What am I doing wrong this time?


Recommended Posts

I'm trying to select the darker orange lines using Select Sampled Color. it's not cooperating.

Of course I adjusted the Tolerance slider and tried different models, and also I tried boosting the contrast first. No go.

EDIT: Apparently I didn't have the option to record mouse clicks on, but I clicked on them.

TIA

(This is a piece of a larger picture that I cut out and put on its own layer just to show what's going on.)

You seem to decrease the tolerance from 15 to 11. Why, if you want to pick more colours?

However, the tolerance in the menu/dialog selection seems to work differently than the Flood Select Tool:

Thanks, but the tolerance slider has nothing to do with it. If I click on the darker orange lines I want to select, the marching ants go to what seems like an arbitrary selection that’s somewhere else.

I’ve also tried selecting the mustardy color and moving the slider to exclude the darker orange lines, but no go.

Can you show a screen recording of that?

Walt, the one in my original post shows it if you zoom in.

If you can't see where I clicked initially, the second time I click shows pretty clearly that I'm aiming at one of the darker orange lines and it's not cooperating.

Sorry; I missed that one.

(But also, I don't think I ever have success trying to zoom in a video. How does one do that?)

Do you mean in-/decreasing the tolerance does not result in a selection marquee that includes the wanted colours/tints?

Can you mark some related spots/areas of "arbitrary selection" on a screenshot with the corresponding moment of your video? Possibly on the attached screenshot?

I see only 1 click in your video (crosshair cursor, slightly above the centre). It is at second 08. The selection marquee seems to include the darker orange and the major area of mid orange while it excludes a light orange (i.e. top right) and blue/gray/black areas for instance. Below a screenshot at 0:08 min.:

On my Mac I do not see any way to do that either. I can set it to play at my full screen size but it still does actually permit zooming in on any part of the video.

On mac a way would be using the zoom function via system preferences > accessibility. If setup it can be activated via keyboard shortcut.

The easiest way to see what I'm talking about is just to take a screenshot of the picture from thomaso's last post, open it in Affinity Photo (I'm using 2.5.2) and click here. I've also tried changing the color scheme of the whole snippet as well as increasing the contrast to try and get it to be more differentiated, but no go.

This spans multiple files that I made from the same source, and of course rasterizing it (even though it's a raster image to start with).

Just try clicking where the arrow is  and you'll see what I mean - at least I'd be surprised if you didn't!

The easiest way is to set up zooming in Accessibility, and then you hold control and slide the mouse "wheel" to zoom.

I have good eyes, but I use that feature all day long without thinking about it! Affinity Photo and I assume the other programs zooms in and out of the picture using Option + mouse wheel, but sometimes it's easier to see things on the interface if you zoom in on them.

I don't see your mentioned "arbitrary selection". The selection just appears to depend on the different colours at the cursor and thus includes less or more of the lighter orange in the upper right / bottom right area. (And, as expected, too, the marquee changes with different tolerance values.) – If you get different results at these two spots can you post corresponding screenshots?

thomaso, I want to select the lines like the one I pointed the light blue arrow at three posts up. They are a different color from everything else in this picture fragment.

Of course the tolerance slider adjusts the tolerance, but I think if you click on any of the colors I'm pointing at, you'll see it doesn't do it. You can also try selecting other colors in the hope of reversing the selection, but that doesn't work either. 

There's something Affinity Photo isn't happy about, so I'll just have to brush over them manually, but it would be nice if I could just use Select Sampled Color and bring them out more in one fell swoop.

Select Sampled Color is a fantastic feature in general, though - a perfect example of actual intelligence being far more useful than artificial intelligence. :)

That works but even if I zoom in on your video I cannot see where you are clicking so it isn't very helpful. The video also shudders & at one point jumps back a bit so I'm not sure of what is going on with it.

It might help if you could post an Affinity format file with just this part of the picture in it so we can try making the selection with the actual version of it instead of a frame of a video capture.

The set tolerance of 15% is perhaps too high, try 1%. Also I would try using the magic wand with a similar 1 or 2% tolerance.

I have never mastered color management, period, so I cannot help with that.

Yes, it is set too high, and at a low tolerance the Magic Wand is better - but it still isn't doing it (I tried that before too).

When I wrote above that tolerance has nothing to do with it, I just meant that it's not the issue. Of course it's the first thing you adjust when you use these features, because without that they wouldn't be any use!

The result is identical whether it's a new Affinity file or the screenshot, but sure.

FWIW, Select Sampled Color seems to behave as expected when I use it with your example file. How are you setting the sampled color, with the Color Picker or something else? Are you expecting it to be set with a click on the layer? If so, I do not think that is how it works.

That is exactly how it works: you click on the color with the tool and it selects it, you adjust the tolerance, then click Apply. And Bob's your uncle.

Using the Color Picker to sample the color first doesn't have any different effect.

So I'm not sure what you're expecting, but I expect it to work the way I've been using it for the past 2-1/2 years! :)

That is not how it works on my Mac -- IOW, it does not set the sampled color. That is how the magic wand tool works but for me I have to use a color picker to set the sampled color & make it frontmost (selected) in the Color panel. Then the tolerance sets how close to the exact picked color gets selected.

Just try it & see what you get.

Here's another thing to consider. (And my apologies if this has been mentioned already...)

Looking at the last image posted by @nickbatz, we can view it at this zoom level where we might want to sample the orange that I've pointed to:

image.png.786bd82a61e7fd7f31aaa2b46777c59b.png

But let's zoom in some more (I'm pointing to about the same spot):

image.png.b8de1e5fc02a94821bb00839192c9926.png

Exactly which pixel (and thus which color) might we have clicked on when it was zoomed out further?

I did try it!

If you set the sampled color with the Picker first, that color is what's selected when you first choose Select Sampled Color. But - on images other than this one - the color changes if you click somewhere else.

It's a good thought and no one mentioned it, but the selection still goes somewhere else if you select pixels that color - and I tried zooming in to the individual pixel level and clicking exactly the right color.

Who knows what's going on, but there's something about this example that stumps Select Sampled Color.

And the result is the same on the file I got this one from, in which the colors are blues/light blues instead of golds/oranges (yes, I steal from myself).

That happens for me on this one, too. As far as I can see, Select Sampled Color is working fine. But I've only tested on Windows.
