Thank you for explaining everything so clearly! Definitely the best channel :)

[CarneyAsada]

Thank you for this, it seems to be exactly what I was looking for! Reading about how to do it online is confusing, so it’s great to be able to watch you do it and make sense of what is going on!

I will be applying this to turn one photo into 12 photos for an Instagram grid. Is there anything I should consider about this video with that in mind?
