The size settings actually set two different things for any JPEG images taken by the camera: the resolution of the image being taken (the # x # size), and the quality setting for the JPEG compression for the image. The L, M, and S sizes vary individually by the camera, but the numbers at the top in the blue bar tell you the pixel dimensions. So, in this ...

That's how it's meant to look. Refer the manual from Canon's website, page 23: Refer also p36: the top LCD should be the same.

5472 × 3648 pixels at quality=81 One of the ways to check: exiftool -b -previewimage -w jpg canonraw.cr2 This will extract the preview from canonraw.cr2 file and write it next to the canonraw.cr2 file as canonraw.jpg. Next, run imagemagick/identify over the canonraw.jpg like this: identify -verbose canonraw.jpg | grep 'Quality\|Geometry' exiftool: ...

If your camera supported custom tone curves, you'd be able to get a similar result to this straight out of camera. Unfortunately, yours doesn't, so your only option is post-processing. There are many ways one would get this effect in post. Basic levels adjustment - put the black point output as a value above 0 using a levels control or similar in ...

You want to contact Sigma and find out if they'll still rechip the lens. Given the age of the lens and the fact that you're not the original owner, they may not be able to rechip it, or might charge for it, but it's worth a shot--the worst they can do is say no. Third party lens makers typically reverse engineer the electronic communication between the ...

What you call originals are the preview jpegs created in-camera and attached to the raw file. These are the images that will have Auto Lighting Optimizer applied. Lightroom displays these preview thumbnails while it is waiting for your computer to generate a high quality preview of the raw file based on the current Lr settings. Once your computer has ...

I was just wondering is it meant to be there or is it manufacturing error? It's definitely intentional -- it's the same in the viewfinder and on the top LCD on my Canon 6D. However, the icon on the Battery Info page on the main screen lacks the open spot. My educated guess is that the hole in the battery icon provides access for the conductors that ...

The 50mm f/2.5 Compact Macro lens is not a "true" macro lens. It does not magnify 1:1 (i.e., 1:1 means that the size of the image on the sensor is the same as the actual size of the object); it only magnifies 1:2.5. So, it doesn't let you get as close as a true macro lens like the EF 100mm f/2.8L IS USM Macro. In addition, the design's a lot older. It was ...

Even though the files from your new 7DII are in the .cr2 format, the data in a raw file is always sensor specific. That is, each different sensor design must be demosaiced/converted differently to get the same standardized results. Lr 3 is a while back. The latest version of Adobe Camera Raw (which is used by Lr to demosaic raw files) was released a long ...

Your best would be to find a PictureStyle that fits your needs. There's a QuickGuide to Picture Style Settings and Customization pdf that will get you started. It is from the Canon Digital Learning Center.(http://usa.canon.com/dlc) I'd like to quote from this article that's about the adjsutments specific to your camera in the following: Find the Picture ...

It seems like you have mirror lockup enabled. The first full press of the shutter button will cause the mirror to move up (just as it does before taking a normal photo using the viewfinder) but the shutter will not be opened. A second full press of the shutter button will activate the shutter to take the photo. If the shutter is not pressed again for 30 ...

One could shoot an entire wedding with a 70-200mm f/2.8 IS, a 50mm f/1.4, or a 24-70mm f/2.8. Beyond that, the answer is... it depends. To me, your list is all over the place, and it sounds like you would be best to work with the equipment you currently have and gain an understanding of photography and your equipment needs before you try to buy more stuff. ...

Sorry, there is no way to make older studio strobes automatic, or even semi-automatic. You must use Manual mode for every photo. 1/200 is the max sync speed on your camera, but when using radio triggers, there is sometimes a very slight delay introduced. To be safe start with with 1/160 f/8 ISO 100. You can then adjust the power of the strobes to get the ...

From what I've researched the only real difference is how close you have to be to your object to take the pictures. It's true that the 100mm lens lets you shoot from twice the distance as the 50mm lens and get a similar composition. That's because the angle of view for a 50mm lens is twice that of a 100mm lens. But the composition won't be exactly the ...

Another difference is that the 50mm isn't a true macro lens since it doesn't let you reach a 1:1 scale. The 100mm can also be used as a short telephoto but otherwise, you might be better off getting a Canon EF-s 60mm f2.8.

Welcome to the Photoshop tax on new cameras. :) Essentially, RAW is not an acronym or a file format or a standard. It's a raw data dump from the sensor/processor. And it's different for every single camera model. The CR2 files from your 7DMkII are different from the CR2 files of your 7D. And since Adobe has no time travel capability, they can only ...

Yes, and no. :D The 430EXII has no wireless eTTL master capability, just like your T2i, it cannot be used as a master unit in Canon's "smart" optical wireless system, the way your 430EXII can be used as a slave in that system. However, there is one model of Yongnuo flash that can act as an optical master (YN-568EXII), so if you used that on-camera, you ...

In your description you say you want a lens for family portraits, individual portraits and party pics. You already have your 18-55 zoom that would cover these ranges well, but you want a prime presumably for the extra speed, and maybe a bit more background blur am I right? Now, traditionally a portrait lens would be a 100/135mm equivalent, but for the ...

Unfortunately there is not much point to applying a fisheye effect digitally unless you happen to like the specific effect that a digital fisheye filter has. For example, it can sort of simulate the effect of looking through a glass ball. Actual fisheye lenses exist because they can get a very wide angle of view, and don't need to worry about keeping ...

The Canon Rebel T2i uses Canon lenses with an EF lens mount. You can mount these lenses to a variety of other cameras using an adapter. Here are some examples: Canon EF to Sony NEX Cannon EF to FujiFilm X-Mount Canon EF to Canon EOS M Typically you will only see adapters to mount a lens on an equal or lower end camera (not many people will mount a ...

We were able to get it working by dropping the shutter speed to 1/2 second for all the slave cameras and 1/4 for the master camera. The strobes are at 1/1000. This worked perfectly and it seemed like whatever the variability of the camera's shutter speed was too much for 1/60, 1/30 or 1/15.

Are you triggering via USB or just pulling the images via USB? From the BreezeSys website: How accurately can the cameras be synchronized? For best results the cameras should be set to manual focus and triggered via the remote release sockets. The figures below are for guidance purposes only. Please see this page for more information. ...

Given that the HS300 is an ELPH, I think it's unlikely that there's a separate clock battery. Quite a few cameras don't have one. But if it does, there will be a separate little compartment in the battery compartment itself. (See: ifixit guide for replacing a clock battery on the A590) What's more likely to be the issue is that the spring loading on the ...

As per camera (EOS REBEL T2i/EOS 550D/Kiss X4 Digital) manual the size of recorded video is 330 MB/min which mean 32GB card will be OK for you. But be aware videorecording will stop automatically after 29 minutes 59 seconds. Of course you can start it after this to shoot another ~30 minutes The mentioned speed of 30MB/s is read speed and write speed is ...

Your lens is damaged. One of your images (shown below) exhibits an abnormal amount of spherical aberration. It is not the kind of softness you would get when out of focus. Also, notice that the bricks on the left side are significantly softer than the right side, which indicates decentering. Both of these indicate that one or more lens elements have been ...
