repair – How do I open the defective battery compartment of my Canon PowerShot SX100 IS?

Rushing – more later if it looks like it might be useful:

I have no experience with this particular camera.
But work according to general principles.

The slots on A and B are locking slots.
A pin penetrates the slot when the door is closed and moves into the locking position under the back of the hand when the door is moved sideways.
The red arrows at A indicate the path that the locking pin on the body would take to unlock it. The door moves in the opposite direction. BUT it is not obvious that there is a pin or tab at B in slot B. Slot A can snap into place under the edge of the housing at E. Or the door can be used in several models and the locks on A and B CANNOT be used.

A lock that is used is in
C with the current locomotive tab at D. This works with the Bendt-Lock arm at H. The arm at G with its shape indicated by a vent line is inserted into the space at C, and the Tipo slides under D when the The door is pushed into the locked position.

It is not obvious what happened in your case, but if this were my camera, I would consider the following.

  • Hold the camera down with your right hand and hit the top sharply with your left hand so that a muffled but solid impact occurs. Repeat several times. This has the effect of driving the batteries into the body and possibly removing an obstacle.

  • At H, insert a thin, stiff metal object along the line of the purple arrow. A nail file or a piece of spring steel (as used in some large wooden boxes as strapping when shipping). The goal is to work between door and hook at H and try to release the sliding effect of the lock.

  • Try to pry with a thin metal object between the body and the door (outside on the body side of A) to move the door in the unlocking direction. Tapping the camera gently but firmly during the experiment can help.

  • Use a drill with a diameter of approx. 6 mm (Really!) To drill into the door on the outside next to point D so that you can see and access the top of lock H WITHOUT DAMAGING IT. Once you are ONLY through the outside wall of the door, you can use a hand-held reamer or a larger drill (10 mm) to enlarge the hole without damaging the hook at H. This way you can determine if the hook is jammed. You can cut the edge around hook H without damaging H. IF this is the only lock, the door can be opened or partially opened without sliding.

    You can also use this hole at the edge of the hole to apply more force in the direction of being pushed open. As long as you don't damage hook G, everything you eat for dinner is marked on the door. The hole can be filled easily.

    Alsop, doors can be cheaply available on a used camera or as a spare part. If you attack the door gradually, you can open it at the appropriate time. If the actual camera is undamaged, it should be possible to install a new door after the problem has been identified and resolved if it is in the body.

Note that the two plastic bars at D should prevent the battery from being inserted with the opposite polarity. If someone succeeds in closing the door with a battery with the wrong polarity, it puts immense pressure on the door – it may only take a lot of force to push the door.

It is not obvious that the white material near G should have any effect. But I can be wrong.

added: Despite the counter option of the phantom downvoter, the above information can be helpful when opening

If I had your additional information about the lock button, I would try to insert lever objects (e.g. screwdriver tips) into the areas around the pinched button and apply extra force in the desired direction.

Compact Cameras – How can I easily take selfies with a Canon PowerShot SX720 HS?

This camera does not have a rotating screen, so you can not see the photo during shooting. You need to use common sense and guesswork to figure out how to point this out.

Hold it at arm's length and aim the lens straight at your face. Then press the button. Check the image on the screen and try again if the frame is off.

The camera is so small that you may be able to use a selfie stick and the camera's self-timer.

If you want to see the screen while framing the photo, you should get a mirror.

Powershot – Can I use the Canon Hacker Development Kit for a camera that does not have an official CHDK build?

Unless, you are a developer with experience in reverse engineering of firmware and ready to be one amount Due to time and effort, you can not use CHDK for your camera. As you can see on the CHDK developer page, the SX540 HS is black color coded. This means:

Black – There is neither original firmware nor firmware dump available

In other words, development of CHDK on the SX540 HS is not yet possible.

Why is the entire photo of my Canon PowerShot overexposed?

