I would recommend any of the applications from this list at JPEGclub.org, which develops and maintains software for the Independent JPEG Group. They have a free piece of code called jpegtran which can do some basic transformations (like rotation) without re-encoding the image. Rotating images the "naive" way (rendering to a bitmap, reorienting the bitmap, ...

Such a thing is seemingly impossible with a traditional camera. I disagree with the premise of your question. People take well-exposed photos that include the sun with DSLR's all the time. If you're using a very wide angle lens outdoors, you may not be able to avoid having the sun in the frame. And yet, there are still plenty of blue sky images. Here's just ...

On Windows you can do it without any extra software in TWO operations. Select the files you want rotated in file Explorer, right click and do "rotate right" (or left) twice. It will be done losslessly if the image permits (eg, the dimensions are not "funny").

You could use ImageMagick with the rotate option: convert image.jpg -rotate 180 result.jpg You should be able to apply this command to multiple files, depending on your environment.

I found this simple command with just rewrite all your gopro pics: mogrify -distort barrel "0 0 -0.3" *.JPG More information about imagemagick command can be found on http://www.imagemagick.org/script/command-line-options.php#distort The method Barrel has the following arguments: A B C [ D [ X , Y ] ] An explanation how to set this four coefficients ...

There are several problems transforming the curvilinear perspective of the wide angle GoPro lens to a rectilinear one. The transformation stretches the image in certain areas and compresses it in others. This lowers the image quality as new pixels are created as approximations and interpolations from the information in the original image. There is also a ...

Import the existing photos from the card on computer and format the card on your new device. This is usual practice when you use old card on new device. BTW after each import also format the card, this can save you from some problems in the future (if only delete the images). And my humble advice will be not to use MicroSD cards on camera which support SD ...

No, the GoPro cannot be controlled over a USB connection. If the GoPro is plugged into a computer and switched on, it will go into USB mode. This lets you download photos and videos from the camera. But you cannot take photos or video in this mode. For the Hero3 or Hero3+ (or older models with a wifi Bacpac) they can be controlled over wifi. There are ...

If the result is a photograph, then it's photography. A video is just a sequence of still frames, and recording video is only 1 step up from the high speed drive modes (sports modes) on most cameras. The characteristics of the image are often quite different: Defects which wouldn't be visible in a moving video may become quite noticeable in stills ...

The way to solve this (IMO) is not to mess with the SD card, but to stop the Quik application from running in the background, monitoring every card you insert, and slowing down your computer. (I guess this kind of bloatware is useful for the tech-illiterate, but it bugs old-school people like me.) Click the "cog" near the top right of the Quik ...

$10 will get you a flash bracket that gives you a coldshoe or tripod thread to the right or left of your camera body. Even cheeper than that is some scrap steel, and a 1/4"-20 bolt.

Having been in your situation, I can safely say there are no perfect answers. I had an xTi (400D) and was looking to do underwater photography. I ended up deciding it was not worth it to get an underwater enclosure that cost more than the camera itself, so decided to wait until I could get a nicer camera to be worth it. In the interim, I went looking ...

None of the GoPro cameras can geotag photos. Because they don't have GPS built in, or any way of connecting to a separate device. The GoPro app does not support geotagging. So your aerial photos will not be geotagged. But you can geotag them afterwards. ie use a GPS device to record a tracklog, then sync this with the timestamps of the photos. There is a ...

You can use xnview on windows, which has some batch mode processings and also, for a simple rotation of images, have the option to rotate images based on the exif data. Select all the images (even the correctly oriented ones! It will know they are already well oriented), "rotate based on exif" and it will do it (without recalculating the jpg, so with no ...

No need for post processing. Relative to the camera, the motorcycle and rider are not moving (unless the rider waves the selfie-stick) so they are sharp. The background (clouds and landscape) are changing very little due to the distance, so they also look sharp. The road and nearby shoulder to move quickly relative to the camera, so are subject to motion ...

A more affordable alternative is to use the third-party anti fog inserts. I've bought a pack of FogFree for my old HERO2 and still use the same inserts almost 2 years later. They work the same as the GoPro branded ones but are much cheaper. Just "bake" them to dry and you can keep reusing them. The fridge/air-con trick never worked for me.

In an effort to make this question more about photography… Protip: Change the extension of the GoPro .THM files to .jpg you'll have viewable JPG image files.

I ended up contacting the manufacturer, who replied the same day and suggested trying to clean the lens with alcohol. And it worked! The 70% isopropyl rubbing alocohol dissolved what I now believe was residue from the glue of the protective sticker, instantly. Just using the microfiber without the alcohol wasn't enough to get rid of the glue. I'm ...

Assuming your photos are in JPEG format, I'm quite partial to JPEGCrops, a simple and free tool for lossless batch processing of images. You can crop to specific aspect ratios, and/or rotate.

FSViewer is a useful program that can do that. Open up the folder where the images are, select all that you want to rotate, hit F4 and go to the 'Batch Convert' tab in the window that opens up. Click 'Advanced Options' on the bottom right, go to the 'Rotate' tab. Check 'Flip / Rotate', then 'Rotate', then select '180' below and hit OK. Set where you want ...

May I suggest the batch mode of Irfanview, which only runs on Windows. Irfanview is also good for simple edits, but it is no GIMP. Once installed, select "File | Batch Conversion/Rename". From there it gets a bit tricky, you need to select all the files, you need to specify a destination folder, and you need to click on the Advanced Button to see Advanced ...

With windows you can mark all if them in the explorer then right click and choose rotate clockwise. Do this two times and your pictures are now rightly orientated.

After having tested Hero 5, the conclusion is that "No, Gopro is by no means fit for being compared with a DSLR". Although the video performance of Gopro is impressive, the bad low light performance due to the small sensor size of the camera is very tangible. Hero 5 has a very good dynamic range though and I can say that the dynamic range can be match to ...

30 frames per second for 30 seconds gives a need for 900 frames (30 * 30). Taking 2 seconds for each frame gives 1800 seconds (900 * 2) or 30 minutes (1800 / 60). You might have to add extra time for the exposure time of each shot unless that time is subtracted from the interval time. Or in other words, is it interval time from beginning of a shot to ...

Different tool, different purpose. A gopro is a so called action camera, designed to be easy to operate, not need attention during recording, easily mounted on your body or sporting equipment or on a vehicle, and resilient under harsh environmental conditions. Also, designed more towards the expectation to mostly record video, not still photos. Most ...

Are these holes appropriate for attaching a wrist strap? No. Those holes are for the bottom and side microphones. They are not meant to mount a strap to. Or is there another way? Sure. You can use one of the built-in folding mount fingers bosses on the bottom. Just fold one or both of the fingers down to loop the strap through the hole with a simple cow ...

After an actual test using my Hero 4 Black, I retract my comment above. Not only is this possible, it doesn't look half bad! I ran for two hours just out in the parking lot here in town - it's not even very dark here, and I was able to see stars moving in the resulting time-lapse! If you went someplace nice and dark, I think it might actually look pretty ...

There is one internal battery, which take care about the clock. Check please this web page, step 13, right image. If this battery is discharged (it is not rechargeable) lost of settings as clock is expected behavior. IMHO there is no way to change it by self, so my humble recommendation is to contact GoPro service

At first glance you could thread cable ties through the vent holes on the side of the helmet to make a loop (get them from the electrical section of any hardware store). From there you could use additional long cable ties or straps mounted to the curved camera base (that came with the camera) to pass through the previously made side of helmet loops. It ...
