The A3000 delivers excellent photo quality for the price.

I've been reviewing hardware and software, devising testing methodology and handed out buying advice for what seems like forever; I'm currently absorbed by computers and gaming hardware, but previously spent many years concentrating on cameras. I've also volunteered with a cat rescue for over 15 years doing adoptions, designing marketing materials, managing volunteers and, of course, photographing cats.
One of the cheapest cameras available with an APS-C-size sensor, the A3000 unsurprisingly delivers excellent low-ISO sensitivity photo quality for the price. You can start to see some initial detail degradation at ISO 800 in the shadow areas, but it's still pretty good.

Noise and JPEG processing, low ISO sensitivities
ISO 1600 is probably the highest I'd go with this camera, but for the money that's extremely good. Beyond that, you can see significant artifacts in all areas, and by ISO 6400 you lose quite a bit of detail.

ISO 100 JPEG
The A3000 with its kit lens does a fine job of rendering detail without looking oversharpened or processed.

ISO 200 JPEG
As you'd expect, ISO 200 looks excellent as well.

ISO 400 JPEG
The camera does a fine job of preserving texture and detail at ISO 400.
(1/40 sec, f4, pattern metering, AWB, ISO 400, 18-55mm lens at 18mm)

ISO 800 JPEG
This shot frequently displays some degraded edge detail and blown out highlights at ISO 800, but the A3000 handles it very well. You can see a bit of ringing on the text edges, but it's more than acceptable.

ISO 1600 JPEG
ISO 1600 shots look fine scaled down. See detail on next slide.

ISO 1600 raw vs. JPEG
There's a lot of detail degradation by ISO 1600, and you can reclaim a bit of it by shooting raw+JPEG, though the trade-off is grain.

ISO 3200 JPEG
By ISO 3200, most everything is soft and processed to extremes.

Color
The A3000 produces bright, saturated, if slightly punched-up colors.

Color and tonal range
While it tends to clip highlights like many consumer-targeted cameras, and the reds aren't always accurate, there's enough latitude to bring up shadow areas without introducing a lot of noise.
