Frequently Asked Questions

Cameras

SLR Booth has been designed to work with the most powerful and popular Canon and Nikon SLR cameras on the market today.  Our supported cameras list is where we add cameras that we have tested with the app here at SLR Booth HQ.  If your camera that you are interested in is not on the list, the best thing to do is download the app and try it out! If it does work, we’d love for you to let us know (info@slrbooth.com) so that we can add it to our test list and share it with the SLR Community.

I have all of the supported hardware, but my app can’t seem to control the camera. What’s up?

Make sure you grant permission for the app to use the camera when you plug it in, and don’t let the gallery or any other app have control of it.

Can I use the app without a camera?

SLR Booth was designed to control your powerful, high-end DSLR camera to vastly improve the quality of the photographs taken during an event. If you don’t have a stand-alone camera and want to use the camera in your device, there are many photobooth style apps that you can use, likely already installed on your device from the factory. These are lots of fun, but we love the control and photo quality we get from using our DSLR cameras.

Will this work with a camera using a Eyefi card?

You can certainly use an Eyefi card in the camera while shooting, but the communication between your tablet and the camera has to happen over USB, not wifi.

Special Considerations for Canon Owners

If your Canon is 40D or higher (ie, is not part of the Rebel series), the  LiveView silent shooting setting needs to be disabled in order for the flash to fire through the app. On the Rebel, the non e-TTL flash won’t fire in live view, so you may need to investigate using e-TTL compatible triggers, or using an onboard flash as a wink light to trigger an optical slave off camera.

You need to have a USB OTG adapter to plug your camera into your tablet. On some Canon Rebels you need to enable live view in the menu system on your camera.

Tablets

I am concerned about the battery life of an android tablet while using the app for a few hours. Any suggestions?

If your device only has a single USB port, you might not be able to charge at the same time. There are custom USB-OTG adapters for some Samsung devices that allow this, but if  you are looking for something that can run for hours on end, something with a USB port and separate power port will be your best bet.   AOC, Acer and HP all make 21-24″ all in ones with multiple USB ports and dedicated power.  An USB OTG Y cable would allow you to charge and connect to your camera at the same time. Support for simultaneous USB and charging is heavily dependent on the device, so be sure to research which cable/hub might work for your specific tablet.

Why can’t I use the app with my Samsung Galaxy Tab 4?

The Samsung Galaxy Tab 4 7″ tablet does not have USB-OTG support, so sadly it can’t control an SLR camera via USB. Most new tablets have USB-OTG support these days, but this particular one is quite popular, and doesn’t have that feature.

Do you have any recommendations on a low cost large screen tablet?

Acer, AOC and HP all made 21-24″ android all in ones, but they are becoming more and more rare. Here at SLR Booth HQ, we have an AOC A2272PW4T running Android 4.2.2 that we are really happy with.

What is the lowest version of Android that the app works with?

Version 4.1

Printing

Do you know if the [insert printer name here] is supported?

If a printer supports AirPrint, it should be supported. You can usually check this in the online printer documentation, such as this one for the HP6100: http://support.hp.com/us-en/product/HP-Officejet-6100-ePrinter-series—H6/4322969/model/4323174/document/c03116917/. 

We will be supporting Google Cloud print very soon (early 2016).

Can an earlier Canon Selphy printer (without WiFi) work, with a USB OTG -splitter (one USB to support the camera, one to support the Selphy 800 or 900?

The Selphys all require custom drivers to print via USB. If you want to print to an older Selphy that doesn’t have AirPrint support, you’ll have to plug it into a computer and share it over the network.

My venue does not have wifi … can I still print from the app?

If you are using a Canon Selphy, it has a built-in access point, so you can connect your tablet to it directly (of course you can’t email or share files through that connection, just print). You could also use your mobile phone as a wifi hotspot to connect your tablet and printer together.

I want to use a high-quality dye-sub printer for my events to support on-demand printing. Can I print over wifi from the app?

