I want to do product photography. I want to capture some products high resolution image and want to edit images on photoshop. After editing i want to upload those on my website's service page. But the problem is, I do not have a DSLR camera. I have my mobile phone which has 13 px camera. Now my question, will this be enough to capture images for my work?

US$125 plus a cheap lens and some photo CFL lights, it will support tethering to a computer with the free Canon Utility and will be plenty for web product photos.

I found another image from the D70 that looks even better than the one I posted before. This was taken at 22 mm, which may be the sweet spot of the lens, at f/9.5.

What strikes me is that it's almost approaching medium format quality (I have a Fuji GFX 50S).

This is because the pixels are big compared to most current DSLRs – they are even bigger than the pixels on the GFX.

The D70's sensor is 23.7 mm wide, with 3008 pixels on the long side. 23.7:3008 = 0.078 mm pixel size.

The GFX's sensor is 43.8 mm wide, with 8256 pixels on the long side. 43.8:8256 = 0.053 mm pixel size.

So the D70 pixels are more than 40% larger than the GFX pixels. I'd say that the results are pretty good for a 14 year old sensor, but you can of course not print very big with only 6 megapixels. But for prints up to A4 (possibly a bit bigger), and for web images, this is actually a great camera, if you can live with the small screen and small viewfinder.

Lovely pic, and the really incredible thing is that a quick web search shows several D70 bodies on sale from photographic dealers at less than £60 each.

And for a little bit more, you can have it with the 18-70 lens.

When I got my current phone which has 12MP and will shoot RAW I compared it directly to a 12.7MP Canon 5D on the basis that they had roughly the same pixel count. I took the same photos with each. The result - no real contest. The DSLRs far superior lens and larger individual pixels resulted in images with far less noise and far more detail.

The phone camera is handy - in that it is always in my pocket, but out of choice use a camera.

As Dag points out - it is not that long since we were happily using 6MP SLRs (which will still outperform the phone) - those are now very cheap second hand. Would it be possible to get one that way - or even borrow one?

Yes, your suggestion was great. I will try to borrow a camera from someone for a day and do some photography. Thank you

You do not need a great expensive camera to capture very good images. You need a good eye, knowledge, good lighting, and good exposure setting and a steady cameras. My wife's iPhone 8+ 12MP cameras can capture very acceptable images. My old Cannon 1D Mark II 8MP with my cannon 300mm f2.8 L lens with good lighting will capture better quality image IMO. However her iPhone is handy fits in your pocket where my Canon 1D + 300mm camera is bulky at 10Lbs it is hard to hand hold. The iPhone 8+ was $800.00 the 1D+300mm was $8,000.00. Both cameras have their place and good images from either can be used on the Web. Our 1D Mark IV 16Mp

capture 16MP. So what its a bulky 3Lbs body for the web who need that? A 1K display image is 1920x1080 around 2MP where a 4k Display image is 3840x2160 images around 8MP. Image in web pages are not normally full display size. How many 33MP 8K Display 7680×4320 are out there?

If you have 4MP of high quality pixels your image will even print well.

My first DSLR was 6 megapixels. Those images can still be used for print, and if reduced to web-size it's not an issue at all.

Phone cameras have other problems. To get an idea, open in Photoshop and look at individual channels. Usually the blue channel is mush. There may be pixels, but both the lens and the sensor are of very inferior quality.

So was mine, a Nikon D70. It had a cheap 18-70 zoom which was very sharp, at least up to 50 mm.

Later I got a D300 with a 12 MP sensor, but the 18-70 couldn't cope with the increased resolution, and was useless with the new camera.

Below is a full size jpg (from an original raw) shot with the D70, 18 mm at f/11. The quality is quite impressive when viewed at 100%.

I went exactly the same route. D70 - D300, then D700 - D800 - D810. And then the Sony a7rII, although I still use the Nikons.

The D800 was the real paradigm shift, the one that turned the world upside down. But that was only possible because the optics had caught up. The real revolution is in lens optical resolution, forced by these new sensors. I still have some of the older lenses, both manual and early autofocus D-series lenses, and they are not in the same league.

With film I always used the single-digit models (F2-F3-F4) - but in the digital age these have taken on a different role, and they are now mainly press cameras optimized for high speed operation and low light conditions. Image quality is not the priority in these models.

Hi,

The answer is really - it depends. It depends on what level of quality is required, how the pictures will be used (website, print), what phone you have, lighting....

Here are a few considerations

The number of megapixels does not mean better quality. The sensor size is important. Here is a good article that discusses this point.

https://www.macworld.co.uk/how-to/iphone/best-camera-phone-megapixels-3502115/

I could go into other things like lighting but perhaps provide more information on what you actually are going to do and advice can be directed more to that.

I actually need for website. I am going to offer clipping path service which includes background removal, image masking, photo retouch, color correction, clipping path, shadow creation, etc. search with clipping path service, go any website and service pages. The images you are seeing, actually I need similar.

If you're doing serious photography work, a good camera would probably be the way to go. It would allow for much more control over focus. You could even pick the right lens for the specific photo required.

I looked at the following site:
https://clippingpathservice.com/our-services/

From what I can see in the above, I'm even more convinced that getting a good camera rather than just relying on your phone would be the best approach.