I use my camera since 2016. This is Canon PowerShot sx420. One month ago, one of my friends took my camera with me for a few photos. Now he brings this back to me. But the problem is, if I take a picture, it will be overexposed. But it looks so clean and perfect when I focus on a subject. However, after taking the photo, it turns completely white. What is the problem with my camera and what can I do now?

Color Correction – Why is the JPEG imported from my Canon Powershot G9X Mark II significantly different from the camera screen?

Look at the enclosed example pictures. I took them at 4:50 am and 3:50 am respectively. They were full of light on the Powershot camera's Live View display.

The pictures were taken as JPEG (yes, I should have taken that in RAW and found out the shadows later, but the screen told me the shadows were ok, so I did not bother with that). IrfanView claims that the color space is sRGB and there is no explicit color space setting in the camera. The laptop screen is IPS 8-bit 1920×1080 14 "(Lenovo Thinkpad L440) .I do not" import "the images into any application, just copy the files with Wiindows Explorer.The operating system is Windows 7 64-bit, fully legal, OEM preinstalled by Lenovo.

  • Look at the first picture. The shadows under the fuselage of the utility vehicle did not blend in with the color of the fuselage, which was gray and the detail well visible. On the PC screen, this area is really dark, almost black. Next, the trees in the background lose details in the shadows as well as on the PC.

  • Now look at the second picture. It's not as dramatic a change as the first one, but the whole picture on the camera screen is still brighter, with better visibility in darker areas and slightly better contrast, and the water is more vivid, bluer than gray. I like the water more than from the camera.

Hence the following questions.

  1. Is there a hidden conversion in the camera before the image is displayed on the Live View screen? Note that there is no RAW file for processing and viewing. The problem occurs with pure JPEG recordings.
  2. Is the camera screen equipped with a 10-bit panel or another color space?
  3. Is adjusting the photo settings for the next shot based on displaying the result of the previous shot in live view the right way to find the right settings for a specific shot?
  4. Can I see the same picture on the PC display and if so, how?

P.S. The supply ship is static at this point, so I can take the picture again while the discussion unfolds with the corrections made.

Does Canon Powershot SX520HS support tethering?

It's hard to be 100% sure (the lack of evidence is not necessarily a proof of absence), but apparently no, the SX520HS does not support tethering.

  1. It is not displayed in a list of cameras for which TetherTools offers solutions / support. The list of cameras that support tethering is not complete very wide.

  2. This reddit thread indicates that not even a remote trigger option is available, let alone tethering.

  3. Although this Canon community thread is not authorized by Canon itself, it says the same thing as the Reddit thread – there is no remote trigger available.

Due to the lack of a remote trigger (which might actually be enough for stop motion purposes) and the lack of support for TetherTools, I seriously doubt that the camera supports tethering.

Can I get a manual focus lens for my Canon PowerShot camera?

This lens is listed as compatible with Canon EOS-M cameras, which are interchangeable lens cameras. The PowerShot cameras do not have a replaceable lens. No, it is not compatible with your SX530.

I can not speak with the quality of the lens, but the lack of any reviews on Amazon says something … Like the fact that a simple Google search for "Brightin Star" shows … nothing.

Use only Canon DPP to correct the lens for my Powershot G7X Mark II and export RAW

I recently bought a Canon Powershot G7X Mark II. I use Linux and found that Darktable is a decent photo editor. My RAW images, however, have a distortion that darkens the corners and displays my photos as if I had a vignette.

I looked at the list of Lensfun cameras and the Mark II model is not yet supported.

Then I learned something about Canon DPP, which also includes the lens correction. This happens automatically when I open the photos in DPP.

Apart from the fact that DPP is only available on Windows, I can not figure out how to apply the lens correction to the RAW files and save it to another location that can be accessed on Linux.

I have saved some of these files in TIFF format to see if they are as editable as a RAW file. However, when I compare the edited files in the Darktable (RAW vs. TIFF), they differ significantly.
