C&C ... well more advice really ...

Can you do me a small favour and have a look at the two Torres Del Paine panshots I have posted in my flickr ?

I was considering getting one of them printed on a large canvas either in three sections [thanks for the idea Sinead ] ... or as one image ...

I was going to do colour but when I was doing some photoshop tweaking of the images I selected the red channel to do masking and the mono image just popped out in all its dramatic finery ... so I'm not sure to do mono or colour now.


Any opinions ... please post them as comments in flickr ...


If you spot and flaws or other room for improvement let me know also ... e.g is the mono too dark ?

Also if you could recommend a place to do the printing, either online or in Dublin ? Do the printers generally perfer psd files or jpeg or ???


Here are the links to the two images -

Oh ... and these images were taken with a sureshot 400 (IXUS) ... here is the EOS 1d Mk III version on the Canon Japan site ... just for a laugh -

(shhhh ... don't tell the trolls )
Pish!!! ... mine is a far better composition ... who needs expensive camera kit!!!


Oh and here are the images themselves (I've just noted they may need to be straightened??) -

Wow, gorgeous picture!! I think some of the hilights are lost in the mono but that should be easily sorted out. Reminds me of a set of pics I took from the top of the highest road in Europe, all set to print them as a single huge landscape... It was only when I got them home and started stitching them together I noticed one was out of focus And not an end one either

That looks very familiar , did i see that before on TV ??

Anyway great shot , as i said last night , and colour all the way

Actually there is heavy Chromatic Abberation in the headland on the RHS ... the image is JPEG ... anyone know how to fix this ?

... or is it a cloning thing ...

Chromatic aberration as in fringing? I see some blue on the left hand side, and overall on the top where the sky meets the land a bit of that white fringe Guy pointed out that you get with oversharpening, but I'm not sure how much it would show up in a print.

There is a bit in the lens correction filter, but I'm not sure how effective it is. If you're going to print large, it's worth a bit of painstaking work, using channels just to tone it down if you think it's going to be noticeable. Try printing an A4 of the section out yourself at the same scale it'd be on the canvas, and have a look.

I think it's a shame to throw away the colour in this when it's the main thing that strikes you. The only problem is, if you want to try and get a bit more out of the shadows you're going to get some colour noise in there with it, you'd be able to push it farther in bw. It needs some test printing I think, before you can commit to a canvas print.

I love this shot mate and I think it would simply amazing as a canvas (whether its one or three pieces). In fact, I would love to have it myself if it comes out good when I open the studio!!

The mono defo looks a little dark in certain areas but as to which one to use, I am not sure as of yet!

Thanks Jools ... I posted it in the Cafe also ... getting some good critique in there ... thanks for that recommendation also ...

I prefer the colour version - the bw one seems quite dark. Maybe for the b/w one you could make 3 different layers with copies of the different channels then mask them together somehow to keep some of the darkness of the sky but brightness of the mountain range and foreground water areas ? Could be good to experiment with the different channels as layers using different opacities and blending modes - you might hit it lucky with that approach.

leinsterman

Hey Jools ... what do you mean by lens correction filter ?

bearing in mind the orignal images were shot as JPEG ... so I don't have the one in the RAW processor available ...

elven

If you go into filter menu there's a lens correction one in there, it has stuff to fix barrel distortion and perspective and all that. I thiiiiiink there's another tab that does the fringing stuff, too. As I say, there's no promise it'll do the job though.

latchiko

Yep, it's in filter -> distort -> lens correction (in CS). I use it quite a bit at the wide end of my 17-85mm. I find that it does a good job of getting rid of chromatic aberration. You'll see two slider in the dialog that deal with the fringing, can't think of the names of them off the top of my head, but one might be cyan and the other magenta or something similar. I've never actually tried it on a stitched panorama image, but I assume it will work.
It can be slow to load the dialog with large images so it will probably take an age to load up your panoramas!

leinsterman

... tried it and it did not work so well ... so I use a luminosity mask to protect the sky while I cloned in the edge of the dark headland to get rid of the fringes ... what do you think ? can you spot where I did it ?

latchiko

Another option is to use a hue/saturation adjustment layer and decrease the saturation on the cyan/magenta (depending on your fringing). Invert the mask and then paint on the adjustment in the edges it is required in.

Removing it on the originals then restitching might be faster and get a better result, especially if the lens correction dialog is trying to interpret the image as being a single frame.

The mono shot looks incredibly dark to mine eye.

... yeah ... I printed it and it looks even darker ... so I've got some work to do ...
