If the photo isn’t great then the portrait will suffer! Use these tips to get a great photo for your portrait:
Filters - do not use filters which alter the colours - it makes them look unnatural and hard to capture a true likeness.
Take a close up photo - so it’s possible to zoom in and see small details without it blurring.
Get closer to your pet if possible, rather than using the zoom in function!
Stay in focus - it shouldn’t be blurred or out of focus (portrait mode will put some of your pet out of focus - so avoid this if possible).
Use natural light - it’s the best way to achieve a colour likeness and be able to see all the lovely small details!
Try to avoid really strong sunlight though! You need a bright but overcast day ideally.
You can sit your pet inside next to a window, you want the sunlight to be on your pets face rather than behind them!
Send original photos - not downloaded from social media - as this reduces the image quality and it needs to be as high as possible!
If possible take the photo at the same level as your pet.
