I think you're both probably right. It's strange, I feel like when it comes time to put my portfolio together, I'm ruthlessly good at cutting it down to represent exactly what I want to shoot. However, when I'm trying to cut weddings down to blog, despite culling it again and again and again, I really struggle to hit the magic 25.
I think it comes down to this. In a portfolio of all your work, images have to stand alone. They're not supported by other parts of the same story. That's not the case with a wedding set for FM/blog. In that scenario all the images are self-referential and part of a whole. To that end, I find it hard to reduce a story down to beneath about 50 images. I can see that there may only be 10/20/30 standout/emergent images here, but for me, those 10/20/30 on their own are excessively incomplete because they don't tell the story of the day. One of the tenets of documentary photography is IMHO that images do not stand alone, they're part of a body of work and as such I find 25 simply too few in which to encapsulate the day.
Now, I may be wrong, but I think that's the root of why I often post more in the 40-50 range rather than 25-30. That said, I'm here to self-analyse to it's a useful convo to have!
