HDR iPhone Camera Test – True HDR vs Pro HDR

With this week’s announcement that HDR filtering was coming to iOS devices in the next revision (4.1), I thought I’d try taking a photo of my living room with my iPhone 4 and True HDR:

Not horrible. But, here’s the same angle as snapped by Pro HDR:

The difference is like night and day (or, indoors and outdoors). “True” gave better balance between dark and lighter areas of a scene, but “Pro” produced a substantially more vibrant photo. I needed to try it again. Again, with default settings in True HDR:

And, again with Pro HDR:

It was subsequently suggested that I take an outdoor photograph (where True HDR would allegedly shine). So, I walked outside and snapped the two following images. Adjusting for the brightest spot of the composition:

And adjusting for the darkest spot in the composition:

Here’s how Pro HDR handled the pair:

And this is how True HDR fared with the same two sample images:

If I had a couple of bucks to spend again, I’d stick with Pro HDR. Not to say that it took perfect shots, but at least I’m given sliders to better adjust output.

I honestly wish I hadn’t purchased True HDR, as even in “enhanced” mode, it continuously left images looking flat and washed out, it always took longer to process, doesn’t have an adjustment mode, and also doesn’t allow you to save revisions of edits.

How Much is Gas in your Part of the World?

  • Avoid hard braking and accelerating (free) “Hurry up and wait” should not be a part of your normal driving lifestyle. Sure, there are times when you need to get somewhere in a hurry. But normally, you should give yourself enough time to get where you are going. So, take that time and you’ll find that you could save a whopping 20% on your fuel consumption.
  • Keep tires properly Inflated ($2 or less) I know it sounds like common sense to have the right amount of air pressure in your tires, but you would be surprised by the number of vehicles I work on that have too low or too high pressure in their tires. Make an investment of under two dollars, and buy a tire gauge. A properly inflated tire can increase fuel economy by 2-3%. A good rule is to check your tires every time you fill up, and before long trips. Be sure to check them before you’re on the road for too long, as heat caused by friction between your tires and the road causes the air to expand, and give a false reading. Also, go by the recommended tire pressure for your vehicle. This can be found either in your owner’s manual, or on a tire placard in the driver’s door.
  • Unless your vehicle calls for top grade gasoline, use the cheap stuff and supplement with gas treatment ($3 or less) Many people think that the more expensive grade of gasoline yields better fuel economy. While this might be true for some vehicles, there is a much more cost efficient way to get the same effect. The cost difference between regular and premium unleaded at my local station is around forty cents. This ends up being a difference of six dollars on an average fifteen gallon tank!! Use regular unleaded gas, and buy a bottle of gas treatment. This will give you back the fuel economy, while at the same time reducing the pollution that your car gives off in exhaust, protecting the environment.
  • Change your air ($5-15) and fuel filter($25) Imagine yourself being dehydrated, tying a scarf tightly around your neck, and running one mile. Now, take the scarf off, drink all the water you can, and do it again. No doubt that the second mile will be easier that the first. You have the oxygen and fluids that you body needs to perform. The same holds true for your car’s engine. Your car needs to breathe, and cannot do so with a dirty, clogged air filter. Replacing your dirty air filter can increase your fuel economy by up to 10%. And having a clean fuel filter isn’t just saving around 5%, it can also prevent a fuel pump going out. And if you have ever had that happen, you know how painful that can be.
  • Use FIC’s (fuel injection cleaners) every time you change your oil ($5) This tip kind of ties in with air and fuel filters, but I believe is important enough to get it’s own bullet. Fuel injectors can clog up over time, causing them to not get the proper air/fuel ratio for the best fuel economy. Using FIC’s is a cheap way to keep fuel injection systems clean and running smoothly. The difference between a clogged fuel injector and a clean one can be up to 6%.

“With these tips, you are able to save up to 44% or more!! At $3.00 per gallon average, and driving 15,000 miles a year… that’s over $800 a year in savings! If you follow my tips and spend about $50 during the year on preventative maintenance… you could end up with an extra $750 a year! Think of all the gadgets you could buy!”
