Thank you much appreciated

Oval Thank you there’s no visable sign of quality loss.But our brains a renounded for no colour memory. my point was to try and get an answer for any one new to affinity below. 1. If you output a file from raw in your raw processing software full resolution you have a 150mb Tiff file. This is the Same in Capture one and Lightroom and Ps .why are all these massive companies doing it this way?? Is it so the tiff is lossless. There must be a reason why there’s so much data in the file. 2. Why the same file that’s been used output to tiff 150mb Is taken into affinity and saved only 40mb file. you can shout Lossless all you want From a different tiff compression but it still makes me nervous on a Tiff as it normally a standard size through out the other most popular programs. For the the benefit of Photogaphers out there that who need to be comfortable with this massive loss of data in there Tiff file. Without just ditching affinity as it’s not what they are used to. This seems to be the answer. Afinity saves down your tiff file with compression that is Lossless. More so than Photoshop. ( yes we all googled it.) Why are the others staying away from this method and retaining the 150mb file and not 40mb that Afinty puts out. The algorithms was made years ago. Would be great if this was explained and accessible from Affinity web site so it gets this program where it deserves to be but I’m afraid I spoke to lots of photographers who just bin it because there’s no time to look in depth of why it does this. most people are aware of what compression means on a file and google it once. That don’t spend any more time on Getting a masters in computer science. So I think it’s important that we explain the reason why affinity is so different from photoshop. At saving down at such low megabytes. the answer I’m getting from all my assistant photographers who try infinity tried it. like it. Binned it as it’s so different from photoshop. Come on let’s explain this. So they don’t bin it. Some tech guy must have a logical answer.. I’m still nervous

Thanks Alfred that’s helpful. Was worried I had some auto sizing turned on in the program. Take a while to get used to a new different program. I hope you understand my concerns . Much appreciated the info

Thanks John Thats an answer i kind off understand. Camera shoots Raw normally processed in capture one as a 8 bit tiff sized for use. i was asking for the reason why its so small that make me nervous. So i only used to a tiff being the same size when saved in photoshop. So the Tiff is compressed in affinity and not photoshop is that correct? . Is it just a different way of doing things in Affinity. different code. Was just a bit of a shock after being used to photoshop. Would like to be assured there no loss. i'm working with lots of different images each day not just black or white so i look at the file sizes a lot and notice how much they change. So My Question was Why i need not worry compared to photo shop. Below is the reason i ask. As the big Lossy is not enough for me . TIFF: TIFF format is the standard for most commercial and professional printing needs. We use the uncompressed TIFF format meaning that no image data is lost after scanning. ... JPEG compression does discard some image data based on the amount of compression used. No Compression: Our TIFF files do not get compressed.

Thanks for your speedy response. Much appreciated your answer . Yes i know resolution has nothing to do with size. Yes i know how Jpeg works and i always shoot Raw and LZW (thats why photo shop asks). As i said above i am working with a Tiff ( not jpeg as above) to retouch in affinity instead of photoshop. Should i be worried if i have a 150mb file off my camera full res then i open in photoshop retouch and theres hardly any change in size when flattened and saved .( on Mac ) When i do the same in infinity photo it saves it at 40mb instead of 150mb . Sorry but were is all the info going. Yes i should be worried? The Answer is Yes Very. Does it just throw all the info away.? if you look at image size in photoshop it explains all dimensions and dpi and physical size. thats all i want for print not web. ( don't want to hope for the best and think its just magic) i am sure there is a lot of people wanting to swap over to infinity but have these little niggle's of how it work and are just not used to it. Thats my question that will determine if i still use this program or go back to photoshop. Which is a shame because its great but makes me nervous of putting out a file that has half the information. i hope you see my point as this is very important to anyone that will use at a professional level. Never come across this before and all i want is a rational explanation. So please can you answer Why this happens. Im baffled with perhaps what i am used to. Would be much appreciated. Please help me and my team cross over to using this program. Just don't want another post that doesn't get answers again.

Thanks for reply. Its a bit hard to explain but i know what my mega pixel is on my camera and its saying 14 megapixel its not my camera is 50 megapixel large format. i produce a file in photoshop retouch and save nothing changes including the size of the file . i do the same in infinity and it has a lower Megabytes. but same pixels dimension. There no compression as i'm outputting to Tiff so size would not be affected. I have use lots of different programs that output what i tell it without no downsizing. PS C1 Lr Phocus and Sinar .Please can you help me with an answer to this. Would like to get a professional answer why a tiff becomes lower megabytes when saved and photoshop keeps the same size. I Output every day to exact sizes in all formats and different compression so i know in my head what a A4 Tiff at 300dpi i file size is. Please someone help ??

I’m new to using afininty from ps cs. Please can someone tell me why my megabytes is lowered from export and save . I do not want to change the size of my image. I find it very frustrating that I cannot see its telling me my resolution is 14mb top left when I’m using a 50mb camera. Love the program but will ditch it if it’s downsizing auto. How do I turn off so my original stays the same size. The pixels do not change just the megabytes is halfed.
