Post Images here using the power of triangles

[Peter Ryan]

Just got it up on Google Earth. That's a long way out in a big ocean! Saw the airstrip. Think I saw the welcome mat just beside it?

What do folks do there? Is it predominantly fishing. It doesn't look particularly agricultural.

EDIT - That's another aspect of the power of this site to teach. Just googled and found this site. I am now much more informed about the planet I inhabit that I was 30 minutes ago.

Hi Donald,

It is a beautiful part of the world. All the islands make up the Torres Straights Island communities. Each island is separate community and they commute between the islands in small boats. Life is generally fishing and maintaining the village. A favorite catch for the locals are the turtles. Tourism is a contributor to many islands. There is a newspaper out of Thursday Island that covers the news throughout the area. I met the owner and editor on the trip to Cape York Peninsula not long back. The people are just lovely and have a great lifestyle. The problems are education and job opportunities for the young but each island has a school and they compete amongst themselves in sports, etc. Despite the warm water swimming is not recommended – there are large salt water crocodiles that are very aggressive.

I just Googled Murray Isl - what were you doing way out there. I have been to Thursday Isl and Hope Isl but that's a bit of a swim to Murray Isl?

Peter, I was doing a survey for a new power station facility. I have been to a few of the more remote islands in TI (as it is known locally). Murray is very interesting as it is an extinct volcano as you can see from the shape of nearby Dawar Is. Ion Idriess wrote "Drums of Mer" about the early days on Murray Is. Also below, still on the theme of triangles is the Anglican Church on the island. Thanks for the web page reference, Donald. I was not previously aware of it. Actually, if you Google Murray Island and turn on "photos" you will probably see my photos below which I uploaded to Panoramio some time ago.

Hi Grant,

That sounds like an good job

Now you have the engineer in me interested:-
What size?
What fuel would that use?
Are we talking little more than a large genny burning diesel, or something more industrial?

PM me, if too boring for here

Cheers,

Got no idea about the technical issues, Dave. A diesel generator in a big noisy shed that supplies enough power for about 200 families is about all I know. The more populated island (Thursday Island) has two wind generators but they only supply about 10% of the load (when they are working, that is)

Hah, being in the TV industry I am more used to the sort in a lorry or container that you can stand beside and not even be certain if it is running - that's how good the soundproofing is with all the doors and panels shut

Hi Pono and welcome to CiC. Do you have a first name; we tend to be a pit more personal around here?

My name is Shane but I've been going by my middle name, Kupono or Pono for short, since I was a wee young lad.

What Post Production software do you use?

Photoshop CS3 Extended

The colour also seems wrong but I do not know where you come from or where the shot was taken so I do not know if these colours are correct but they look very red to me.

I'm in Hawaii. I see the red that you're talking about.
Thanks for the help! Much appreciated.

Here's some more triangles:

Nice shot Kay. The diagonals break up the rectangular repition you can get within the frame of an image. To me it would have been a boring shot of he rail was square to the bottom of the image.

[purplehaze]

If that is what that thingy in the middle is. I was not good at geometry. Algebra was more my thing, but even that is gone now.



What do you think? Too dark? Too dull? Too square? C&C welcome.

Hi Janis,

Thanks for posting the image. I looked at this for some time before trying to answer your questions. I needed to decide what you were taking the image of and no doubt it is the shadows, in which case they need to stand out.

You asked the question “is this too dull” and I think that is it. Below I have taken your shot, moved the white point in a bit in Levels to make the white doors stand out and then applied a slight S-curve in Curves to add contrast. Finally I sharpened the image to give it punch. You have texture in the door and walls that needs to be shown bold with the shadows.

Of course there are many options and this gives you but one.

Could I be told what I could have done to better these triangles (images)

Hi Peter,

I was just playing with some options when you posted. The difference in sharpness between your version and mine is quite dramatic and I had already sharpened! (or thought I had). I am having some trouble translating what I read on this site about sharpening to the tools in Digital Photo Professional but I found a kind of manual on the Canon website that I am going to try to dig into tonight.

As far as the contrast goes, I think you're right that it needed boosting but I might have to play with it some more to find the level that pleases my eye.

I can't tell you how much I appreciate the commentary. This site is fantastic. Very stimulating. Stella does not share my enthusiasm, of course.

Hi Sujata and welcome to CiC.

