Open TIFF file in Raw in stead of Develop profile

[JPW]

Is there a way to open a TIFF file in Raw Profile? 
TIFFs only open in Photo Develop Profile. I would like to find a way around this please

Not sure if I understood completely right what you mean. - However, TiFF files usually do open in the "Photo Persona". With a TIFF opened in the default "Photo Persona" just click top left on the "Develop Persona" toolbar button to transfer it into that RAW develop area.

Welcome to the Serif Affinity forums.

As v_kyr has said, once the TIFF is open in the Photo Persona you can switch to the Develop Persona if you want.

But I'm curious: you seem to view TIFFs opening into the Photo Persona as a problem. Why? They are not RAW files, and do not need RAW development.

Maybe the OP has one of those older EOS 1D(s) cams, those in the past used TIFF as their RAW file format (times before .cr2/.cr3).

Possible, I suppose.

But in that case, switching to the Develop Persona manually won't help, as far as I know.

Can't tell Walt, since I always just deal with NEFs (I'm Nikonian) and don't have any TIFF files which would behave like RAWs internally for try out.

Me, neither. But as RAW processing is significantly different from standard processing, if the files are RAW but Affinity is not recognizing them as RAW, I think the OP is simply out of luck. (But we're guessing, until JPW provides more information and context for the question.)

There's something odd about TIF files - if (e.g.) I rename a .jpg file to .dng  AP recognises the content and opens it in the Photo persona without any problem.  Much the same with other renames - AP can work out what the file really is and deals with it.  Try changing the extension on a TIF file and AP says the format isn't recognised.

Quote

TIFF is a flexible, adaptable file format for handling images and data within a single file, by including the header tags (size, definition, image-data arrangement, applied image compression) defining the image's geometry. A TIFF file, for example, can be a container holding JPEG (lossy) and PackBits (lossless) compressed images. A TIFF file also can include a vector-based clipping path (outlines, croppings, image frames). The ability to store image data in a lossless format makes a TIFF file a useful image archive, because, unlike standard JPEG files, a TIFF file using lossless compression (or none) may be edited and re-saved without losing image quality. This is not the case when using the TIFF as a container holding compressed JPEG. Other TIFF options are layers and pages.

Byte order

Every TIFF file begins with a two-byte indicator of byte order: "II" for little-endian (a.k.a. "Intel byte ordering", circa 1980)^[9] or "MM" for big-endian (a.k.a. "Motorola byte ordering", circa 1980)^[9] byte ordering. The next two-byte word contains the format version number, which has always been 42 for every version of TIFF (e.g., TIFF v5.0 and TIFF v6.0).^[10] All words, double words, etc., in the TIFF file are assumed to be in the indicated byte order. The TIFF 6.0 specification states that compliant TIFF readers must support both byte orders (II and MM); writers may use either.^[11]
