If I were to work with Ken Sklute, and he were to say up front that he wants $8K for his service, which includes all images, then that's perfectly fine, considering his reputation and experience, which usually translates to pretty good images.
However, this is the typical scenario... we sign up for a wedding package at one of those bridal studios at Marina Square, Tanjong Pagar, or similar. We are told that the package includes photography, with a 20-30 page album, with no further details given. After the photography session, we are told that the package only includes 20-30 images, and all the other images will be destroyed. So, the 20-30 page album will only have 20-30 images, which is not nice (and they tell the bride this). They will work their way with the bride, to purchase more images, to form a montage-like album. The final bill for the photography alone will be $8-10k. The photographers involved are usually some no-name guy that shoots some Taiwanese-style over-exposed pictures... which is fine, but his services are not worth that much. However, the studios play a mind-game with the bride... and the groom has to pay (and sometimes tears are involved). Shameful tactics... but this is a very common modus operandi in Singapore.
We should educate our friends/family to avoid such chop-shops... and go for proper photographers. Their fees may appear higher up front, but the bill may be less, for higher quality work.