Most professional dye-sub printers don’t support wireless printing via AirPrint, so they need to be connected to a laptop or wireless print server to share them, so the SLR Booth app can find them. We use a Mac laptop to share a HiTi P510L printer at our larger events, and it works great. You could also use a Linux computer running CUPS to share the printer, or a wireless print server like the Lantronix ones (although device support on these is a bit spotty). The app has some very basic USB printing support built in (you can try it out – we have it working with the injket and laser printers in our office), but most high-end dye-sub photo printers need custom driver support. We are definitely looking at this for a future release.

My Bluetooth printer is not showing up … what’s wrong?

SLR Booth does not support Bluetooth.  We support AirPrint, and will support Google Cloud Print very soon (early 2016).

Backgrounds and Templates

Can I add a logo to any template?

You can add a logo to the built-in photo strip template. Otherwise, you can add a totally custom template with whatever logo you like.

I see that there is an option to add more templates, are there instructions on how I can make my own?

Yes! You can add custom templates – you just need a .png file with the photo placeholders as transparent areas. Take a look at our “Custom Templates” page – we are constantly updating that with new information and how-tos.

Troubleshooting

I’ve set everything up and I think that all of my devices are supported, but I’m getting an error message telling me that a compatible device is not connected. What’s up?

Often, this error is due to the camera not being started before the app.  Try these steps:

1.  Unplug

2. Exit SLR Booth app

3. Restart your camera

4. Plug back in and try again.

To find out for sure if your device supports USB host mode, download the app “USB Host Diagnostics” from https://play.google.com/store/apps/details?id=eu.chainfire.usbhostdiagnostics

When I took some test shots, I noticed that the files were saved on the Android, not the camera’s SD card. Am I doing something wrong? Is there a setting I missed?

You are using the free version of the app, which will only store downsized images with a watermark on your tablet. The full version will keep the full size originals on the camera.

I’m using a regular multi-photo template (not a filmstrip), but the photos are duplicated?

Check your camera settings – if you’re shooting RAW+JPEG, but don’t have the option to skip RAW file downloads, the app will get two photos downloaded for each photo you take.

I’m using a regular multi-photo template (not a filmstrip), but the photo placeholders are all white?

The graphics processors on some devices can’t handle large image sizes – try setting your camera to shoot a S or M sized jpeg file. Those are still large enough for populating templates, and as a bonus they transfer faster and take up less space on your device!

My photos aren’t showing up in the Gallery app

The default android gallery app periodically scans for new folders with images to display. So the first time you use SLR Booth (or switch to a new album), the gallery app may take time to notice it. You can force the gallery to update itself by doing the following:

Go to settings – apps – gallery
Clear cache, clear data, force close

Go to settings – apps – media storage
Clear cache, clear data, force close

Hard reset your device, and when you load the gallery app again, it will scan for new folders.

The app takes a few seconds to display photos after they’re taken

When a photo is taken, the camera first writes it to the local memory card and then SLR Booth downloads the photo from the camera over the USB cable and displays it. For large RAW images (which can be 10s of megabytes each), this can take a few seconds. To speed things up, consider shooting smaller sized images, or shooting JPEG images as these will transfer much quicker. You can also set your camera to shoot RAW+JPEG, but tell SLR Booth to only download JPEG images in the app settings.

The countdown doesn’t match up exactly with when the camera takes the picture

There is an option on the settings screen where you can configure the delay between when the shutter signal is sent, and when the camera takes the picture. This will be different for every combination of camera, focus mode (manual vs automatic), and ambient lighting. For example, a Canon 60D using “Quick” live view autofocus under indoor lighting takes about 1200ms (or 1.2 seconds).

The camera wasn’t able to take a picture, and now the screen is frozen

There are a variety of reasons the camera might fail to take a photo:

  • Unable to autofocus due to low light or subject being too close
  • Missing memory card
  • Low battery

When this happens, the app will wait for 30 seconds, and try again. If it was an autofocus issue, it may be successful. If it was a battery or memory card issue, it will stay in this loop until the issue is addressed.

The app won’t connect to the camera, I get a CP -1 12 error.

