There's just about nothing you can do to save solids and gradients from jpeg compression, you can just make it not as bad. PNG is the way to go.

You should give them tiff files. Yes - that is exactly what I say when people give me png.

I'm having trouble getting a smooth gradient. It looks fine and smooth in Photoshop but once saved as jpeg it looks like poo poo.
To be on the safe side you should probably dither the gradient or as pointed out above add some monochromatic noise. JPG is just one of the potential sources of banding. Printers can do that to your image too.

Zoom in to 400% and use the polygonal lasso pen tool, turn that into a layer mask...

Fixed that for you. Tweaking and refining an edge selection with paths is so much easier and more flexible than with lassos. I can't remember the last time I used a lasso for anything other than the very roughest work.

Eh, I think it depends on what you're used to. Once you get in the groove of add/remove/intersect selection, I find that the polygonal lasso works a lot better for pixel-level stuff. The pen is great if what you're selecting has a geometric curve, but when you have to start masking around things like leaves you're adding so many control points that you might as well be using the lasso in the first place. To each his own, though.

The option to tweak a path at the control points and save them for later for later wins in my book. I used to be a dedicated lasso user but not any more. Leaves, though, are a different matter. You're right - paths are not good for edges that fiddly. But in masking leaves I would be looking to pull a mask out of a channel before I ever thought of lassos.

Are there any good tutorials on masking and things related to it? I only have a very loose grip on the concepts of masking and what you can do with them.

Ideally I want to learn how to mask well, and the various things I can do with masking.

There are different ways of creating a mask and they seem to be all over the place in Photoshop. Here's a page that covers 4 of the tools:
http://www.lazymask.com/image-masking-tutorial.html

I'd definitely add the Select/Color Range menu item to that list as well. Once you've got a mask play around with all the commands in the Select menu which act on the mask.

I'm after a little advice on just what the hell I should do with this photo.
I took it a long while ago when I first got my DSLR and was quiet happy to have pulled off the shot, but now, looking back at it I'm kicking myself that I wasn't shooting in RAW :(
I have not idea what else I can do to it to really make it stand out. I'm also not too sure about the crop.
I'd love some advice and some feedback!

There's two.. slight variations..





I hope these aren't too massive.

Hmm, I kind of liked the black bird, in my mind it just gave it something different.
But here's how it looks without the black, just a quick spot heal. I quiet like it actually, but I'll need to re-crop on one version of it as the two orange birds look odd stuck in the center.

What do you think?

How the heck do I learn how to craft composite shots? I want to learn the photoshop side of some of Dave Hill's latest campaign shoots, and it's all just individual shots stitched together.

Rather than just say lasso + lots of layers + lots of masks, I want to learrrrrnn.

I've been trying to really put the time into post-processing recently to a point where I'm spending hours on certain photos. For the photo below I've separated the picture into 3 parts (bird, wood, background) and adjusted each separately. Is this what I should do? Does it make the photo look like a frankenstein image? Are there other adjustments that I should be making?

A human being that was given to fly

I am pretty unskilled with Photoshop since I have not played with it in years, but just got CS5 and decided to dive in head first.

I am also doing my first panorama, so I am a novice all around. I bumped up the greens around the town on the left hand side. They were pretty pale compared to the blue of the ocean. I am not sure if I should try to do anything with the inner rim of the volcano and trees inside it. They are pretty dark since the side I was standing on was casting quite the shadow.

How would I best go about making the inner edge stand out less?

Yeah-- Haven't had too much time to play with it yet though, but it doesn't appear to actually be any faster than 2.whatever. The most exciting thing for me was how well the noise reduction works, I probably won't even be using NoiseNinja again.

There are very few lens correction settings pre-built in though :(.

Photoshop CS5 seems to have all of my lenses covered, but I don't have anything too exotic. I hope they're accessing the same library.

And, by the way, in CS5/the new version of Raw or whatever, I'm a little skeeved out by the way Adobe seems to be handling the whole lens correction profiles thing. The community calibration tool (or whatever they're calling it) does not seem really exhaustive in terms of gathering lens data, and the interface to access submitted profiles makes my brain hurt. It's not really clear which (if any) profiles were created "professionally" by Adobe.

Yea, the lens correction feature was what I was most interested in seeing, but until someone creates a profile for the Tamron 17-50 it's essentially useless to me. Looks like someone finally got at least one Tamron lens in there so hopefully it'll happen soon.

This is a pretty amateur question so hopefully someone can help. In my career as a photographer I have never really had to worry about lighting, but I have been experimenting with more studio type of stuff lately and I cannot figure it out. There is a pretty harsh shadow around the head of this gentleman, and while I could probably fix it by placing the lights different that isn't really possible right now so I want to know about what other options I may have.

Actual question: Is there a way to select around his hair without it being super choppy and obvious?

brad industry

Move him away from the wall.


For selecting hair the way I prefer to do is work in the channels to make a mask with an Alpha channel. The basic idea is you choose a channel with high contrast between the background and subject (or you create one) which makes creating the selection much easier. Then you can convert the alpha channel to a selection.

I didn't watch this all the way through but seems like the same way I do it and covers a few different images:

A very carefully hand-painted layer mask. There are tools that will automate parts of it pretty well (mess with the refine edge tools for instance), but for the highest quality in a selection like that, you're going to want to be painting in each hair individually.

VVVV You're probably right, but I'm still unable to get things masked properly with the channels. If you can put up a basic tutorial on how you'd mask that out with channels -- especially given that it's monochrome -- I'd love to see it.

I think hand painted masks are actually worse than creatively using the channels. Besides, what the hell would you do if you had to do cutouts for a catalog or something? Paint hundreds of individual hair strands for hundreds of images?

So this is just a test really, trying to improve my touching up. Ignore the background and lovely masking trying to get that white, I was concentrating more on the face.

Thoughts on this? How does the skin look? Anything I'm missing that's obvious?

Been reading and watching alot of stuff on touching up, and thinking about it in steps has really helped me alot, I started with the basic stuff like exposure, contrast, then moved onto blemishes, shadows, skin etc.

My eyes were drawn to the dark spot next to the right side of her lip. That's the only flaw my amateur eyes noticed. It's not even a flaw, because it's in the original, but something about the touch up around it make it look almost unnatural.

Looks great! Did you shoot that against a wall or a backdrop? What color? Her right shoulder looks ever so slightly blown out, but I imagine that was part of trying to lighten up the rest of the photo. Doesn't look bad, just something I noticed.
