Hi

does anyone know how to do the following in Affinity for iPad:

I’ve done a colour gradient using a palette but it’s not as good as the results Pix gets.

thanks

Hi @Raz_Mc,

I'm not entirely sure what you mean by this, as the tutorial you've linked seems to use the Curves Adjustment and no 'colour gradient', as far as I can see.

Equally, the Curves Adjustment will differ in algorithms and supported features between Affinity and Photoshop and therefore it's expected that the results may differ when using this tool in each app.

In particular the iPad Curves Adjustment still  lacks the features and range of settings available on the Curves Adjustment available in the desktop version. 🙁

Thanks for the replies. 
 

it’s annoying that the curves adjustment doesn’t allow you to change RGB values in a similar way to photoshop.  Would be great to have an option to do it wierd PS way or affinity way…

What's missing?

Hi Walt , it’s missing the colour picker. 

• Picker—click to activate the picker which allows you to drag on the image to modify the adjustment. An initial click-drag will firstly place a node on the curve in relation to the pixel selected and secondly modify the adjustment by dragging up (to lighten the image) or dragging down (to darken it). The curve graph will update accordingly.

Not exactly. You can touch the screen and drag up/down to place & adjust a node in the graph.

Yes Walt, that’s my point. There is NO colour picker. You cannot select a point (pixels) on the image itself. You have to guess where that region of the image may appear on the curve and then tap the curve. The picker sets the appropriate point on the curve for you. It’s been requested for ages but not been forthcoming.

No, you just tap the image. Your finger or Apple Pencil on the image is the color picker.

Thanks for persevering with this Walt. I can’t believe I never noticed that!!
All that’s really appears to be missing then, is the creation of a node point on the curve?

[walt.farrell]

No, it creates the node point, too. For example:

What about HSL adjustment? Am I missing something there too? On Desktop you can click to select colour spot on image. I try with pencil but adjustment always closes?

No, despite even the context help text says „Click or drag to set hue“ and shift/alt modifyer to add/subtract