This generally means another app on your tablet is using the camera. Often this will happen when the gallery asks to use the camera when you first plug it in. Unplug the camera, turn it off and on again, and plug it back in. If the gallery asks to use the usb device, hit the cancel button. If the SLR Booth app asks for permission to use the usb device, grant it.

  1. Hi, i just bought the selphy cp1200, it appears on the slrbooth app but when i click print , it says sending to printer but nothing happens, can you help me please?

  2. Hi Greg,

    Is it possible to have a separate screen for Kiosk so that guests can look, upload their pictures after taking their photos?
    So basically one screen for taking the photos and another screen in Kiosk mode to view/upload pictures.

    Thanks,
    Dennis

  3. I’ve set this up with my canon for our wedding in 2 days… and have two URGENT issues.
    1) When we set the camera to manual mode, live view is very very dark (end photo is great)… but when in camera on auto mode, the live view is fine… any idea what is causing this?

    2) I have set the “start live view automatically” setting, but it still stays on the photo… I have tried both options on the other setting in which you choose whether to have the option to delete the photo or just tick it away…. makes no difference, does not go to live feed “automatically” on both options.

    • Hi Mike – the Canon rebels don’t have the ability to turn off the live view exposure preview. If you’re using a non-TTL flash, the camera doesn’t know about it, and assumes the final photo will be underexposed so it’s showing you a dark preview. Unfortunately, this is a limitation of the camera, so your options are to either upgrade your camera, use a TTL flash, or don’t shoot M (which will be tricky with the flash).

      For the restarting live view, make sure you enter a restart delay.

  4. Hy Greg,

    Can i use a DNP DS RX1 or HiTi P520L printer for 2×6″ (automatic cutting 4×6″) with slrbooth pro? I know on a pc with photobooth software it’s work great but it’s this option compatible with android sltbooth?

    Thank you in advance!

    • I’ve used the 2×6 cut feature of my HiTi P510 with SLR Booth – just select the appropriate paper size in the app. I don’t have a RX1 or 520 to test with however.

  5. So upset that this won’t work. I have a brand new Samsung TabE and an older Nikon D 200 and i cannot get the App to recognize the camera. grr…is there a setting I should have the camera in?? Thanks in advance.

  6. Hi Greg,
    When I enable “kiosk mode” I can only print or share the photo if I go to the gallery. Is there a way to show this options on the preview of the result?
    I have enabled all the options under the kiosk mode menu but still no button appears in the preview of the kios mode.
    Thank you for your support,
    Luca

  7. Hi Greg,
    Is there an option to take a 4 pictures frame without showing the preview of each one. I would like to show only the result of the 4 together. I think this would make the process quicker.
    Thanks,

    • Right now that isn’t an option. Setting the app to auto-approve each photo and lowering the countdown/delay times is the best way to speed it up currently.

  8. Hello,

    I’d like to setup simple photo-booth using slrbooth with Canon 1000D. As I have never done something like that, I need some info.

    I am not sure how the printing works – I am planning to buy epson l805 printer, that has wifi support. There is no information on the epson website if the printer supports google cloud print or airprint. (Airprint seem to be Apple system – is it working on Android?) Anyone tried this printer? If the printer doesn’t support cloud print / airprint – will be I still able to use the printer using my Windows 10 laptop connected to the wifi network?

    Also – what are the hardware requirements for the app (processor, memory) – I want to buy a cheap 10” tablet to use with slrbooth – will 1GB of RAM will be sufficient?

    Michael

    • A 1GB tablet should be OK hardware-wise. I don’t think the epson l805 supports AirPrint or GCP from what I can see, but you can generally share it using a PC or MAC and the app can find it.

  11. Hey Greg,

    I was trying to connect my android tablet to my laptop to print via FTP and I wasn’t getting anywhere with my lack of knowledge, but thankfully (somehow) I’ve managed to share my RX1HS printer through my MacBook and it’s showing up on the printer list in the settings as “DS-RX1 (AirPrint via MacBook-Air)”..but when I click the print button on a photo it says “Sent to Printer” yet nothing is coming out… do you know where the problem might be?
    P.S The network connection is strong.

