What's your requirement?
By figuring out your exact requirement in terms of expected output, you can begin narrowing the list of services that are available. Is it a wedding or a similar celebration party that you need to cover? What's the size of the party and venue? What altitude do you have in mind for the coverage? The level of demanded accuracy along with the coverage area and altitude matter a lot when choosing the perfect photography service for aerial shots. For weddings and parties, it is best to go with RC unmanned helicopter service by aerial photographers in Singapore. The same would also work if you needed to scout a site or get an aesthetically appealing coverage for a residential area or real estate project or other for commercial or promotional means. Whatever you requirement is, make sure that you have the basics worked out such as the required accuracy and details of output along with the average coverage parameter, etc.
What's your budget?
Hiring aerial photographers in Singapore who offer manned helicopter photography is surely going to cost you higher than Balloon or other means. The budget largely influences your output and also narrows the choices for you. If you are looking to shoot over a large scale real estate project that you wouldn't want to shell out a lot of money for getting a chopper with a photographer to fly over a project. But if you are shooting a lavish wedding celebration spread over a large area then you might want to invest in the manned helicopter option. If the celebration venue is fairly small and can be easily covered through RC unmanned helicopter then you wouldn't want to be bothered about accuracy and details either. So, fix a budget and an extension limit to accommodate any additional later on as per your requirement.
If the venue in a secluded location or is it a residential location with numerous neighbors? Even if you want to cover a commercial area that has entrepreneurial buildings for neighbor, you might want to consider the extent of noise your choice of aerial photography medium will produce. If you are shooting a wedding over a secluded cottage then manned helicopters would be okay and even if you are shooting a landscape then choose the chopper with a Singapore Aerial Photography expert will yield amazing results. But the same won't serve your needed if you are working in a dense area with commercial or residential buildings.
Choose the option that doesn't irate your neighbors and yields accurate and comprehensively detailed images without going overboard on your budget. Consider getting more than one camera to cover all angles if it is a live event you need the coverage for.
