Website has been updated and the highlighting issue fixed.
Nice!
After looking around a little more, just a few things I've noticed. But before I go on: please don't take my comments the wrong way, I really like your site and your images!
Having said that, I'm not sure if the price tags are really a lot of help in finding new customers. At least for the "professional" sessions you're offering. Customers looking for private photos for themselves, family, friends or maybe for a job application might find this helpful. Companies looking for a set of photos for company profiles and such, will probably rather expect you to give them a quote. But that might as well be a german thing. I don't know.
Anyway, also for the other sections, having the "purchase"-button right there on the page might be a little too direct. I guess, for some potential customers getting pictures taken is a pretty private affair and that they'd like to get to know the photographer a little, before agreeing to step in front of the camera. For them it's not a business type service. All in all, I think I'd remove all the "buy now" features and underline a little your peoples skills and that everybody will be in good hands when you will take their pictures. Again, this might be a german thing.
Another nit picky thing, which might also be a technical issue, in your "professional headshot" section you announce the images as "crystal clear". At least on my system (FullHD 21.5" iMac with OS X 10.11.6 and Safari 11.1) the image you've chosen for this page seems a little soft, almost on the verge of being out of focus. I'm sure that's not the case with the original image, but the version on the page gives off that impression. So, maybe to underline the advertising idea of "crystal clear" a very slightly over sharpened image or a foto with a lot of resolvable details might better match with the text part. Another way is of course to come up with a different text.
Your writing style is drifting a little from business like concise information to a more easy going "just to let you know" kind of tone. So, in my opinion, this needs a little cleaning up to produce a more consistent impression overall.
Again, these are just things coming to my mind. If they're helpful, good. If you chose to ignore them, just as well. It's your site, your business and you'll know what you want. I'm in no position to tell you, you're wrong.
