How can I reduce the 'posterize' effect going on in the clouds? Also any other HDR related insight. I'm using CS3. It's posted on my FB account, mainly because I don't know how to insert an image in this dialog box.

in the event that my last upload try failed, can someone please explain the process to me, i cannot believe it is this difficult to upload an image... on DPC no less!

This is not "uploading" an image, it is linking to an image hosted externally. The problem is that Facebook is not allowing us to see the image you're linking to. It's a Facebook issue, not a DPC issue.

The last attempt is not a "link" at all.

See above the "reply" field, 8 icons? The third from the right, a globe, is for "insert hyperlink". First go to facebook, get your picture up, right-click on the picture, and click "copy image location". Then go to DPC, make a post, click the globe icon, paste the image location, give it a title, and you should be good to go.

Facebook usually requires the viewer to be logged into facebook unless you've made the image public.

It's the public link you need to provide here.

there we go?

why don't you just upload the image to your portfolio here at DPC and insert the image here

That would be a very good reason for Brian to become a member!

You gotta parse the link. When you post, be sure to check the box "automatically parse URLs".

very nice!!! my attempts at HDR become over kill

OK, I can see the image now, it's a little small to analyze but I can see the blocking in the sky. It comes from trying to correct a totally blown-out sky, you're pushing too far and things are blocking up. The image you're trying to work with has no detail at all int he bright area of the sky, nothing you can do will bring it back. That's how it looks to me anyway. Unless, of course, you were tripod mounted, have 3-5 different exposures, and a program like Photomatix that can merge them into a single HDR image...

I like the image Brian. Got a great sense of desolation about it. The HDR is quite subtle and well done in places. Some of the sky is a bit too blown out though.
01/07/2010 09:18:47 PM · #16
I totally agree with it being blown out in the sky, that was the 'posterization' I was referring to, this is most certainly a first-try, not so bad really but I see there's a lot of prep work involved to make a truly nice HDR shot. I've got a new method to explore now! WOO HOO!

On your Profile page. I'm never quite sure whether to use first names or login names here so i'm not very consistent!

Like the others said the sky is a bit blown out. However with a few non traditional techniques you could fix it to look better, a little bit of work with paint brush and cloning tools you can add some cloud texture to the blown out areas to touch them up a little bit. Over all pretty nice photo. It is not over processed like so many of the HDR images I see lately.
01/07/2010 10:15:21 PM · #19
Another common technique to fix skies (or any other element in an HDR composite that's not to your liking) is to create a new PS doc with the HDR image as a layer and an image with the properly-exposed sky (most likely your lowest-EV-exposure in the bracket) as the background (or, more generally, a layer behind it). Mask the HDR image to reveal the properly-exposed image behind it. For example, using a soft- or medium-density brush to essentially blend the effect until you have a balance you like. You could also use a graduated mask or any number of other masking tricks to quickly deal with a large area.

Trey Ratcliff discusses this technique in detail in his HDR Tutorial, as part of his "master's touch" discussion. That tutorial, by the way, is a great HDR primer and worth a read if you're just starting out.

I use that process very often in predominately dark or black images, as well. Photomatix (my HDR tool of choice) and many other HDR processors "don't like black" -- they think it's just a really dark shadow and try to extract detail that simply isn't there. I just pop the HDR composite and one of my original exposures in PS as layers and mask out the "crazy black details," revealing the true black behind it.

Personally, I feel like the foreground of your image is a little too dark and the sky overpowers it. I'd love to see it with a graduated exposure layer or some degree of dodging/fill-light over the foreground to bring out more of the foreground elements and perhaps bring out details in some of the shadows on the bottom/left of the frame. That's just my personal thought, though -- if you like the sky/ground balance as-is, then I think it it's a very dramatic effect.

as well as your facebook page shares your last as well
01/08/2010 12:22:06 AM · #21
yeah, as soon as I asked where you got my name I remembered I have a profile here, and it's on my FB link I sent... I'm kinda thick sometimes :)

Anyway, yeah, this was a great thing for me to do today, it had been a quest of mine to figure out this HDR business but I just had other things going on... now I'm wishing I would have learned earlier... but it's never too late!

I would love to be a member but even $25 is something I have to keep track of these days. I wish there was a trust for photographers in financial hardship! One can wish right!?

This HDR stuff is a new interest of mine and you all can bet I'll post it up for some more crit action! Thanks!