I really do like #1 without any change. The column on the left draws me into the image and I then follow the powerful diagonal line and where it breaks I fall done the column but there is a rock at the bottom that forms a ‘visual full stop’, as I term it. My eye is not allowed out of the image so I follow the right hand column up again and back into the image. I then start exploring behind the columns. The colour of red and blue work well and the clouds add texture. I would be happy to have taken this image.

#2 has the same colour combination but the placement in the frame has cut off the bottom columns and structural base at the right. This allows my eye to fall out of the frame and I have to force myself back into the image. Standing below an image and looking up like this always gives rise to a vanishing point perspective where the image looks tilted backwards and inwards. This can be corrected in Photoshop but you do need to leave sufficient room around the sides of the image as part of the image (as much as 10%) can be cropped off in the adjustment. The corner column in front also needs to be straightened. This might correct with the perspective corrections to the sides but if not then you would need to straighten this.

How'd I do professor? Working on the RAW file in DPP, I moved the white point and increased contrast. (I don't know what I'm doing with curves, so I just moved the contrast slider). I could have increased it more without sacrificing much detail, but I liked it here. As you can see, I also played with the saturation. And then I sharpened. I think the result is much improved over my first image and I learned a whole bunch. Thanks! It's been an entertaining evening.

Hi Janis,

I think this is much better. I like the level of contrast you have achieved. This is where you need to apply the artistic touch to show the scene (i.e. light) either as you remembered it or how you wish to show it.

I do not know the program you are using but you are getting the idea. Well done.

The 'problem' between you working on DPP and all of us prattling on about levels and curves (from a Photoshop/GIMP perspective), is that DPP curves tool when you're on the RAW tab in edit mode, behaves very differently to the curves tool in the other packages. I did have something on it that explained how it did work and why it worked that way (maybe I read it on here). Apparently it meets the requirements of Japanese consumers who take a different approach to post-processing. And given that Canon is Japanese .....! Don't know what the truth of that is.

The Tone Curve Adjustment when using the RGB tab in Edit mode is more akin to what you would find in Adobe products, the GIMP etc.


So, there's a bit of translation and interpretation required to turn Adobe-speak into DPP-speak when it comes to discussing levels and curves.

ps -

When you say that you don't know what you're doing with curves, I don't know if that means that you do not know at all what to do with that line that runs from bottom left to top right across the background image of the histogram. So, apologies if this is teaching-granny-to-suck-eggs.

Using the RBG tab in DPP -

1. Click on the line about half way into the top right box in the Tone Curve Adjustment window and drag it up about 2 or 3mm.
2. Click on the line at about half-way in the bottom left box and drag it down about 2 or 3mm.

What's happened? - You've increased the contrast.

Play about with this. Click on the line to create a marked point but hold the mouse on it and slide the point up and down the line. See, you can adjust any of the tones depending on where on the line you've made the point.

And what you've created is the 'S curve' that everybody goes on about.

Again - apologies if all this was obvious to you previously.

Hey Peter,

Thanks a lot ... I feel like such a novice... I never ever thought in such depth you know... would just go and take a pic because I liked a certain frame that's it ... and besides I just started 3 months back for the first time in my life...

I am glad Im here... learning is better than self learning thanks a million bucks!

On top of everything else you are enriching my English! Love the expression; thanks.

Hi Donald,

I have played with curves once or twice in Aperture 3, but so much happens all at once that it is a little frightening. What was cool about tonight was that I finally went from tossing one ball in the air to juggling two or three without letting any of them hit the ground. So maybe now I will have the courage to try curves again.

The thing that about DPP that has me confused is the sharpening tool. Actually there are two: Sharpen and Unsharp mask. The Unsharp mask has three controls: Strength, Fineness and Threshold. I figured out that Fineness correlates to Radius but it took me a while to understand that the equivalent of a low radius is a high degree of fineness.
So I was setting Fineness to low numbers when I needed to set them to high. The other tool, Sharpen, has only one control. I don't understand why there are two tools and whether their effect is cumulative or not. DPP only zooms to 200% so I have to look really hard to see what is going on. (It doesn't help that I need new eyeglasses.)
The DPP tutorials on the Canon website don't cover the topic of sharpening.

It is my hope that Apple will get the ACR upgrade for my Canon S95 soon and I can do all this in Aperture, which lets me zoom to 1600% in the loupe so that I can see what is happening at the pixel level and the impact on the view at 100%, both at the same time.

So much to learn, but it is all coming much faster now, with your help.

[Donald]

Quick reply - Yes they are. So you're better sticking with one or the other (I suggest Unsharp Mask as it gives you more control, once you get to understand it).
