Affinity Photo v1 Ipad - How To Reverse MetaData On Affinity Photo?

[Mainecoon364]

I’ve learned that when I shoot in RAW mode and apply some settings like

 

A) Creative Filters (Toy Camera, Sepia, Black & White etc.

B) Sharpness

C) Picture Styles (Portrait, Architecture etc.)

D) Custom White Balance 

 

on the camera.

 

These are saved as Metadata.

 

Which means these can be reversed or disabled on apps like (Photoshop, Affinity Photo etc.)

 

And does NOT effect the original photo data. 

 

So let’s say I chose Toy Camera on Canon and shot.

 

So how do I reverse, disable this setting on Affinity Photo Ipad v1?

Affinity does not make use of those settings at all. When you Open the RAW image, you get only the RAW image sensor data, not the effects that are applied to the JPG version of the image that your camera can also record. So there's nothing to "reverse" or disable, as long as you Open the RAW version of the image, not the JPG version. 

[NotMyFault]

Some of those effects are only possible to save as jpeg, and not as RAW file. You cannot reverse those effects if you only have the jpg file.

[walt.farrell]

It's also important to make sure that you are saving from your camera as RAW or as RAW + JPG, and that when you edit the photos on your iPad you are getting the RAW version of the image. If the image opens into the Photo Persona in Affinity Photo, then you're editing the JPG version. If it opens into the Develop Persona, then you successfully got the RAW version of the file, and none of those effects are present.

I was already talking about RAW Images.

 

So how can I open a photo as RAW Image on Affinity Photo and reverse those effects?

 

Is It possible on Affinity Photo?, Affinity Photo Ipad, v2s or etc.?

 

Is It possible on Photoshop?

 

 

[NotMyFault]

Affinity Photo does ignore all these Settings A, B, C except D white balance. So no need to reverse anything in the first place.

Wrt to white balance you can adjust the WB to any value you want using the sliders in develop Persona.

There is no „native“ value. It is always calculated from the actual image, the Camera stores the value calculated.

[Mainecoon364]

So do I have to do White Balance again from scratch on Affinity Photo?

 

Since I did on the Camera is disabled. (Shooting the Grey card etc.)

 

 

[NotMyFault]

White balance is used to adjust the colors in the RAW files in a way that it best matches the human perspective of the scene, and areas who are white (in normal lighting) will look white despite the actual lighting lead to yellowing or otherwise non-white result.
The Camera always calculates a white balance preset based on the settings you have chosen when taking the image, and stores this value in the RAW metadata.

Affinity uses the value stored in the RAW file by default.

If you don’t like the result, you can set a different white balance manually in the adjustments, or using the white balance tool.

The image will have a white balance setting even if you choose a monochrome picture style, as the RAW data is still having all colors.

Thank you very much for the answers.

Agree with all above but remember if viewing on a monitor, that each monitor can be calibrated to different colour temperature, and that could affect how the image appears on that monitor, not all monitors will display the same even while displaying the same file.

Different monitor technologies have different abilities to display colour, this can be see within the family of Apple products.

So regardless of how you setup or save your colour balance it may appear different on a different device, but at least you can standardize how all your own images appear on your own device.

If you use calibrated displays (to a specific color model and profile), you can’t adjust display white balance / color temperature (of the display) any more or you will break calibration. White point are essential parameters of color profiles.

So a image will look identical (within the bounds of accuracy) on all calibrated displays who cover the color gamut of the image.

This assumes the display will cover the minimum requirements to brightness, color space, color profile chosen.

Apple give no mechanism to calibrate an iPad, so unless you know how the iPad is calibrated, no way to match a calibrated monitor with the iPad.

[NotMyFault]

Seems you are randomly switching topics. Do we talk about

• displays allowing to adjust color temperature (the link you provided earlier), (breaking calibration!),
• or iPad displays not allowing calibration (but you can always check via test images how good the display is),
• or iPad Pro model which allow calibration?

https://support.apple.com/en-us/111792

 

The iPad displays are quite good give a great rendering when you use the recommended settings (brightness, True Tone).

look for delta-E for some models below:

https://www.tomsguide.com/tablets/ipads/ipad-pro-2024-and-ipad-air-2024-tested-heres-how-apples-m4-silicon-performs

those Delta-E values in the range of 0.2 to 0.3 are „not noticeable“, so no need for calibration.

Well actually as I understand it, the original OP was wanting to match the colour profile he manually calibrated his camera to and the output he was seeing on another device, iPad included. He wanted them to be the same, I was only suggesting that matching his in camera colour balance to a different device isnt a simple task as there are many parameters that can influence the colour seen on another device.

Just checked my iPad Pro, old one 2017, no ability to adjust white balance.

@Mainecoon364 You might look at this

I’m assuming you took pictures (not with Apple device) using a gray card.

As this post suggests you can create a new colour balance profile from your gray card image then save it as a preset. Then can apply that preset to all photos using that gray card. While not using your camera image settings at least you’re using the gray card to set the white balance standard as you would in your camera.

The OP had one specific question:

So let’s say I chose Toy Camera on Canon and shot.

So how do I reverse, disable this setting on Affinity Photo Ipad v1?

And the simple answer is: you can’t reverse the effect because the Camera creates a jpeg (not a RAW) when using this effect.

Full disclose: I own/owned 3 Canon Cameras offering such „Creative effects“. And the user manual explains that the effect is „burned in“ and not saved as metadata (unlike white balance).

This thread is about reversing settings for picture profiles or filter effects made in Camara and if and how you cannreverse them in Apps like Affinity Photo.

A discussion about displays allowing white balance is simply off topic and not relevant for the original question. 
Even when using totally wrong display settings, you will normally see a difference when adjusting white balance in Photo, and you can reverse metadata settings but not filter effects burned into a jpeg.

Thank you very much for the answers again.

 

NotMyFault got my question right.