  12. Hey,

    Just wondering if anyone reading this knows how to setup a print server connecting an android tablet to a DNP RX1HS Printer using Raspberry Pi? Can anyone break it down for me? I’m not really tech-savvy, but any general info on the steps would be much appreciated. (Looking into getting the DNP RX1HS WPS PRO, but as it’s not out yet I need to make due with something else in the meantime and shelling out to get the DNP WPS-1 would be a waste as a placeholder.)

    Really struggling trying to figure out how to connect my printer to my android…thanks in advance to anyone that can provide any information.

  13. Hi Greg,
    Used the app last night properly with all my kit and I just wanted to say a very well done! It’s great.
    However, between taking the photograph and showing the preview there is a large delay (to the point where I’m actually waiting so long I just press the cross to take another photo). I’m not shooting in RAW – just Large JPEG. Have you got any ideas of why this might be happening?
    Does my tablet need more RAM, or a bigger SD card?

      • On my Canon 40d (10Mp), SMALL JPG is still 1288 x 1936 pixels… more than enough for a full 4×6 at 300ppi (1200×1800)
        If the slrBooth app is set for 4×6 templates, you don’t need any more…in fact, a template with multiple openings should be fine with even less resolution. Smaller files to save, smaller to process,smaller to transfer from camera to your Android device.
        If I use my 18Mp Canon 7d, I still set for SMALLEST JPG.

        The only time you MIGHT want higher settiongs on your camera is if you intend to make large prints.

  14. Hey Greg,

    I don’t know if this is a silly question or not, but would using Google Cloud Print be a work around for printing on the DNP RX1HS without resorting to getting the DNP WPS? (Since the WPS is discontinued and I’m not sure when they’ll be releasing their newer model, I’m trying to figure out the best/quickest/cheapest way to print from my android device to the DNP… if the GCP won’t work, are there any reliable (and hopefully not too expensive) print servers that you know will work well with the DNP RX1HS?

    • Any Windows/Mac computer should be able to share the printer over the network for you using either GCP or AirPrint. Linux has some support for DNP printers, I know the DS40/DS80 are supported but not sure about the RX-1. If so, you could try using a Raspberry Pi as a print server – they’re $35, so you can’t get much cheaper than that.

  17. I’m having a hard time connecting the app to the printer. I’ve printed from the tablet to the selphy 910 via using the hotspot and it worked fine. But in the app it only shows: PRINT via FTP & Use Google Cloud Print. The paper size said: Use Google Cloud Print & searching for other printers. What do I do from here. Please help before Saturday that’s when my event is.

    • Hi Akeila. Make sure you are properly connected to the printer (either use the printer’s hotspot, or connect both to the same wireless network), and give the printer droplist a few seconds to search for printers and populate. If the droplist still says searching, it hasn’t finished yet.

  19. Can you help me with the setup using an Android tablet, HDTV, Android phone for wireless printing and a bluetooth button for trigger. Theoretically, I’d like to set the camera up with the TV in front for viewing since my tablet is only 7″. Then give them the bluetooth trigger linked to my Android phone running the app. How do I get the tablet to show up on the TV screen? Then I want to use my phone to send photos to printer. Please help. Thanks

    also, how much is the SLR Booth Pro app to download on the tablet? Thanks

    • Hi Clark – If your tablet doesn’t have an HDMI out that you can plug into your TV, I’d suggest looking at an Android TV box to run the main app on your TV. They can be found for under $50 usd, and then you don’t have to worry about batteries running out on your tablet.

      The app is free to to use with the single photo layout. To use the pro features including custom layouts, use of the remote and social sharing apps & hosted online galleries you can purchase either a single week pass for $9.99 usd, or a monthly subscription for $24.99

  20. Oh, alright…..maybe you guys could add color effects and photo effects to your next update? It would be much easier for the guests to choose which ever effect they’d like rather than switching the camera back and forth from bw to color and so on….

    Thanks!
