

used magnetic lassoo (couldnt work the others)

smart blur settings - medium quality, mode normal, radius 3, threshold 25

sound about right???

it looks okay on the screen, and maybe even fine!

cool, if its that easy!?!

im crappy with the lasso thingy but, pretty rough around the edges, guess it takes some skill, but it may not matter as much with this approach

looking very promising, will see how some tests print

Cool, TA

Hey Ken

another question, u been so helpful, hope u dont mind

- just read u can adjust certain in-camera and other settings in raw - like ISO, luminance, etc etc?

- do u think it may make much difference after the fact in this case?
(as sky noise speckle/blotching here was very high)

- have Canon DPP for raw, but the Raw functions seems a bit limited to me, and maybe other raw softwares can adjust other settings/camera settings? might this be really useful for blue skys do u think?

- with my Photoshop CS, dont seem to have the Raw codec / Raw option, and upload a version that will actually work with CS (1) [as its not there/wont work/wont upload into CS]

any more thoughts / ideas on that?

anyone know where I might find a workable version of the old raw codec software thingy that will actually upload into and work in the original photoshop CS (seems Adobe one doesnt work for my CS/wont upload into PS so that it actually works ......)

Noise control Works well, doesn't it? ( I forgot to add to rate the feathering for lasso at 30 pixels for a smooth transition)


As for your question about RAW-sorry, I never use RAW-never found the need to-but Photoshop CS doesn't have the RAW facility.

Hey Ken


yeah, seems like it really does

powerful stuff if u know what ur doing

thanks for the extra tip too

cant wait to get hold of lightroom and CS4


ok - no raw option for CS (1) - ahaha, well that could explain why it didnt work/upload into CS then

good to know


Thanks so much for all the help Ken, and the other peeps too

will let you know how some test photos print out - fingers crossed

I just use the photoshop plugin 'noiseware'.

I find it usually works great for clearing up noisy skies if you turn the strength of it up. It can blur out the details in the rest of the shot a bit but nothing a mask won't fix easily.
