It's a real shame I have done a little research and it looks like BlueSLR has gone out of business. The website is not available or the support page through iTunes.

looks like there is a business opportunity there!

I have BlueSLR (Bluetooth device) and the Zesty cable for iPhone. I like the BlueSLR for the wireless capabilities when I am moving around allot. I use the Zesty cable when I am stationary as it uses less battery from phone and camera.

Both work equally well and I have had no issues with the devices, apps or camera getting the data from them.

D800 & D3s cameras and iPhone 4S iOS6. Both apps work fine with the new iPhone OS.

Here's the link to the Amazon GPs for NIkon if anyone is interested

http://www.amazon.co.uk/gp/product/B005D84SDO/ref=as_li_ss_tl?ie=UTF8&camp=1634&creative=19450&creativeASIN=B005D84SDO&linkCode=as2&tag=ifootpath-21

Interesting stuff. I take images for our walking directions website. We record a GPS track on the way round and I can import this into Lightroom 4. I can then manually place the images on the track. I would rather be able to record the GPS data directly to the photo as it would make it much easier. I am surprised that you can't connect the iphone to the camera (I have a NIkon D7000). Anyone heard of a way to do this.

i know you could take an iPhone picture and just copy the data but seems a bit long winded in the digital age. Love the D7000 as I have just updated from a D60.

there is an on camera GPS logger on Amazon.co.uk now for less than £40 so I might just buy that and forget the iphone option.

Our iPhoone app records a great track that so that bit is not the problem (app is called ifootpath if you are interested)

Would welcome any thoughts

There's an iPhone app called MotionX-GPS. I think it's free.

Set the app running when you leave home and it records your route (position recording interval automatically adjusts to suit your speed).
When you get home, stop the app and email the track file to yourself.
Import the track into Apple Aperture (presumably Lightroom is similar) and a single click tags all your photos from that trip with their GPS coordinates.

Brilliant. I especially like it because I take my phone with me everywhere.

The only possible problem is that GPS drains the phone battery a bit quicker - the battery might not last a full-day photoshoot.

This is looking great, an all in one device is very welcome when only one plug is available...

A news:

You might want to consider the Anza Borrego State Park east of San Diego.
700,000 acres of beautiful desert views.
Countless hiking or 4 wheel drive trails.
The Park extends from the eastern side of the Laguna Mountains down to below sea level
on the desert floor.
Spring bloom is remarkable but I'll take the desert any time of year.
A little farther east the Salton Sea offers some interesting sites.

Catalina Island would be a good place. You could take pics of the whales and dolphins to and from on the boat trip. Once on the island take the bus ride to the top of the mountain, incredible view.

Get up early and head out to Garnet Peak for the sunrise. Search Garnet peak on the sandiegoreader site for more information. Take your coffee and sit and wait. Fantastic site on a clear morning.

Your in for some visual treats then! Bring lots of memory cards haha I shot 52 GB when I traveled around there for two weeks back in the summer of 2010 :)Some of the best landscape photography I ever shot.

Thank you guys:) I'm college student, so I'm limited in budget (gas of course...) and can't leave too far away from Socal... But those places you guys mentioned are quite interesting. And Kanuck... Unfortunately I haven't been there yet but fortunately you've told me about it :) I think I'm gonna make plans to visit there. Thanks!!

Wow are you ever a lucky guy! My favourite places to shoot are in Nevada, California, Utah, and Arizona and I've traveled all over the World! Have you ever hit the highway and found some old broken down vehicles, old ghost towns, barns etc? They always make for great landscape shots especially with a nice dramatic sky with it. You've probably been to Joshua Tree National Park? I'm sure you have its quite the amazing location. The Wind Energy Farm in Palm Springs is spectacular at sunset and sunrise. The windmills make for great silhouttes except you have to mind the damn fencing. The Coachella Valley preserve, and Indian Canyons also have never disappointed.

Will you travel out of the SoCal region? I'm sure you have numerous times for your photography^^ Damn your lucky I'd love to retire in one of these aforementioned four states or at least have a vacation home.

Malibu Canyon, Cajon Pass, Point Dume is perfect this time of year (next month is the only time you can walk around the point because of the tide.)

I've probably went to most popular places in SoCal already. (i.e Yosemite) I want to get some recommendations for places that are not well known. I'm not a professional photographer, but I love to travel for photography. I like taking landscape and all things nature photos. I may bring my girlfriend alongside with me, so I would prefer places with great sight seeing... Anything would be great still. Thanks!

Also try this: *Link Removed*

It also has a free corresponding iphone/ipad app on the AppStore called blueSLR.

For now I'm going with the geo-tagging approach as shown in that youtube vid (thanks btw!). As I have a Garmin 62S as well as my iPhone/iPad. But eventually I reckon I'll go with the blueSLR solution or Foolography if they get an app on the AppStore.

Cheers.

Breaking news...

gps4cam is for sale in Apple’s App Store for only $1.99

I've been interested in geotagging for a while now but haven't found a way to use the GPS in my Nokia phone.

As gelu88 suggests, check out Foolography but it is a costly solution.

There's also Gisteq phototrackr plus, and di-GPS, which are somewhat less pricey.

check out foolography, it might be the perfect solution for you.

its an alternative to the GP-1 which is compromised of a tiny module that fits on the camera and connects to a bluetooth device.

This can either be a GPS logger or phone.

There are plenty of android phones that do this but i havn't used any iphone apps.

but this one might work: http://spench.net/drupal/software/iphone-gps

It sounds like a hardwired GPS unit to the camera is the only solution that will meet your needs and it will be the cheapest and simplest solution at the end of the day.

exactly, and that is not what I am looking for.
But thanks to everyone for the advices so far. I am actually more interested in solutions that work on the go. That is somehow connecting the iphone and Nikon via bluetooth or wifi over usb and then to use a tool similar to "DSLR Camera Remote Professional Edition" (maybe the best iphone app for Nikon users). If anyone has found a solution for this please post it here.
I am also concerned about the use of the GPS only because if you have to use online data with your iphone you're ultimately bankrupt as soon as you cross boarders.

The great thing about this method is that it works with any image from any camera.

Just make sure the clocks are synced and it will work just fine.

The disadvantage is that it requires an extra step in post, wheras "in camera" solutions don't.

take a look at this video:

If you are using Aperture 3, you can import a geotagged photo from your iPhone and add that data to the rest of a project shot with a non-GPS camera, using the "Places" feature.

I just found this one, it looks to do what you want.
