Where is the oil filter located on my 2010 V6 Camry

You would probably mean the oil pressure (or 'sender') unit. On the 1MZ alloy block V6 it is located on the front of the engine under the timing belt cover at about the level of the oil filter, below the alternator mounting. See here p140 (you don't need to do the large amount of disassembly shown in the diagram).

On the older 3VZ iron block engine it is on the outside of the block right next to the oil filter, near where the dipstick tube goes down.
.

Which is be hide the engine, on the top of the oil filter.

It is a V6? If so this is one of the very common oil leaks on Camry engines of that model, the others being the distributor shaft o-ring seal and on a V6, the rear bank cam cover gasket.

The oil filter spins onto an adapter which itself is bolted to the block. In time the o-ring seal to the block goes hard and leaks. It can be easily replaced.

Check oil sending unit.

The oil filters on the 2010 Camry product are no longher 'spin-on' filters. The new style of filter being used are the 'cartridge' type. The filter is in an aluminum cylinder, under the engine. Toyota recommends the use of a special tool to remove the cartridge cylinder. Also note that you need to use the exact oil specified for your car. If you do not, your variable valve timing will not work properly, and you check engine light will come on. If the car specifies to use full-synthetic, you should not use anything else.

Go to Google and enter "youtube toyota camry oil change." This is a fairly good video on how to address the oil change procedure that should be similar to your (and my) 2010 Camry LE, 2.5L; not exact, but you'll get the idea. Also, Google "Avalon oil change pdf" and click on the '05/'06 Avalon item to get a printable version that should also give help/hints for your 2010 2.5L. Now all we have to do is get permission from Toyota to waive the requirement for "only" 0W20 synthetic ($$$) in favor of either less expensive and more readily available 5W20 or 0W30 and extend the change interval from a very low 5000 miles to something more reasonable like 7500 miles or, better still, 10K! I've written to them to see what kind of answer they'll give, but am not hopeful of relief on that front. By the way, Lisle says their filter removal tool Pt. No. 54930 is the correct one and should be available from O'Reilly's Auto Parts; if not on shelf, should be orderable. Good Luck.

on the camry with the 2.4L inline 4, the oil filter is located just behind the plastic shield which extends below the front of the car... it will be on the passenger side, and is best removed with the variety of oil filter wrench which attaches to a ratchet (custom fit super graphite from shcuck's is the best I've found). I DO NOT recommend you use a strap type, or serrated jaw type wrench on this car, or you WILL have to remove the plastic shield, and waste a lot of time in the process.
On a camry equipped with the 3.0L V6, the oil filter is on the driver's side of the engine - mounted sideways. you SHOULD be able to get it through the driver's side wheel well. You WILL spill oil getting this one off - it's almost impossible not to, so be prepared for this. I'd personaly reccomend the type of wrench that attaches to a ratchet for this filter, but a strap or serated jaw type might work as well.
Hope this helps

The filter is under the engine. It is not a traditional "spin-on" oil filter. The filter is now a "cartridge-type", and is in an aluminum housing.

The oil filter is no longer a "spin-on" type filter. Toyota has changed to the "cartridge" type filters that are in a cylindrical housing on the engine. You need to remove the filter housing to access the cartridge. Make sure that you replace the o-rings that come out with the cartridge filter with the new ones supplied in the new filter box. To reset the light, follow these directions:

Turn the key ON, do not start the engine.

Look at the odometer, and verify that it displays "TRIP A". If it is on "ODO" or "Trip B", press the black stick next to the odometer to read "TRIP A".

Turn the key OFF.

Press in, and HOLD the black trip meter reset button, hold it IN.
DO not release it.

Turn the key ON, do not start the engine

Observe the Odometer display. You will see 5 dashes, then 4, then 3, then 2, then 1 dash, and finally, 5 zeros. Then, whatever number that was displayed on "TRIP A" will be re-displayed..

Now release the black trip meter reset stick.

This completes the reset procedure, and it will be back on in 5,000 miles, to remind you of you next oil change.

The 3.3 no longer has a "spin-on" filter. The filter is now a "cartridge-type", and is housed in a cricular aluminum housing under the engine.
